Perhaps you have never looked at your oil bill as a means of saving money. But it is. Oil is the one motoring supply you buy that has a direct effect on the entire operating cost of your car. Good tires wear longer-good gasoline gives greater mileage-but they are both straight expense. They have little direct effect on the other operating expenses of your car. Lubrication is conservation-the prevention of wear, the saving of undue expense, the lengthening of the life of your car.

Yet this small amount affects every other item of upkeep. There could be no more flagrant example of false economy than an attempt to save by buying a cheap oil. The old time saying of "it pays to buy the best"holds applies true ?f everything you put into your car-and espec1ally to the oil you use. How it Saves Incorrect oil adds to the operating expense; the correct oil saves operating expense .. Here are some of the ways in which it saves: · Reduces fuel consumption-because the correct oil seals the piston clearance and reduces waste of fuel into the crankcase. Reduces oil. consumption-because the correct oil does not "use up" as rapidly as incorrect or poor quality oil. Reducesfriction drag-because the correct oil enables every moving part of your engine to work smoothly and efficiently. Reduces repair bills-because the correct oil protects the moving parts from wear. Over fifty per cent of all engine • • troubles are due to faulty lubrication. Add to these typical savings the satisfaction of driving a car that is delivering full power and for which the yearly then you realize maintenance costs are only nominal-and that correct oil is not an expense, but a real saving. The Purpose of This Book Every year American motorists spend millions at least unnecessarily for engine repairs. This booklet, ''Correct Lubrication,'' given to you by the Mobil oil dealer, diagnoses the reason for much of this immense national waste. It deals simply and scientifically •with basic facts. It is a convenient and compact handbook of the lubrication of your car. 4 �... r. lV ' :t e '' ' How to CorrectlyLubricate Your Car T HE Vacuum Oil Company's Board of Automotive Engineers have made a close study of the lubricating problems of every car. They have not only determined the correct grade of Gargoyle Mobiloil as shown by the Charts of Recommendations for every make. and modet but they have also determined exactly how these oils should be used. Unless the correct oil is used in the right way you will not get the best results and so in the following paragraphs these engineers tell you exactly how to lubricate your car. By following these suggestions you will be assured of the very best possible operation with a min:imum of depreciation and costly repairs. Instructions for Correct Engine Lubrication Fill the crankcase regularly. Every time you start off for a trip of any length, or if you drive every day, raise the hood and see how much oil the indicator shows in the crankcase. ~r.;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 5 �CORRECT LUBRICATION If it is below the proper level, add a sufficient quantity of Gargoyle Mobiloil to make the level correct. If you make a habit of doing this regularly, you will not run out of oilyou will avoid a forced stop at some unknown garage which may not have the correct grade on hand. Do not overfill! An excess of oil does not assure better lubrication, but increases consumption, causes smoking, fouled plugs and carbon. If, however, after testing the level indicating device to make sure it is operating, you find no oil is being used or that the level is rising, it is certain that the oil is becoming d~luted .with unburned fuel which has worked past the piston rings. Why the Oil ''Thins Out'' Oil drained from an engine crank case after a period of use frequently seems to have become thinned out and to be lacking in lubricating value. This is particularly so in cold weather. The reason for this change in the oil is that liquid fuel has become mixed with it. Present day gasolines do not evaporate as readily as those sold a number of years ago. Only a portion of it vaporizes unless the engine is thoroughly heated. The remainder goes into the cylinders in liquid form and there it mixes with the oil film on the cylinder wall, thinning it out and destroying the piston seal. During the compression stroke some of the liquid fuel blows past the rings into the crankcase to mix with and thin out the oil there. The rest is only partially consumed and is therefore lost. As long as your engine is cold and you have to use the carburetor choke or change the carburetor adjustment to keep the engine running, this action is taking place and you are both wasting fuel and impairing the value of the lubricating oil. When gasoline is burned, one of the products of combustion is steam. If any blowby takes place, condensation of some of the steam in the burned gases blowing into the a ' V b d C f( tl M1.;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; �--.. ol lke I-en ter 1g, to or Jg ~e .t e e t CORRECT LUBRICATION crankcase is likely to occur if the engine is cold. As a result water accum·ulates in the crankcase and mixes with the oil. In cold weather the water-oil mixture may freeze into a pasty mass or ice may form on the oil screen, stopping the oil circulation. Sometimes the ice causes breakage of the pump. At times a thick black sludge or emulsion may form from churning the oil and water together with the sediment in the crankcase. This sludge also may clog the oil screen and the lubricating system, causing serious damage. Reducing Dilution As the engine heats up, more and more of the gasoline is vaporized; you do not have to use the carburetor choke to supply an excess of fuel and less is wasted. Blowby decreases and with this, dilution of the oil and water accumulations becomes less troublesome. / If you keep the radiator partially covered during cold weather, particularly if the car is frequently started and stopped, the engine will quickly warm up to its proper temperature, insuring thorough vaporization of the gasoline. Otherwise the increased radiation which is essential in hot weather, will overcool the engine and accelerate dilution and emulsion trouble. By having the mixture adjusted correctly, the valves and ignition system in good condition, and by using the carburetor choke as little as possible, good combustion will be assured with a resultant decrease in dilution and fuel waste~ Why Crankcase Draining is Important • The dilution which takes place while the engine is warming up and while the carburetor choke is in use cannot be prevented. As a result, the oil becomes more and more diluted as the engine is used. In addition, the oil becomes contaminated with /articles of worn metal, carbon and road dust which ten to cut the working surfaces as the oil thins out. To /revent the friction and wear which occur with dilute oil, this should be drained from the crankcase and • ~;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 7 �CORRECT LUBRICATION replaced with fresh oil of the proper grade at regular intervals. If your car is new, drain it after the first 500 miles of service. Thereafter, drain every miles in the summer and 1000 every 500 miles in winter. Commercial vehicles should be drained every 750 miles in summer and every 500 miles in winter. Cars or other uni ts which are operated in cold weather without radiator covers will require much more frequent draining if trouble is to be avoided. A Few Suggestions on Draining The old oil should be drained off when the engine is hot and the oil is most fluid and thoroughly agitated. This will carry off all the sediment that is circulating with the oilthe rest cannot be gotten rid of without dropping the oil pan. If the engine design permits, the oil screen should be taken out and cleaned after the first 500 miles. Thereafter it should be cleaned at least every 5,ooo miles. . Do not Flush with Kerosene! One of the principal reasons for draining is to get rid of badly diluted oil. With certain lubricating systems, the kerosene cannot be completely drained from the crankcase. In such instances it remains to dilute the fresh oil added. In some engines the use of kerosene. may break the pump prime and unless you know how to reprime the pump before starting the engine, there is a likelihood of the bearings ' being ruined before oil circulation starts. Do not flush with kerosene.'The risk is too great. If flushing is deemed necessary, use one or two quarts of fresh oil. ,..a;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 8 �- ] lt m- ery rnJ :er. ~ .m• 10 en 1er ·nt :it .ll il ,e :r CORRECT LUBRICATION Oil Pressure Most cars are equipped with a pressure gauge to inaicate oil circulation. As long as the gauge indicates any pressure when your engine is in operation, it is beThe ing properly lubricated. amount of pressure means nothing, just as long as some pressure is shown. The pressure will be high when the oil is cold, or when the engine speeds up. It will be low when the oil is heated, when the engine slows down or when the oil becomes diluted. Bearing wear will also decrease the oil pressure where force or full force feed systems are employed. If no pressure is indicated, stop and find out why. See lubrication troubles and remedies, page 2.8. Where excessive oil consumption, spark plug fouling, smoking, and car'bon formation exists, and the engine is known to be in good mechanical condition, a correction can generally be .effected by reducing the oil pressure. Better have this done by your service station. With force feed systems, worn bearings also frequently cause oil pumping and correction is only possible by properly refitting the bearings. Avoid Heavier Oils in Worn Engines No oil can take the place of metal that has been worn away. No oil can seal piston rings that have become misfits in their· grooves. Blowby will take place with any oileven the heaviest-bodied oil-under these conditions. Using an oil heavier than recommended for your engine is certain to cause an excessive fluid friction loss and induce detrimental carbon formations. In some cases it may cause ser~ous damage from its not being circulated by the lubricating system.

Then use the correct grade of Gargoyle Mobiloil in the correct way. Fan Bearing Fan bearings are frequently neglected. These bearings are all isolated from the lubricating system of the engine and so need separate and periodic attention. On practically all motors the fan hub is hollow and serves as a reservoir for the lubricant. Every 300 miles lubricate these bearings using either a grease such as Mobilubricantora heavy engine oil according to the design of the bearing and the lubricating fitting provided. Water Pump Water pump shaft bearings are usually provided with grease cups. It is very i1nportant that these bearings are periodically lubricated. Every 300 miles screw down the grease cups one or two turns and when empty refill with a high quality grease such as Mobil ubrican t. Generator As a general rule, the generator requires little attention .. However, unless the bearings are periodically lubricated excessive wear and costly bearing replacement will result. 10 �CORRECT --------- n rot 1m ucn ·rne rne LUBRICATION Generators in all instances are provided with small oil cups for the armature bea~ings.

Every 1000 miles fill these oilers with four or five drops of light engine oil. Distributor The distributor shaft bearings are designed either for oil or grease lubrication. In either instance, however, periodic attention is very necessary. Lubricate the distributor shaft bearing every 300 miles with either engine oil or grease according to the construction used. Rocker Arms and Parts In engines of the valve-in-head type these parts are usually automatically lubricated by engine oil. Where these rocker arms, however, do not receive lubrication from the 11 �CORRECT LUBRICATION engine it is very essential that they should be periodically lubricated with engine oil. Either oil cups or wick filled oil wells are employed. Every 300 miles fill or soak these oilers with engine oil. Engine Support Arm Many engines are of the three point suspension type. In such designs the manufacturer provides for the lubrication of the center engine support arm bearing. Every 1000 miles lubricate this bearing with either oil or grease according to the design. How to Correctly Lubricate the Chassis Steering Gear C\INCE the operating mechanism of all types of steering 0 gears are such ·that they work under heavy pressure, correct lubrication is very essential to prevent premature wear and to proviqe easy steering. ~_3:.~---, Steering gears are of the worm and worm wheel; worm and split nut; or the worm and nut type. The housing at the bottom of the steering gear column should be kept filled with either a high quality grease or a heavy gear oil such as Gargoyle Mobiloil ''C,'' depending upon the construction used. 12 �............

In the wet plate type of clutch, slippage or grabbing usually results unless the proper lubricant is used. arm ? I In the wet plate type the clutch housing should be kept filled with the proper amount of a mixture of 50% kerosene and 50% light engine oil. In the dry plate type, no lubrication is necessary. In the cone type of clutch it is only necessary to periodically apply a small amount of neatsfoot oil or leather oil dressing to the clutch facing. For best operation this should be done every 2.000 miles, after the facing has been cleaned with gasoline. Clutch Release Bearing The clutch release bearing is subject to hard usage and because it is out of sight is quite frequently neglected. Unless this bearing is periodically lubricated it is almost certain that M1;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 13 �CORRECT LUBRICATION premature wear will take place with resultant costly bearing replacement. In instances where this bearing is not lubricated from the transmission, the manufacturer provides for either oil or grease lubrication. Every 600 miles lubricate these bearings with either a heavy gear oil or grease as the construction permits. Transmission One of the most important units requiring lubrication is the transmission. Hidden under the body of the car, this is of ten neglected and usually incorrect lubricants are used. Practically all transmissions are designed to be lubricated by a fluid gear oil. The oil used, however, must be of a special character and of a very heavy body to supply the necessary degree of lubrication under the high bearing pressures encountered. In addition, the oil used must be of such a character as to circulate· thoroughly and readily under all temperature conditions and also must not channel. For the correct lubrication of the transmission Gargoyle Mobiloil ''C,'' a heavy bodied fluid gear oil, should be used. In some cases where a fluid oil can not be employed, a semifluid oil, Gargoyle Mobiloil ''CC,'' is recommend~d. Follow the recommendation shown on the Charts on pages 38 to 59· In most cars the transmission is built with a combined filling and level testing plug. Fill casing until the lubricant is level with this filling hole. Do not fill above this level and if necessary let it drain off to the level of this opening. If a level testing plug is not a part of the transmission case, it should be filled until the oil just covers the countershaft, where this shaft is below the main or spline shaft. ~·;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 14 �CORRECT LUBRICATION ............._ 1,. •.

Every 1000 miles inspect the transmission and replenish the supply of oil if necessary. Every 5000 miles drain out the old oil and replace with a fresh supply. The oil should be drained immediately after the car has been in operation, for the oil will be warm and will flow out more readily. Universal Joints From a lubrication standpoint, there are two types of universal join ts used; those which do not require lubrication ( the fa bric type) and those which require lubrication (the metal enclosed type). The metal enclosed type is designed for either oil or grease lubrication, depending upon the construction. Unless these joints are periodically lubricated excessive wear is certain to occur, resulting in frequent and costly replacement. For universals which require oil lubrication the joints should be filled with a heavy gear oil such as Gargoyle Mobiloil "C" every 1000 miles. In the joints which require grease lubrication the casings should be kept filled with a high quality grease such as Mobilubricant. Inspect every miles and replenish lubricant if necessary. 1000 Differential and Final Drive The rear axle differential and final drive gears are encased in an oil tight housing permitting the use of a heavy bodied fluid gear oil. In many differentials an oil must be used which will provide proper distribution to the isolated pinion drive shaft bearings. M9;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 15 �CORRECT LUBRICATION In most cars a combined level testing and filling plug is provided and the housing should be filled with a heavy gear oil such as Gargoyle Mobiloil "C" until the level of the lubricant is even with the filling hole. Some differentials have a separate level testing plug and a filling plug located on the top of the housing. In this type fill with oil until it runs out of the level testing plug. Where no level testing plug is provided the oil should be at such a level as to just cover the top of· the lowermost· teeth on the bevel ring gear. In most designs if the lubricant is approximately a half-inch below the bottom of the differential cage the teeth on the bevel ring gear will be properly covered. Do .not over-fill the housing. Over-filling usually causes objectionable leakage and brake slippage. Always allow the lubricant to drain off to the proper level. Inspect every 1000 miles and replenish the oil if neces-. sary. Every 5000 miles drain the old oil and replace with a fresh supply. Drain differential immediately after car has heen run. Under this condition the oil is more fluid and will flow out faster. Drive Pinion Bearings These bearings are located in unit construction with the rear axle and are encased in the housing immediately where the propeller shaft enters. These bearings operate under heavy loads and stresses. 16 �~ ........... ~ CORRECT LUBRICATION In some cars these bearings are automadcally lubricated from the oil in the rear axle. In other cars, however, these bearings require a separate supply of lubricant and the manufacturer makes provision for either oil or grease lubrication. Under these conditions these bearings should be lubricated every 1000 miles with either a heavy gear oil or grease, depending upon the construction used. noi) I tnt m )IV Wheel Bearings Most front and rear wheel bearings are lubricat~d by greasewhich is applied by removing the hub caps. In a few designs of rear wlieel bearings they receive a supply of lubricant frnm the differential housing. In all instances, however, periodic lubrication and attention is necessary. Every 2.000 miles remove the hub caps and repack wheel bearings with a high quality grease such as Mobilubricant. Every 5000 miles the wheels should be removed, the bearings should be cleaned in gasoline and then repacked with a fresh supply of lubricant. Spring Shackle Bolts Correct lubrication of the spring shackle bolts will do much to prevent unnecessary squeaks and rattles and premature bolt or bushing wear. Spring shackle bolts are either designed to use a fluid oil or a semifluid lubricant and usually a pressure lubricating system is employed. Where pressure lubricating systems are employed Mt;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; eh 17 �CORRECT LUBRICATION which require the use of a heavy fluid oil, Gargoyle Mobiloil •·c'' should be used. Where the pressure lubricating system necessitates the use of a semi-fluid lubricant Gargoyle Mobiloil "Cc•· should be used. Greases are not recommended for these bearings and if used will tend to cake up the oil leads and oil holes. On some cars engine oil cups are /rovided. With such installations engine oil should be use . For best results all spring shackle bolts should be lubricated every 300 miles regardless of the type of lubricating system used. Steering Knuckles and Steering Connections Most complaints of hard steering are due to lack of lubrication of the steering knuckles and connections. } f f Lubricate these parts regularly every 300 miles. Do not use grease. Follow instructions for spring shackles. Jacking up the axle when supplying the lubricant relieves the pressure on the steering knuckles and facilitates their lubrication. Springs It is important that spring leaves should not rust and satisfactory lubrication will be obtained by painting the sides of the spring leaves every rooo miles with engine oil. 18 H f( 1[ e 1~ fi d{ cy sp p �' t IJt~ ~1 0~"Q 1\~ or lbJ1r: ~ni litti'. om, EngineTroublesand Remedies HE suggestions on the following pages are made to assist operators in effecting emergency repairs. Where serious trouble is discovered, we recommend that you call in a com pet en t service man for its correction. Proper engine operation depends primarily upon three 1. U nin terru pted ignition. factors: 2.. Unfailing fuel supply. 3 . Good com press ion. When an engine refuses to start or stops suddenly, first find out which is at fault, ignition or fuel supply, by applying the tests given under Ignition and Fuel Systems on the following pages. The trouble can then be located by following the additional suggestions under those headings. Irregular running or misfiring, easily recognized by an uneven exhaust, are due to incorrect mixture or to defective ignition or poor compression, the latter usually being confined to one or two cylinders. To locate the defective cylinders short circuit each spark plug in turn. When defective cylinders are reached no change in exhaust noise or engine speed will be apparent. Examine spark plugs and test compression of those cylinders.

Therefore, if the oil gauge. shows no pressure, or if the sight feed indicates no flow~ stop at once and investigate. Possible sources of trouble are indicated here. 1. Lack of oil.-Refill crank case reservoir daily to proper level with correct grade of Gargoyle Mobiloil. See that indicator operates freely. Test operation of indicator frequently. Always start with full oil reservoir. PRIME Hl:J?E. ef' 2. Pump not primed.-Fill through priming plug in pump body or through disconnected oil pipe. This trouble usually results from running without oil in the system or washing crankcase with kerosene. 3. Pump Connections loose. -Results in failure of pump to prime.

If the motor cranks the engine very slowly and then stops, or if the starting mechanism is heard to engage but the engine does not turn, the trouble is almost invariably electrical. The possible sources of trouble are indicated below. Always make sure that the gear shift lever is in neutral before hunting trouble. ~ ► Hold clutch QUtwhen operating starter. ◄ ~ 1. Battery run down.-Lights dim or go out when starter button or pedal is pushed. Have battery recharged and tested for dead c-ells. 2.

Have replaced. 31 , �CORRECT LUBRICATION Chassis Troubles OIL 1. Squeaks.-Cause is lack of lubrication of moving parts or loosened parts. Apply light engine oil to any joints showing traces of rust, particularly spring shackles, spring leaves, steering and speedometer connections, body joints, hood hinges and fastenings. HERE 2. Rattles.-Caused by looseness of parts, particularly spring shackles, steering connections, hoods, fenders, tire supports, doors, top joints, clutch and brake connections, universal joints. Lubricate and tighten fastenings, using lockwashers wherever possible. Take up lost motion in working parts. Provide rubber or felt bumpers where possible. . 3. Hard steering.-Results from lack of lubrication of steering gear connections, particularly steering knuckles. Also too close adjustment of steering gear. Lubricate all parts freely and have gear properly adjusted. 4. Broken tight. springs.-Keep spring clips 1,I er W ba ca M1c;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 32 �CORRECT LUBRICATION Chassis Troubles 5. Rapid tire wear .-Due to front wheels not in alignment. Tire quickly wears flat on tread. Jack up front axle, spin wheels, making chalk or pencil line on center of tire treads. Measure distance between lines on tires at front and rear of wheels. Wheels should "toe in" about one-eighth of an inch, with no play in steering knuckle tie rod pins. NEATSfOOi OIi. 6. Clutch engages abruptly .-Cone clutch-soak leather with neatsfoot oil and adjust facing springs. Disc clutch-have adjusted. Spider may be worn. k 0 7. Dragging brakes.-Car lacks pow er. Test by jacking up axle and turning wheels. Adjust both top and bottom halves of brakes.

To insure this, the best way is to keep a supply in the Home Garage. With this, fresh, clean oil can be added as needed-at a saving of time and money. A 5-gallon can of Gargoyle Mobiloil or a 15-gallon steel drum with faucet attached will answer this need. Here are three reasons why a home supply of Gargoyle Mobiloil is becoming so popular: r. Five gallons of oil bought in single quarts means twenty trips for oil! You make only one trip when you buy in 5-gallon cans. 2. With a home supply of Mobil oil you can always have the proper amount of oil in your engine before driving away. This means much better operation. you are using genuine 3. You are sure-always-that Gargoyle Mobiloil. You eliminate the necessity of accepting some other oil from a dealer who may not have Mobiloil.
