1952 Buick Lubricare Instructions

Wipe off any excess Silicone Compound with a cloth to reduce accumulation of dust on the awning gasket.

Open the door and operate the flipper by hand 10 or 15 times to work the lubricant into the hinge.

 

BUICK HD CONCENTRATE

In accordance with dealer requests for a detergency concentrate suitable for use in Buick crankcases, Buick HD Concentrate has been added to the line of factory engineered parts.

This concentrate (Group 1.850, Part No. 1161919) is a compound of the materials used by oil refiners to manufacture high detergency motor oils. It is intended for use in engines operating under aggravated conditions where engine deposits, rust and corrosion cannot be adequately retarded by motor oils readily available to the average motorist. One can of HD Concentrate, when used with a good Heavy Duty Type motor oil, will raise the detergency level of the crankcase mixture to equal that of a Series 2 Heavy Duty oil.

Buick HD Concentrate is especially recommended for engines operated under restricted conditions such as frequent stops, short trips and slow speeds where such symptoms as sticking valves, valve lifters and rings are noticed.

As in the case of any approved materials, Buick HD Concentrate has been thoroughly tested at the factory under all conditions and may be safely used with any reputable Heavy Duty Oil. It does not contain any agent which is harmful to engine components and it may be used continually, although it is normally unnecessary to use it with every crankcase refill.

NOTE: This material is not to be confused with so called friction reducing, gum removing, mileage improving, etc. oil additives and engine flushing compounds currently available under numerous trade names.

The recommended procedure for use of Buick HD Concentrate is as follows:

1. Idle engine until thoroughly warm (approximately 20 minutes) using the existing oil.
2. Drain hot oil and oil filter can. Change filter element.
3. Refill crankcase to correct level with Heavy Duty Type motor oil and one can of Buick HD Concentrate. (In very unusual cases it may be necessary to use two cans of concentrate.)
4. Run engine for 30 minutes or drive car at fairly high speed for 30 miles to assure that new oil and concentrate have thoroughly mixed and circulated throughout the engine and engine parts.

 

ADDITIVES IN LUBRICANTS

ALL MODELS

Service Men are urged to avoid any field attempt to improve lubricants by adding so-called “dopes, solvents, friction reducing compounds, and other trick materials” to the products supplied by reputable marketers.

The use of these materials in engine oils, Dynaflow transmission fluids and differential lubricants is entirely unnecessary to the proper operation of a Buick automobile.

Certain of these additives have reportedly caused damage due to the formation of oxidation products, varnish and sludge in Dynaflow transmissions.

AUTOMATIC TRANSMISSION FLUID, TYPE A has been designed to have the required properties for satisfactory operation in the Dynaflow. The use of supplementary compounds in Dynaflow oil may cause malfunctioning of the unit and necessitate extensive repairs. Only “Special Buick Oil For Dynaflow Drive” or” Automatic Transmission Fluid, Type A”, identified by an Armour Research Foundation Qualification Number (AQ-ATF—), are recommended for use in the Buick Dynaflow Drive.

 

REAR AXLE LUBRICANT

ALL MODELS

Several cases of sudden ring and pinion gear failure after many thousands of satisfactory miles have been traced to use of inadequate lubricants in the axle. It is felt desirable at this time to emphasize care in following existing recommendations regarding rear axle lubricant. These recommendations are summarized below:

1. The Buick axle is factory filled with a special Hypoid Lubricant (90). This oil is specially blended with additives which give maximum protection against scoring of axle gears.
2. No periodic or seasonal change of axle oil is required, nor is draining and flushing recommended except with part of repair procedures.
3. Multi-Purpose SAE 90 (often called “EP” or “Hypoid “) oil made by a reputable manufacturer may be used for make -up additions to bring .the axle oil to proper level, but must not be used to complete fill because it will not assure proper protection of the gears under all conditions.
4. If the axle is drained for any reason, it must be filled using only factory Hypoid Lubricant (90), which may be obtained from any Buick Parts Warehouse under Group 5.535 No. 1393524. This is the 2 qt. container.

 

5-W MOTOR OIL

Servicemen, particularly in the Northern sections of the country, will be interested in learning of the availability of new, improved SAE 5-W motor oils. The improved 5-W oils combine easier starting at low temperatures with the equivalent lubrication protection and oil economy of high quality SAE 10-W oils at operating temperatures. They represent a completely new development and they should not be confused with 5-W oils previously available on the market. The new 5-W oils will be generally identified with the new American Petroleum Institute classification “For Service MS”. Look for this designation on the container. They will all be Heavy Duty Type oils.

The improved 5-W oils have been thoroughly tested and are recommended for use in Buick engines whenever the anticipated temperatures will be 10degrees Fahrenheit below Zero or lower. They should be used not only at the lower temperatures, but may be retained in the crankcase for use during the warmer days that occur during the winter season. The practice of using kerosene with engine oil in an emergency should be discouraged because it is of temporary value only.

It is suggested that Buick organizations in the colder areas arrange to have this oil on hand for the coming season. The improvement in low temperature engine lubrication and the greatly reduced starting loads will assist Buick owners to enjoy trouble-free motoring during the winter season.
