INFORMATION ON ENGINE OIL RECOMMENDATIONS REVISED SPECS.

SUBJECT: Information On Engine Oil Recommendations for 1994 Saturns

TO: Saturn Fixed Operation Managers

Information printed in the 1st edition of the 1994 Saturn Owner's Manuals indicates that only "SH" engine oils with a "Starburst" symbol (shown in illustration) on the oil container are to be used in 1994 Saturn vehicles. Due to the lack of wide spread availability of "SH" engine oil at this time, Saturn vehicles can continue to be serviced with "SG" oil without the Starburst symbol and with the doughnut shaped symbol.

NOTICE: If you use oils that do not have either the "Starburst" symbol or an API SH or SG designation, you can cause engine damage not covered by your warranty.

"SH" or "SG" must be on the oil container, either by itself or combined with other quality designations, such as "SH/CD," "SH, SG, CD," "SG/CD," etc. These letters show American Petroleum Institute (API) levels of quality. SAE 5W-30 as shown in the following illustration is still best for the vehicle. However, SAE 10W-30 can be used if the temperature is going to be - 18 degrees Celsius (0 degrees Fahrenheit) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 10W-40 or SAE 20W-50.

Oils labeled Energy Conserving II or identified with the Starburst symbol will save fuel when used in a Saturn vehicle.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
