OIL AND FILTER CHARTS REVISED SPECS

VEHICLES AFFECTED: 1985 Chevrolet Owner's Manual.

The engine oil and filter change interval charts shown on Pages 5-6 and 5-9 of the subject Owner's Manual, Part No. 14085215-A, are incorrectly located and are reversed as to engine application. The chart shown on Page 5-6 applies to Diesel Engines and the chart on Page 5-9 pertains to gasoline engines. The 'B' edition of the Owner's Manual will show the charts in their proper application.

The charts are reproduced below with the proper identification and should be used when determining the correct oil and filter interval change for your 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.
