# 1985 OLDSMOBILE MAINTENANCE SCHEDULES

#### MODELS/YEARS ALL 1985 MODELS

All 1985 Oldsmobile vehicles have a maintenance folder installed in the glove compartment at the time of production.

Two types of maintenance folders are used for 1985 Oldsmobiles; one for gasoline engines and one for diesel engines. Each folder has two schedules of service intervals (Figures 1 and 2). The schedule the owner should follow depends on how the car is driven.

Schedule I is to be followed if the car is driven under one or more of these conditions:

Operating in dusty areas;

Towing a trailer;

Idling for extended periods and/or low speed operation such as found in police, taxi or door-to-door delivery service; or

Operating when outside temperatures remain below freezing and when most trips are less than 4 miles (6 kilometers).

Schedule II is to be followed if none of the conditions in Schedule I apply and, as a general rule, the car is driven daily:

For a minimum of 15 miles (25 kilometers) or more; or Continuously for 30 minutes or more.

If a maintenance folder is lost, additional folders are available through your Zone Office.

Part numbers are as follows:

Early production Ninety-Eight models used a different maintenance folder from other cars. These folders should NOT be used in any other model, or in late production Ninety-Eights. However, the second type folder used in all other models MAY be used in early or late production Ninety-Eight models.

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.
