What type of motor oil do you use for a 95 GMC jimmy?

The type of motor oil for a 1995 GMC Jimmy depends on the engine it has. You need to check your owner's manual for the specific recommendations. However, generally speaking, a 1995 GMC Jimmy likely uses a conventional or synthetic blend motor oil with a viscosity rating of either 10W-30 or 5W-30.

To be absolutely certain:

1. Consult your owner's manual: This is the most reliable source of information. It will specify the recommended oil type, viscosity, and API certification (like SL, SJ, etc.).

2. Check the oil fill cap: Sometimes the recommended oil type is printed on the oil fill cap.

3. Check the oil dipstick: Similar to the fill cap, the dipstick might have a recommendation.

Using the wrong type of oil can damage your engine. Always follow the manufacturer's recommendations.
