What kind of oil does a 1989 Chevy c1500 take?

The type of oil a 1989 Chevy C1500 takes depends on the engine it has. There were several engine options available that year. To know for sure, you need to check your owner's manual or the sticker under the hood.

However, generally speaking, for that era, conventional 10W-30 or 10W-40 would have been common recommendations. But again, consult your owner's manual for the *specific* recommendation for your truck's engine. The manual will also specify the oil capacity.

Using the wrong oil viscosity can damage your engine. Don't rely solely on online information; always check your vehicle's documentation.
