How much oil in chev 3100 engine?

The oil capacity for a Chevrolet 3100 engine depends on the year and specific engine configuration (e.g., the exact displacement, whether it's a straight-6 or V8). There's no single answer.

To find the correct oil capacity, you must consult your owner's manual. The manual will specify the amount of oil needed with and without a filter change.

Alternatively, you can:

* Look up your engine code: The engine code (often found on a plate on the engine itself or in your owner's manual) can help you find precise specifications online through Chevrolet resources or reliable automotive websites.

* Check online resources: Websites like the Haynes or Chilton repair manuals often have this information, but you'll still need your engine's details.

Do not attempt to guess the oil capacity. Using too little or too much oil can severely damage your engine.
