What can low oil do to my GMC C1500 engine?

Motor oil lubricates important engine parts. If you're low or out of oil, engine parts can grind together, generate too much heat, and cause your C1500’s engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.

Can I change my GMC C1500 oil at home?

Changing engine oil at home isn’t as simple as it’s made out to be. It requires special tools and old oil must be disposed of properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also with your vehicle down the road.

Why is my GMC exhaust smoke gray or blue?

You could have an oil leak and have a case of burning oil. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, fried piston rings, or damaged cylinder walls.

What does it mean if my GMC C1500 oil light comes on?

If you’re overdue for an oil change, it might trigger your GMC C1500 oil change reminder light. If the oil pressure light is illuminated, it could be due to low engine oil, a failing oil pump, a malfunctioning oil pressure sensor, or a clogged oil filter.

Does my C1500's oil filter need to be changed during my oil change?

You should replace your GMC C1500 during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.

Your 1991 C1500’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. No matter the mileage, your C1500 may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice excess vehicle exhaust.

More frequent oil changes generally won't harm your GMC C1500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
