How do you change the oil on a diesel truck?
I need to change out my GMC Canyon’s fuel, but I have the Duramax model and I’ve never done an oil change on a diesel engine before. What should I do?

It’s always a good idea to be proactive about your truck’s engine maintenance—your
GMC Canyon
would certainly thank you if it could. Here’s how to change the oil on a diesel truck: - Warm up your engine to its operating temperature, then turn it off
- Place an oil pan under the drain plug and remove the plug using a 15mm socket and ratchet
- Remove the oil filter canister using a 27mm socket and ratchet
- Dispose of the old oil filter and O ring
- Install a new filter and O ring into the canister—lubricate the O ring with fresh oil
- Replace the canister
- Replace the drain plug—and ensure that it is tightened properly
- Using a funnel, pour 5.5 quarts of 5W30 Dexos 2™ approved oil into the engine
- Replace the oil fill cap
- Turn on your engine and check for leaks while it circulates, then turn it off
- Using the dipstick, check your engine oil level and top off as needed
Be sure to check your owner’s manual to see if there are any specifications on the oil or oil filter that you will need to adhere to. You’ll want to make sure to use the approved materials to avoid voiding your warranty and damaging your truck.
Changing your oil regularly keeps your truck’s engine well-protected—as does purchasing quality car insurance.
