Can I prevent engine sludge in my GMC?

Yes, regular oil changes really ARE important! If you’re driving around with old motor oil, the broken-down fluid (and resulting debris) isn’t protecting your engine parts. In fact, it may even be causing slow damage to your GMC Sierra 2500 HD’s engine! Routine oil changes may seem like an insignificant maintenance task, but trust us – your future self will thank you.

Is GMC's recommended maintenance really that important?

One of your best defenses against paying for repair services is following GMC's recommended maintenance schedule for 2003 Sierra 2500 HDs. GMC built your vehicle and can best anticipate when something will need to be serviced or replaced.

How much information should I provide the technician about my GMC?

No one likes having to get repair service on their trusty GMC Sierra 2500 HD, but you can help minimize the hassle. As soon as you notice something that doesn’t seem right in your vehicle, make a note of the date and what happens (and write it down so you don’t forget!). Are there new noises coming from the engine? Does something smell funny in your A/C vents? The more information you can give to your technician, the better! We’ll be able to find the root of the problem quickly and address it before it gets any worse.
