Synthetic or Full Synthetic


Asked by Dec 31, 2015 at 07:41 AM about the 2004 Pontiac Grand Prix GT2

Question type: Maintenance & Repair

Ive heard different things about oil but I have
189xxx miles on my 2004 Grand Prix GT2. Would it
be better to run full synthetic or just regular high
mileage synthetic?

What oil are you running now?

1 out of 1 people think this is helpful.

Conventional 5w-30


Then with this many miles on it I would NOT switch to a synthetic oil. I did this on one of my vehicles and it messed the motor right up. My opinion with that many miles on the car I recommend not switching to a synthetic oil. Stick with a good conventional oil, high mileage maybe, Just do your regular oil changes.
