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?

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.
