Hi all,

I just bought my first 2000 Pontiac Grand Prix GTP and not wanting to make any mistakes with this car, I have read some of the threads that have been posted and found out some helpful insight. My question that I have is, can I put the mid grade premium gas or do I need to use the high grade premium and do I need to use Coolant with Dex-cool in it or does it really matter which coolant I use?
