But regardless of what you use I wouild start with a quart of the GM EOS (engine oil supplement) Can't go wrong there. A lot of folks are going to the Rotella as is mentioned in several posts a while back. I can confirm this as I delivered parts for a company for quite some time and you would be surprised how many shops are useing the Rotella. Most of them are using the 15-40wt. Just more info for you to decipher!! | | |
