Re: which Rotella T
I did some work for a company that tested oils a few years ago, and after seeing the significant difference in synthetic over conventional oil, I've never chosen to use conventional again. I used the Shell Rotella 5W-40 Synthetic in three diesel trucks, a cadillac STS with a Northstar engine, two Saturn's, and two Ford Rangers. It's good stuff, now after reading the article somebody linked on the Forum, I plan to use it in my GZ 250. I've been paying about $9.50 a QT for Suzuki's Synthetic oil from the dealer, but I'd rather have the Rotella for less than half the cost!
