The other option is Chevrons Delo 400. I use RotellaT in my truck.....gas 302. RotellaT is a very good group I base. Delo is a group II base stock. As I learn more and more here.....I ask myself why I dont use the Delo 400 instead of the RotellaT.
I even asked Shell in an e-mail whyI should stick with them instead of switching to the Delo. Been over a month I think....no response yet.

Yep the other, other option is Mystik JT-8. That's what I run. Works great. $0.95 / quart on sale, with the diesel ratings, I cant complain!

I have heard that Mobil Delvac is very good too. Just saw that my local Meijers store carrys the Delvac 15w40 in 2.5 gallon jugs for $15.99.

When I do LOF's at work, some truckers specify Rotella T, others specify Delo 400. Others specify Shurcraft.
From what I understand, the difference between Rotella T and Delo 400 is the additive content. Delo 400 has more detergent in it, so you're getting "less" oil for lubrication. Rotella T, has less detergent than Delo 400, and stands to reason that there is more room for "more" oil to lubricate with. Either way you look at it, you could have "more" oil to keep yourself lubricated, or "less" oil that keeps the inside of your engine clean.
They are both excellent products. One thing I have noticed though, when it comes to changing the oil, the rig with Delo coming out has dirtier oil than Rotella coming out. That's a good thing. While Rotella still comes out black, I have to add this. If the oil coming out still looks clean, (ie: fresh out of the bottle) the oil isn't doing it's job, and it's time to start looking for a different oil.
