Rotella for GAS Engines

I use the diesel oil in Red, but it has a flat tappet cam and the new oils aren't designed for that while the diesel oils are.

I found it at AutoZone on clearance a few weeks ago, and bought 12 quarts for about $40, then sent in a rebate form, and got $24 back in about a week. Total price was less than $20 for 12 quarts.

This oil is designed specifically for gas engines with correct amount of Zinc/Phos that's specified by API SN+ requirements. It's not designed to be used in diesel engines.

Sounds like it is just another oil for gas engines trying to capitalize on a famous brand name.

Ok, so just another Synthetic option offered. Good to know.

Since when ??

Sorry for this post.
Turns out that diesels, newer ones anyway, DO have a kind of CAT but it is somewhat different than those used on cars.

^I dos not know that. Thanks!
