I wouldn't doubt that. I just went and picked up 3 gallon jugs of NAPA 15w-40. Currently on sale for $9.99 EA. That's a real good price! Normally $13-14 a gallon.
My 6.5 Diesel runs 21.5:1 compression, so it makes the oil real dirty. Wonder if they have any recommended interval for it?
Thats a good great price sure,the 6.5 guys usually change them more often i had a '99 before this truck and did 5k with that.

Ha Ha I caught that too Math and grammar just aren't taught anymore. You'd think the schools would have more time to teach....they don't say the pledge of allegiance anymore
edit Better contribute to the OP Amsoil in everything except the hydros of the Cats. Cat spec is an emulsifier, Amsoil hydro oils are only a demulsifier

Pennzoil in gas engines, DA Lubricants Reliant 15w-40 in all the diesels. Used to run Rotela but have changed since DA is cleaner and more efficient oil. Not knocking Rotela 1 bit!

Mobil 1 for me. I ran synthetic penzoil once. At around 4000 miles both vehicles were 2 quarts low. Never had that happen before or after with Mobil 1.
