Why? Cat has their own oil, and I have heard from tons of Cat people that it comes in the same shipment as thier Mobil oil.

Is that a Peterbilt "factory fill?"

BTW, I personally use Castrol's Tection oil, but thats my own truck, My dad treats the others to Delvac.

Cat and Mobil oil are the same.

My KW with a Cummins came factory filled with Delo as well, yet the only engine oil that Cummins specifically recommends is Valvoline Premium Blue...and that's for extended drain intervals even.
