Just curious what you folks run in your Dmaxs. I've been using Redline 15W40 synthetic. I've got redline synthetic in my differentials, too.

Delvac 1! I voted under Mobil 1

Amsoil

Same comment as blnagel, I assume Mobil 1 means Mobil Delvac 1 (or Mobil Truck and SUV).

Other- Shell Rotella 15w40

I use Valvoline Premium Blue 15W-40. It has a great additive package.

Shell Rotella.

Shell Rotella 15W-40.

Shell Rotella 15W-40 here too.

Plus 50 John Deere oil. Lasts twice as long. Run it in everything...

Far more important than the oil type is the regular changing of it!

Schaeffers supreme

Schaeffers also every 5000 miles

SCHAEFFER'S SUPREME 7000

Other = Shell Rotella T 15w-40

Rotella T syn. 5w 40w . Did any of you notice a 5-6 degree temp drop when you switched to syn. oil? I did and can not believe it yet.

The "Other" shows 37 users while the total of all the listed oil users is 36 . Just what oil do the "Others" use? I haven't seen any Mobil One rated for diesel, is there a secret place to get it?Edited by: Bill Gisse

Shell Rotella T 15w40. Change every 3K and had an O.A done at 37K with excellent results. Well below normal wear limits.http://www.dieselplace.com/forum/smileys/Big Smile.gif

Chevron Delo 400. Considering change to Mobil Delvac.

The Mobil 1 for Diesels is Delvac 1 5w40. Around here I see it at Napa, Advance Auto, WalMart, and truck stops.

Break in on Northland, now Delvac.

Delvac 1

I use Petro-Canada's 5w-40 Duron sythetic in my truck. Very high quality oil. It gets very cold up here sometimes as low as -40 degrees ( fareinheit or celcius are the same at this point ) plus I change it every 3000 miles and ignore that oil life monitor. If it is as good as their milage calculations in the truck then engines would be droping out. Edited by: AbsoluteGMC
