What are the differences between these 3 oils?

Mobil 1 Turbo Diesel Truck 5W40

Mobil Delvac 1 5W40

Mobil Delvac 1 ESP 5W40

 

none

 

Thanks, but that's not correct!

 

Turbo Diesel Truck and Delvac 1 is the same oil. Just different packaging for it's related markets.

Not sure if ESP is any different.

Since I initially posted this, I've been snooping around on Mobil 1's site. All 3 oils have slightly different numbers. So who the heck knows. Guess I'm more curious about the Delvac 1 ESP 5W40. I saw it today at a local truck stop for $34. And ofcourse wal-mart has TDT for $22.

Wish I knew where to get Schaeffer 9000 or maybe Amsoil locally. That's why it's just easier to go to walmart. I still wonder why Royal Purple's oil is 15W40 instead of 5W40 like most other synthetic HD oils.

 

-D1 and TDT (both 5W40) They were both THE SAME WHEN THEY WERE CI4+
-D1 ESP is CJ4 5W40
-TDT (CJ4) is supposed to be slightly different than D1 ESP, but I'm not sure in what way.

 

I use Royal Purple 10W-40 in a couple of my vehicles. I get it from Summit Racing for $7.95 a qt.
