Mobil1 15w-50w, anybody out there use this stuff? Good, Bad...? I know it's great in small diesel engines but have never tried in a stroke.

Try Mobil Turbo diesel I think you will be better off.

i used Mobil delvac 15-40 for my oil change today...

Joe for a Dino delvac Rocks!!

If I used Dino thats what would be in my truck

Delvac is good stuff, we use that in all of our equipment at work, in every branch across the country

Yup people will argue with me until they are blue in the face that rotella is the best but it's just not the truth. Both Delo and delvac are better products

I can't say that there is anything wrong with Rotella, but I have been using Mobil1 15W-50W in a cummins 4bt for the past 4 years, and the motor runs great and when changed, the oil looks real good; not sure what affect it will have in a common rail situation

I can't and won't attemp to answere that one. The 15-50 is diesel rated but it's doesn't have all of the major manufactures backing it.

I hear ya, that's why i'm apprehensive
