Mobil 1 5w-40 turbo diesel fully syntetic VS Mobil 1 15w-40 delvac 1300 - W116Lorinser - 02-09-2011
What are the Pros and Cons of each oil... and which one is better in the om617 or any diesel engine.?
i currently was using mobil 1 delvac 15w-40 1300 non syntetic and today i needed a oil change so i changed to the mobil 1 5w-40 turbo diesel full syntetic formula since it should be better in every category over the delvac 1300.
i know we have been over this 100000 times and 100000 threads but hopefully this will be the last oil thread

Leave a jug of each outside overnight, then try to pour it.
When I was in NY, I would run synthetic Rotella 5W-40 to improve cold starts. The engine spins faster when cold, builds oil pressure faster, and idles smoother.
One thing I never did and wish I had - record the time to build oil pressure from the instant the starter engages with 5W-40 and 15W-40. If you get a chance, I think it'd be interesting data to have.

Seriously, I hear you. I remember trying to top off my 300SD with a jug of 15W-40 that had been in the trunk over night when it got to -2F. It was like trying to pour honey. I had to get a plastic knife to get it out of the jug. Made me really glad I had the block heater going all night..
