iam running mopar diesel oil in my car that was suggested by my engine guy(he does mopars for people all over the world and knows what he's talking about) and i was just wondering if anyone else is?
I can't comment on the mopar diesel oil but I and alot of the guys are or were using Shell Rotella T cuss it had zinc in it which the flat tappet cams need. Problem is that as more diesels are going to roller cams and lifters Shell is backing down the zinc because it's a pollutant. I've started using Mobil 1 in the 383 with a can of EOS (from the GM dealer in town) thrown in. The EOS is for engine breakin and supposedly contains a high degree of Zinc. Oh yea almost forgot, they are starting to put catalitic converters on diesels an apparently zinc kills them.
