I'm posting this in the gas engine section because I'm going to run one of these oils in three gas engines. Which one has better detergency, and which one would be better for a gasser. Cost aside, which one would you guys run?

I too have used used both extensivly. The Rotella syn is really good for cold starts, but it seems to have some solubility problems. Group III and group IV oil do have solubility issues that most of the oil companies have overcome, but I think Shell has a bit further to go. I experienced this problem with the CH rated Rotella syn, but haven't tried the CI rated Rotella syn yet.quote:

I've used both extensively and really like the Delvac. In your HM application, synthetic may not be the ticket. Rotella syn is a great oil at lower temps and in a newer, high-revving or turbo engine.
Do you have proof of this ?quote:

Chevron Delo 400 can't be beat . Check the oil anaylsis' Imo Mobil 1300 places lower on uoa numbers than the common hdeo's. The Group 1 oils are self polluting crap that is not worth putting in an engine . I was a diehard syn. oil user untill I saw the results of the "hydroisomerized base oils", seems that unless real cold is involved the hdeo's hydro oils can't be beat . Although, Delvac 1 or Amsoil diesel ,marine oil would be a good choice in a synthetic with a cushion for the cold.
None of those oils are comprised entirely of group II .quote:
