Not sure on what is used for base oils for diesel oil but it could be Group III, IV or V base oils or any blend of those three depending what the intended use of the oil is. And the decision on what base oil(s) to use and in what ratios dictates what the additive pack will look like.
If diesel oil was the **** it would be in every Pro Stocker and Comp car running. It ain’t.
Companies like LAT and Torco make 20 plus engine oils. That’s not counting the various grades of oil.
They don’t do that because it’s a better business plan. It’s not. Each oil fits a specific application and then you narrow down the grade.
