I have come across this product by Mobil that is a special commercial grade oil called Delvac. There are a variety of types one of which is formulated for high performance gas engines. I understand that it is expensive. but the few people I have talked to(and know about it) say it is the best oil money can buy. The diesel grade is left in vehicles for over 60,000 miles. I have written to the company to ask that they send me the wrap on it. I will post it when I get a response. Has anyone hear of this oil before?
