: I just hear of this oil that is made by Mobil. It is called Delvac. It is a commercial grade oil that comes in a variety of different grades, one of which is a oil for high performance gas engines. The few people i have talked to about it(that even know about it) say it is the best oil money can buy. The grade for diesel engines go over 60,000 miles between changes(granted a much much larger capacity). I have written the compnay and will post there reply when I recieve it. Has anyone heard of this oil before? I am thinking about using it.
