Scored a major good deal on some mobil delvac 1 5w40. $27 a gallon plus the $13 mail in rebate, $14 for a top quality oil is a win in my book. Anyways on the website it says that it can be used in mixed fleet gas vehicles. Since I use this vehicle all the time pulling stuff and basically driving It like I stole it, I figured this stuff cant hurt. Its whole life has been on EP 5W-30 with 10k-15k OCI. First thing I immediately noticed was the startup lifter noise dissipated and is now non existent. To me it even seems to idle a little smoother.....
So since this is a robust top notch diesel oil, can I run it at the same OCI as when I was using the EP?
