The oil is called SUPERE SPEC 5W-30 as it is just barely below a 10W-40. The base oil, if that is the corect term, is absolutely standard Mobil 1 5W-30 with a heavy duty additative package and a little group V. Here are the majors of the oil. It comes from Fairfax, VA, but it is not blended by Mobil, approved by Mobil, or may not even be known of by Mobil. It comes from a man that blends oils for HP engines with aftermarket parts and packages. I found him through my son in law that lives in Fredericksburg, Va.

There is a lot of other STUFF but they are all 1 to 4 PPM.
Mobil 1 15W-50 is a light 15W-50. I run engines that never see 3000 RPM unless something goes wrong. I trust the high detergent level and the TBN of the Mobil 1 to keep my engines clean and to overcome the contaminants, so I change it out every 3000 miles to keep it fresh.
