It's a racing oil that is suitable for Methanol and Nitromethane use. It is SG because of the high amounts of Zinc and Phosphorus in the formulation. It is a good product.

That's what my buddy's son uses in his drag machine. He has about 20 cases of it at the beginning of the season. You always get a bunch of left overs from the methanol in the sump. I don't know how long it would last in street use [I dont know]
