M1 Delvac 5W40 good in gasoline engines?

[Garry]

How does this oil perform in gasoline applications. I read somewhere that it is too high in detergents which interfere with optimum lubrication. Any thoughts would be appreciated. --Garry 01 Toyota 4Runner

Mobil Delvac 1 carries the API Service Classification SL, so it's suitable for gasoline engines. http://www.mobil.com/USA-English/Lubes/PDS/GLXXE2CVLMOMobilDelvac1_5W-40.asp Ken

Hi, yes, excellent as long as the viscosity is in the maker's recommended "basket" Regards

It does carry the SL classification, but because it's a 5W-40, it does not have the .10 max phosphorus limit that the xW-30 oils have.
