Just checked their site did not see any diesel API rated oil. Just alot of stuff for Ricers and dirt bikes. Didnt even see 15w40 listed. Just 15w50 4stroke race oil. Im gonna say no take it back to em and have them redo it free of charge WITH diesel rated oil

Havent heard much about the product my thing is it should meet either the API CI or CJ4 standard for diesel engines
