Thank you Mr. Morgan. I also contacted Schaeffer and waiting for their email response. Can you provide me with a label showing API SN Certification? I can't find it on their website. I found one picture of the API SN oil, but it did not have the API label on the front. Maybe it is on the back?
Also, can you provide a written parts and labor warranty for the motor oils? I couldn't find that on the website either.
Also, does any Schaeffer oil list Dexos 1?
