Hello,
Quick question on your motor oil. Why are your motor oils still only API SL certified and not the current SN?
Thank you
RP REP"
Good Afternoon,
We retained the SL license on our street oils because the API SM required a reduction in anti-wear additive. We are a performance oil company and did not agree with the ham-fisted way in which emissions equipment protection was handled. However, because of market demand, we will be releasing API SN oils this summer that will be a warranty compliant product line of engine oils.
Thanks for inquiring about Royal Purple and have a great day!
Best Regards,
