FYI...Royal Purple is a great Syn oil but lacks API Certification. Your car will generally not "blow-up" just becuase an oil isn't API "certified".
True, but in GF-5 non API certified oil is exempted from some tests (deposit test) so for HM oil, it may be better to use non API since the additive will burn and help to seal the oil leakage. WRONG ?
Burn to seal the leak? Say what?
