I was puttering around in the garage this morning and I was reading the labels on some oil bottles and I noticed my AMSOIL SSO 5W-30 did not bear the API starburst.
It's a simple question and there is no need for anyone to get their hackles up, regardless of whether you use their products or not, but are AMSOIL's products not API certified?
