So I've been collecting the left over 1/2 quarts of oil after every change. Various brands....Castrol Syn Blend, Valvoline, Formula Shell, AAP full Syn, Mobil 5000, Amsoil XL, half bottle of LubroMoly, etc...
SHook the heck out of the bottle to mix it all up and poured it into the MX-5 this weekend for my OCI. No complaints and runs super smooth. Boy that LubroMoly turns it all a charcoal color. But I figure a good 3k run of this mix will do just fine, if not longer.
