LOLOL that will work,
but I am gonna try them, I am in the yota so much and blah blah, every little thing now I cna tell
and your gonna find this not true,
but out of havoline, castrol, royal purple,penzoil, valvoline, and guess what? walmart synthetic brand, the walmart brand lasted the longest before turning color and chnging the fuel mileage and the mpg's were highest with the wally world stuff, with the exceptionof mobil 1, mobil 1 lasted the same, but gave .3 tenths better mileage,
I know it sounds nutts, but I jsut put it back in over castrol, (filter change and complete drain every time) and the mileag is back up .7 tenths over what the castrol was, penzoil gave the worst results
