seems to be about $5-6/qt so the same neighborhood as T6. I did tell him that Blackstone will give him a test kit if he wants to find out how well it is really doing.
apparently a lot of the stock car racers are running it in their high fallutin engines
a brief google didnt turn up any lab work on the stuff but someone has probably done it.
I am on the way out to the garage to swap T6 into my Adventure in place of the M1 I put in in june.
Never hurts to check new stuff out, but I doubt many, if any, of us has had an engine fail, much less be able to pin it o a certain oil.
