"Brad Penn won't tell you how it works, but this oil doesn't degrade when your running race fuels and methanol as badly as conventional oil. It's also easy to tell when it is worn out because the oil fades from GREEN to brown, or black if your slacking on your oil changes. "
This is true as well....Its a great " Idiot Light " fior those of us that need to be TOLD to change our oil.
Ive run it in bot the Thing and the bus and have been greated with much better starting and running conditions in the cold - i will continue to run it. I just need someone in boise to freeking stock it cause shipping adds another 25 bucks
