Adam:

I've never heard of running it in the crankcase.  Doesn't seem to be a
great place to put it.  I have used it in the gas tank before.  An old
racer friend of mine told me it was what they used to call "top oil" and
was used in the fuel to lube and clean the valve train and the fuel
delivery system.  It will quiet noisy lifters I have used it in many cars
(Audi included) to quiet noisy tappets and valves. Any other BTDT out there?
