used it in a jeep cj-7 with close to 100K miles on it ONCE! the next week it threw a Con Rod through the oil pan. Coincidence maybe or maybe not, but the motor did run better for that week, IMHO i belive that it maybe restored some compression and created more internal pressure on already old and weakened parts that could not handle the increase in compression/power.

I will never use it again in any vehicle, and definitly would advise against putting it into a Turbo! the clearances are so tight is there really room for bits of teflon?
