bemywhip I'll put money on it that you've never read a UOA in your life, in fact you have no idea what a UOA is? And yes I did own Krap & Nasty, it was on the car when purchased. It went in the bin where all Krap & Nasty should be unless your using them on a racing engine that's rebuilt regularly which is what they were originally designed for. They sure don't belong on a street engine!
