Kroil is made by Kano Laboratories here in Nashville, Tennessee. Their biggest customer is the US government. 35 years ago when I was in the USAF, every air base worldwide had Kroil on stock in the supply system. Good stuff! It will creep past rusted-up piston rings and end up in the crankcase after being poured into the top of a cylinder, in just a few days' time.
