I also like the engine scrup.
Is the inside of your motor dirty? Most likely! Some people will tell you the only way to clean your motor is to tear it down and rebuild it. This is no good!!! KaleCoAuto internals cleaner is a special combination of iron, graphite, and copper shrapnel of assorted sizes that work to sand and polish the inside of your motor! Add 2oz per quart of oil in your car. New engine clean shrapnel should be used at every oil change! Bottle includes pouring mechanism. Comes in 16oz packages. Do not injest. Contact a physician immediately if injested, do not induce vomiting.
