hi dailydriver, i love this stuff extrememly high quality and its not a mos2 like lubromoly which i would never use in my engines.. i already use redline/motul oils i did noticed an inc in hp and cooler engine but i use so many things that make my engine smooth and operate with less internal drag in combination.etc. stainless steel oil filter,red line/motul,cat back exhaust,cai,or just a k&n filter,etc.etc. and most of all good overall maintenance i feel extremely comfortable that iam getting the advantages the pros use for more hp friction reduction..i base this on the nhra mile high drag races , asked and saw, in the pits found this additive the best out there..its not a additive one can buy at the store...give it a try!! let me know what you think.this mixes nicely...
