Verified Easy to use, not sure if it...did anything at all Used this on my 2014 SHO with 75k miles on it. Easy to install, minus having to drive at highway speed for 30 minutes after applying. I didn't notice any change at all. No smoke, no smells, no MPG gain, no power gain (I already have a tune from Unleashed, so, whatever gains this stuff might give would be overshadowed anyways), so improved idle or idle smoothness, etc. I have no idea if this worked, or did anything at all, BUT, it didnt cause any problems (I drove for 5 hours a few days after using it). For the price, if it "revived" anything or will help protect the engine, even if there were no immediate tangible benefits, its fine with me.
