Bests & Worsts Reviews from Amazon

Man the more I read reviews on here the more I have to laugh at how stupid the world has become. The first thing you need to understand as if it wasn’t spelled out enough is that this is NOT an engine cleaning product in any way shape or form. People mentioning that it hasn’t fixed carbon buildup in their engines clearly don’t know what this is for. As it’s mixed with your fuel and sprayed through your fuel injectors into the carburetor where it literally explodes it will never ever ever be in a position to clean your engine of carbon buildup. It won’t fix a car with major mechanical issues as I get the feeling a lot of people think it will and as for gas mileage, the cleanliness of your engine (which this doesn’t fix) is the single biggest determining factor in that (crap in your engine reduces space around the pistons and the chambers and affects compression ratio etc etc). This stuffs primary function is in particular cleaning your little fuel injectors which spray fuel over the carburetor head. I have no reason to believe it doesn’t do this. Now if one of your injectors is old and faulty - no it won’t fix it. If, there is mild buildup of crap in the injector head or opening it most probably will remove it - same way draino will clean your pipes but won’t fix a broken one. Simple? Got it? In terms of what I actually felt with my car? A little extra beef in the pickup - it hasn’t turned my RAV4 into a Ferrari, but I have felt a little uptick in pickup. This would seem consistent with some freshly cleaned fuel injectors probably being a fraction more efficient with their job of spraying fuel. So for goodness sake don’t read and believe the jilted claims of people here pissed off that a $20 bottle of refined fuel hasn’t fixed 2Gs worth of engine issues. This stuff is fine and some regular use will stop you ever having to fork out $250 for a mechanic to clean your fuel injectors if they ever got so gunked up. Cheers.
