been doing this for a few months,no noticable difference in fuel milage as some claim,been using a 500 to 1 ratio, i think there is a benefit to using as the fuel injectors seem to be quieter then usual as well as the fuel pump. plugs also check out nice and clean .

 

at 500 to 1 ratio it will not harm converter or oxygen sensors.i have pulled the spark plugs and oxygen sensors out , and both are cleaner then they have ever been.

 

I have never heard of this before. What is it suppose to do? No matter what it does that stuff is not going in my motor seeing as its a 4 stroke.

 

I've heard of this for diesel, not for gas though. i use marvel mystery oil, so its probably similar to 2 stroke
