Works great
My 2011 RAV4 has 380,000 miles on it and was throwing a code that was likely a catalytic converter as it wasnโt resolved after replacing the O2 sensors. After three bottles of this product (1 whole bottle in the first tank and 1-2 oz per tank thereafter) the check engine light has gone off and stayed off for 500 miles or so. It is also running smoother and the mpg is back where it should be. I definitely recommend this product.

This gasoline additive actually worked
Definitely noticed a difference in idling and smoothness of acceleration after using one bottle in 2001 Chevrolet 5.3L Suburban with high miles. Have tried other additives with no noticeable difference so Shaeffer's additive must be doing something positive.

Improved old riding mower
Tried it in one of our old riding lawnmowers, that had been hard to start and ran rough. Just to see if it would do anything. Added 6 ounces to the fuel and the engine ran like new. Blown away with the result.

Works great! Maybe to good
Schaeffer has the best products, I swear by them. This made my girlfriends car idle a bit smoother no noticeable difference in mpg but I only did a one time treatment. I also used it in my work car that was on its last leg. The difference was noticeable almost immediately about a quarter of the way through the tank of gas it was running like a top. About half way through the tank though it must have caused some gunk to break loose and it clogged and injector. So maybe it works to good!

Pretty good but no Amsoil
I figured I would give it a try and see what all the hype is about and I'm surprisingly it's just hype I'm going to stick with Amsoil
