Was the bump in MPG just for that tank or did it continue to stay up? I've always noticed a bump in mileage for the one tank with the cleaner in it and then it drops back to normal.


Its prolly similar to the mpg boost when adding acetone which is a good cleaner within itself. Toyota sells a small can of cleaner that you add to about 1/4 tank of gas. They swear by it and I use it once a year. Its extremely concentrated and as far as I know thats how they clean the injectors short of pulling them and sending them out to be electrosonically cleaned.
