It is alot better than any kind of treatment.

I usally get 22 mpg average or less with A/C system on with any gas treatment or even octane booster. I talked to part store which is better for me when I go on a trip plan to drive around 1,500 miles. which I also stated I get poor gas mileage. Part store specialist says get this Lucas Oil fuel treatment, and you will get get big increase. So I bought a bottle, I was unsure it will help or not. Poured in there w/ full tank of gas. The first fill up does all the work cleaning out your injectors, fuel system and engine. The 2nd time I put in full tank of gas after I used fuel treatment(no treatment added), I already rose to 30 mpg with A/C on(29mpg hilly areas). I was amazed, really your product saved me alot money on gas on return trip home. Only paid 60 dollars (high gas prices avg 2.50 per gallon) for 900 miles. Next trip I plan to use fuel treatment again. Thanks to Lucas oil!!
