Bear in mind that simple physics are involved in the fuel system. There is no magic juice that will change everything and allow for way-increased performance, shy of radical changes to the entire system.
If it were as easy as a simple additive, we'd already be there and doing that. Especially with the advent of $4.00 gas.
Over my years in the trades, I've seen all sorts of weird stuff come and go -- and so far, NOTHING has made a difference. Acetone, gives some increases for the first few tanks -- I predict that it is merely cleaning the fuel system and after that, gains go away. Same for other additives.
Run a good grade of fuel. Run 87 octane (more power in 87 than in 97!). Keep the system cleaned and tuned. Live with it, or spend a lot of money modifying via head porting, increased compression, race fuel, timing and fuel curves, larger injectors, etc., etc., etc., none of which will give you increased economy.
the fitch fuel catalyst works! just not the way they claim.............and really doesnt work . it is a glorified filter and like the last poast states it helps for about 4 or 5 tanks. it is a little rinky filter that cleans your fuel system a little bit from beyond the point it is placed in the system and since you place it under the hood doesnt do a whole lot. if you want twice the effects of the catalyst at a fraction of the price go to autozone get 3 or 4 bottles of fuel treatment such and add it the next few tanks. now with the 200 bucks i just saved you get a tune caz thats were the bang for buck is at.
