Nowadays most major brand of gas already contain an additive like techron or its equivilent. It works good to keep injectors clean. Once injectors get dirty,the safest and most effective way to clean them is to use a product which attaches directly to the fuel rail. You pull the fuel pump relay and the car will run for a minute or so on the contents of the can which is highly concentrated. This high concentration cleans the best and also cleans intake runners,intake valves and combustion chambers. You should not use any product
other than gasoline in a fuel tank for many reasons. there are many plastic parts in tank like pumps ,sending unit circuit boards and check valves which the cleaners may damage. Also any solvents added to the tank will dissolve deposits in the tank which are not soluble in gasoline and mobilize them to move about the fuel system where they can damaGe fuel pump turbines ,clog filters and ultimatly get to the injectors you are trying to clean in the first place! Manufacturers compile data on warranty and know that dealers who were selling customers in-tank cleaners as regular maintenance items had much higher warranty repair frequency on fuel system components.

It is effective....but may harm system components especially if used in higher than recommended concentrations. A lot of technicians are not aware of this. But they do enjoy the extra revenue is produces down the road when they get to sell you a fuel pump or a sending unit.
Techron,,,20 years of using,,,In my own and custemers cars and trucks,,,,,,,only one I will recomend,,,,My self in my truck,,,every other oil change,,,12,000 miles,,,,synthectic oil,,,,custemers ,,,as often as I can get them to buy it
my mechanic says a good rule of thumb is to use a can/bottle of a good injector cleaner after every oil change and put it in when you've got 1/2 a tank of gas left and run it almost empty....it concentrates the cleaner and you get maximum benefit.
Sorry guys but I think its a waste of money. There's a web site out there that I've read stating these cleaners show no benefit or advantage for use. If you want to support your favorite racing team thats fine. All of my car/trucks/SUV's, different brnads, have never had that stuff added to them. Results: Same fuel ecomony from mile 1 to mile 100,000, same power, same performance. Exxon/Mobil fuel is all I use. I compare this to Wheel Cleaners.
All these expensive wheel/rim cleaners. If you wash your car/truck on a regular basis all those rims need is car wash soap. Nothing fancy. Dave
