Subject: Re: Carb/Fuel Injector Cleaner?


The water method suggested by others is a good method for cleaning deposits from the valves, but it doesn't do anything for the fuel injectors (as your post requested). BTW, American Motors Corp did the original testing about 30 or 40 years ago, and they found that plain tap water (it doesn't need to be carbonated) was more effective at cleaning the valves than any of the special preparations that were available. For the fuel injectors - and a car of that age and mileage likely has injectors that need cleaning if they haven't yet been replaced - an additive to the fuel would be most effective. I used to have a system that would allow the car to run on a 12 fl. oz. can of Gumout to perform the cleaning, but that only works with mechanical fuel pumps and carbureted engines. I got somewhat improved performance and fuel economy after cleaning the injectors in my 9000 when it had about 120K miles on it. In my area, certain gas stations sell "E-85" fuel, which is 85% ethanol and 15% gasoline. It is an alternate fuel for certain cars that are designed to operate on this mixture - the most readily available one is the Ford Taurus. Ethanol also happens to be the main ingredient in most fuel injector cleaners available in the store for $5 a pint. E-85 typically costs about the same as regular unleaded (or less in some places). I used 2 gallons in a nearly full tank. It is best to do this when the weather is warm because ethanol doesn't vaporize as well as gasoline and may cause problems with the engine being able to idle properly in cold weather. Don't use it too often, as it is more likely to corrode some metal parts and soften some rubber and plastic parts than regular gasoline. And don't pump it directly into your tank, use a one or two gallon fuel jug. This way you can (somewhat) accurately measure how much you put in, and you don't risk the station attendant turning off the pump and telling you that you can't use that fuel in your car. If they ask, you can tell them you plan to use it in your lawn mower (it works well there too). I tried this and it worked well for me. YMMV.
