Can Fuel Additives Improve Gas Mileage?
Gas additives on older cars may help improve gas mileage and save gas. If your fuel injectors are clogged or a needle valve has tarnish in a carborator fuel additives help keep this from getting restricted or blocked. Remember most good quality gasolines have additives for this purpose. I have found that adding a bottle of a good fuel injector cleaner about every 2 to 3 thousand miles does help keep things running better and keep you gas mileage at optimal levels. I suspect that it may also extend the life of your fuel injectors or service intervals. Again when adding anything to your gasoline check the owners manual first.
