Fuel injection cleaner or fuel injector cleaner is one of those often missed steps in tuneups for cars, trucks, and other automobiles. Because of the fact that it can get a little pricey to disassemble and replace or clean a fuel injection system, it's often glossed over during regular tuneups.
Clean fuel injectors are a definite must in the way of fuel economy, emissions, and peak engine performance. When fuel injectors are dirty, they can't deliver the correct spray required for combustion, and as a result, fuel economy and engine performance suffers. This, in the long run, can be costly or can even begin to cause symptoms like a rough idle or misfires. That's why I heavily recommend fuel injection cleaner. The reason I recommend fuel injector cleaner is because it's one of those simple things a person can do without having to replace any parts or any under the hood work.
Normally in a tuneup, lots of things get replaced, things like spark plugs, distributor caps, belts, and fluids. But with fuel injectors, running an additive through a tank of gas every once in awhile will definitely do the trick. Over time, all fuel injectors will become clogged. This happens because the deposits come from the gasoline itself.
There are a wide variety of fuel injection cleaners, one of the most common being gasoline itself! Cheap gasoline is often lacking in the additives that breakdown clogging and, over the long haul, can cost you more money than it saves. The best tip for keeping your injectors clean is to not buy cheap gas. This however, is only a preventative measure. My guess is that for people reading this article, it's because your fuel injectors are already partially clogged and are causing problems to your engine performance. If that's the case, then you still have quite a few options. There are many cheap fuel injection cleaners that you can add to your gasoline which will act like drano on a sink pipe and will dissolve many of the clogs in your injectors. When used semi-regularly (once every few months) it will keep your injectors nice and clean.
But this may not be enough for some engines. Older engines already experiencing heavy problems may need a bigger hand. To do this, you might actually need a fuel injection cleaner kit that lets you disassemble the fuel injection system and clean it. This, however, isn't always a possibility, and some fuel injectors are delicate and difficult to tamper with. Before trying this, I would definitely recommend running a bottle of fuel injection cleaner additive or two through a tank of gas and see if that helps at all. It's cheap and effective. There's your money saving tip of the day!
