Gasoline engines are among the most common engine types out there. From cars, to motorcycles, to even lawn mowers and scooters – gasoline engines are practically everywhere. They are typically used in a lot of engine types you see due to their so-so air quality that is okay on the budget.

A fuel system may sometimes run into problems. For instance, carbon deposits, gum and varnish may accumulate and this can take its toll on your overall fuel economy. Because of this, less fuel will be used by the engine. This is most common as a problem for older car models and those engines that are constantly used on the go for a lot of instances.

The carburetor is a vital part of the fuel system. Without proper maintenance, you can have less fuel efficiency every time you gas up. Clogging inside the carburetor can cause bad startups and stalling of the engine. This will definitely be a bad day for your engine if you do not clean up the carburetor and the nearby engine parts.

A clean carburetor will save you dollars in fuel and in maintenance. In fact, if you dissolve the entire residue such as carbon, gum and varnish, you will get more fuel flowing into the system and you will no longer have to waste money on fuel and when it comes to maintaining your carburetor and fuel system parts as well as other engine parts and the whole system.

Carburetor cleaners can also help clean up other fuel system and engine parts. Like we mentioned above, carburetors are mostly made of the same stuff as other parts of the engine and of the fuel system and this is why most people will definitely use a carburetor cleaner to clean other parts such as the fuel injector and other parts of the system and engine, as long as it is made with metal that is unpainted.

The carburetor cleaner should be friendly to oxygen sensors and similar parts. Majority of the formulations for most carburetor cleaner will be safe to use on the said engine and fuel system parts, so you do not need to worry. This is only a concern for most high-end and newer car models.

The carburetor cleaner should potentially reduce your engine’s emissions and improve horsepower. The purpose of any carburetor cleaner is to prevent your car or engine to make emissions and also improve the performance of your engine in the long run.
