What Role Do Car Fuel Additives Play and Are They Effective?

Fuel additives allege that they assist in improving your car’s performance, fuel economy or both, but is this true? Fuel additives have a mall market but if the different manufacturers claim that their magic potions are to be believed, it means wheezy old engines can be transformed to a top performer. Pouring the right additives would do the trick.

Fuel additives are manufactured for purposes of unclogging blocked injectors, improving ignition efficiency, and reducing or preventing chances of knocking, as well as enabling the engine to run more smoothly than before. The fuel supplements are available for both engine types (petrol or diesel) and are poured straight into the fuel tank when it is full. It gets diluted by fuel and flows along the fuel lines, pump, carburetor or injector and lastly the combustion chamber, treating all of them in the process. The additives seem to work perfectly for older cars (10 years plus) or those vehicles that have not been regularly maintained or neglected.

Additive Types

A number of fuel additives are available and they serve different functions depending on the engine type as well as those made for older car versions that require leaded fuel. Lead supplements provide old car owners with a lifeline, which suffers poor power delivery and extreme valve wear. People living in cold areas can purchase additives that stop diesel from congealing which may cause blockages. If you will park your car for long, there is an additive that can assist you in preserving the fuel to enable the car to start well when you return. Performing an engine flush can also help in starting a car that has not run for a long time.

Efficiency

As much as these additives offer assistance in some situations, it is advisable to steer clear of the ones that claim they help in improving fuel economy. The savings you make on the fuel will be wiped out by the price of the fuel additive for sure. Independent tests have also shown that these supplements hardly deliver on their promises.

Substitutes

If your car is less than 10 years old and you maintain it well, there is no need for these fuel additives. The vehicle’s fuel system and car electronics are optimized to offer the best efficiency and performance mix. If these fuel additives are great, then why do car makers not recommend them and why are they not commonly sold in petrol stations?
