Do Fuel Saving Devices For Cars Work?

There are many fuel saving devices for cars which claim to boost mileage efficiency. These devices
have been around for many years, and often rear their heads again every time there is a spike in fuel
prices. Many drivers are left wondering if fuel saving devices for cars really work, and how they can
save them money.

Unfortunately, a lot of these fuel saving devices for vehicles don’t do what they promise on the box,
and some can actually damage engines and hurt mileage. The good news is, this isn’t the case for all
of these devices; you just need to choose the right options for your vehicle.

Fuel Saving Devices For Cars: What Works And What Doesn’t?

The best way to choose fuel saving devices that will actually work is to have an understanding of the
facts behind these mileage-boosting claims. Fuel saving devices for cars generally come under one of
three categories

• Fuel Burn Enhancers: This includes fuel line magnets, fuel and engine ionizers and metallic
  catalysts which are inserted into the tank. They often use electromagnetic fields or ionic
  corona generators to try and change the molecular structure of fuel. Manufacturers claim
  this makes fuel burn faster or more completely.
  The truth is, even if they do improve fuel burn, it would be in such small amounts that the
  impact on mileage would be small./
• Airflow Manipulators: The flow of air into the engine greatly impacts the efficiency of the
  vehicle. Most new cars allow a precise amount of air into the engine, which is mixed with
  fuel vapour and then flows into cylinders for combustion. Some fuel saving devices for cars
  claim to enhance this process. They attempt to improve the mixing of air and fuel; however,
  they often end up disrupting airflow.
  In modern engines, the car may compensate for this by injecting more fuel to adjust the fuel
  flow.
• Fuel Or Oil Additives: There are thousands of options for additives, fuel system cleaners and
  octane boosters. Some claim to clean the carbon deposits in the engine, and others say they
  will enhance oil or fuel performance using chemical reactions. Because there are so many
  products in this category of fuel saving devices for cars, it is impossible to say if they all work
  or not.

Some do clean internal engine parts, whilst others may have additives that are harmful to
engine sensors.

So, if you’re looking to improve your fuel efficiency, it may be best to concentrate on your driving
style and ensuring regular, routine maintenance to keep your vehicle in tip-top condition to help
increase your fuel efficiency.
