Are fuel additives worth your time and money?

There is a very good market for after-market automotive fuel additives, but there are varying opinions as to whether such products are necessary. When one considers that most modern gasoline has detergents and some other additives to help clean away engine deposits, spending extra money on additional fuel additives may seem less than essential. Answer Bag sums up the general consensus on fuel additive validity. For every person who gets the products that you add to the fuel tank, there are others who suggest that fuel additives are unnecessary.

What is really happening when you use additives

Fuel additives say that they really do clean deposits from your car’s gas. However, any MPG boosts tend to be minimal; they simply get your car back to where it is intended to be in the first place in terms of miles per gallon. Using the proper octane rating inside your gasoline and keeping up with general maintenance might very well achieve the exact same effect. Octane-enhancer solutions, pills, magnets, additional filters and more sound very scientifically sound, but the biggest gain to vehicle performance may actually come from that newfound lightness as part of your wallet after purchasing such products, suggests

Don’t believe the job could be done by your gas?

As outlined by a couple of different sources, a modern gasoline can contain any number of the following fuel additives, already in the mix:

  • Antioxidants – To prevent oxidation
  • Metal deactivators – To inhibit copper, which can rapidly promote oxidation
  • Corrosion inhibitors – There to prevent corrosion caused by water condensation
  • Anti-icing additives – Just because frozen fuel doesn't burn
  • Anti-wear additives – Possibly to lessen wear and tear on cylinders and pistons.
  • Deposit-modifying additives – To change the composition of engine deposits for easier disposal

Don’t make an effort to confuse your oxygen sensor

Your engine's oxygen sensor (initially called a "Lambda Sensor" when they first appeared in European fuel-injected cars) is intended to monitor the fuel-oxygen mixture so that emissions are properly regulated. Fuel additives can change the expected exhaust gas composition and will then confuse the sensor. If the oxygen sensor goes dead, your automobile will burn much more gas (the opposite of the desired effect from fuel additives) and eventually damage the catalytic converter. That amounts to major repair dollars.

And you also would rather not think about repairs when paying down auto loans for people with bad credit!
