By Discount Motor City, the Best in Used Car Dealerships, Surrey

We have probably all wondered if fuel additives are a positive thing for a used car, or whether they are just hype.  Do they really help with fuel economy, or make your used car run smoother and cleaner?

Snake Oil for Used Cars?

Are fuel additives the proverbial “snake oil,” that is mostly useless for the stated purpose?  Or, is it really worth the money and work as advertised?

Manufacturers of the fuel additives make claims of their product reducing friction by coating moving parts with synthetics, eliminating deposits making for a much cleaner operating engine, and improving fuel economy.  They profess to have studies that support their claims, but third-party evaluations are mostly non-existent.

The Best Case for Used Cars

Buy a bottle of fuel additive and put it in your gas tank; the best-case scenario is that it does nothing at all.  The synthetic blend makes it to your crankcase at the bottom end of your engine and evaporates.  The problem most of us face, is we are hugely optimistic when having spent money on something.  Do most people go put hard-earned cash on the table to buy something and then follow that with trash talk?  Not likely, and that is fine if that is their opinion.

The Worst Case for Used Cars

The worst case is that a fuel additive could actually harm your engine.  There are chemical mixes that could be harmful, damaging electronics, or clogging critical parts. In most cases, other than in a few specific examples, fuel additives may be more risk than they are worth. 

Specific Examples Where Fuel Additives Help

  • In classic cars with cast iron blocks, lead substitutes can provide lubricating qualities that today’s unleaded fuel cannot offer.
  • Using a fuel stabilizer if your vehicle will not be used for several months will help stabilize the fuel in the tank.
  • In diesel engines, operating in freezing temperatures, a fuel additive to prevent fuel gelling will help keep the engine running.
  • If you want to clean your engine, a good fuel injector cleaner can be used, which may improve your used car’s performance.
