Many car owners have been left wondering if their car is performing as it
should after it was revealed Volkswagen had been cheating emissions tests with
some of its cars. One of the simplest ways to change your car’s performance,
emissions and economy is to use a fuel additive, but how do they work and are
they effective?
Much of the benefit potentially offered by fuel additives depends on the
condition of your car’s engine. An engine in good working order and properly
serviced simply doesn’t need a fuel additive. The best route here is to use a
premium fuel, either for petrol or diesel engines, to give the motor a bit more
pep, though this will increase your fuel bill.
So, fuel additives are best for high mileage worn engines? Well, not really
as these engines will not be working very efficiently to begin with, and putting
a small amount of liquid additive into the tank will do little to improve
matters.
Most additives claim to help remove built-up carbon and dirt deposits from
the engine’s moving parts. However, independent evidence suggests most additives
do not work and can actually reduce engine performance by up to 2%. The only way
this type of additive would work fully is if you used it from when the car was
brand new and continued all through its life. Again, the cost of this would add
up and it would be cheaper simply to use a premium fuel instead.
Other fuel additives claim to boost the amount of octane in the fuel and give
more performance as a result of creating a bigger bang when the fuel goes into
the engine’s cylinders. Again, independent tests show most additives of this
type do nothing to affect your car’s performance and some worsen performance,
economy and emissions as the engine has to do more work to burn and expel the
extra chemicals being poured into it.
There are some additives that do what they claim, but you have to be very
specific about which ones you choose. Selecting a cheap additive that makes all
sorts of claims is likely to yield no benefit. Choose an additive that says it
will clean the fuel injectors or fuel system and you have more chance of
noticing a small improvement. These additives have very strong chemicals in them
to remove dirt from the fuel system or injectors, though it must be remembered,
they are not a substitute for maintaining your car properly and replacing worn
parts.
If you still think a fuel additive might help, follow the instructions
closely. Do not put too much into the fuel tank and only pour in the additive
when you are filling the tank.
However, the best bet for improving your car’s engine performance is to
give it a full service and stick to the recommended service schedule.
