Fuel additives - are they worthwhile?

Preventative maintenance can save you a lot of dough in the long term, but it means spending before you really have to – which is why so few of us do it.

The tactic can be especially useful if you’ve got an old car because there are all sorts of areas that are bound to have worn – possibly to the point where they’re dangerous and/or major expenditure will be necessary to put things right. 

One of the areas where you can save cash is by putting a fuel additive into your car’s engine

One of the areas where you can save cash is by putting a fuel additive into your car’s engine, which is bound to be chock-full of contaminants that have built up, leading to power loss, poor running and increased fuel consumption.

You can buy products for petrol and diesel engines, for £6-15 per treatment. Capable of removing deposits in fuel injectors, leading to greater engine efficiency, it should prove to be money well spent.

There are various players in the market, including Redex, Comma and Wynns, along with STP. Each offers an array of potions that you simply pour into your fuel tank when you fill up. The additive mixes with the fuel and is drawn through the system, cleaning as it goes. Add one of these bottles of liquid magic a couple of times each year and you should have an engine that runs much more cleanly and should pass the MoT emissions check more easily as a result.
