What do you know about fuel additives?

Fuel additives – are they worth the money or are they just another scam without the evidence to support the claims?

Before we get started, it’s good to remember that car manufacturers don’t support – or even recommend – using any fuel additives. They suggest that you rather stick with their manufacturer’s service schedules and keeping your car in good running order.

Fuel additives can claim to do everything from boosting the octane rating of your fuel, cleaning your engine to even removing water from the fuel. While following the manufacturer’s instructions should not lead to any damage to your fuel system and engine – we do recommend not making your own fuel additive cocktails! Tipping half a dozen bottles of additives into a tank of fuel will seriously compromise the chemical structure – and will more likely cause damage.

While many may admit that additives do in fact work – how well they work will still depend on the problem you face. For instance, newer models probably don’t require any additive cleaners – you probably won’t see any improvements as these are designed for older higher mileage cars.

Certain additives, such as the ones designed for diesel engines driven in colder climates, can be a necessity to some. Diesel can actually gel in very cold climates – making the use of these types of additives necessary to properly maintain your vehicle.

Others however, have had every test fail – these include the fuel additives that claim to boost performance or octane ratings.
