Engine additives firm Fueltone Pro has reported further increases in the use of petrol and diesel additives, as a sustained rise in the cost of fuel continues.
Fuel prices at forecourts across the country remain high, with further increases expected due to a reduction in supply and the weaker pound affecting import costs.
Increased fuel costs are driven by high global oil prices, but also that petrol is being “overpriced” by retailers, the RAC has suggests.
This culminated in a fourth consecutive month of rises in June, equating to almost £90 to fill up a typical 55-litre diesel family car. That is £4 more expensive than in August and the highest price since April this year.
Filling a petrol car with a 55-litre tank will cost £86 on average, the highest price since December 2022.
It is claimed additives can increase a car’s MPG by keeping the engine clean, meaning the engine burns the fuel for longer and at a higher temperature, resulting in an increase in power for every millilitre of fuel that the vehicle consumes.
Some products, such as those sold by Fueltone Pro, can deliver up to five percent increase in vehicle fuel efficiency, show independent tests.
