Motorists desperate to save on petrol and diesel fuel costs could make dramatic savings to their bills by making a simple tweak in 2024. 

Switching from filling up with traditional petrol and diesel to alternative fuels is likely to be “more cost-effective” in a massive boost to cash-strapped road users. 

Biofuels are produced from renewable organic materials compared to the fossil fuels used in traditional compounds. 

Bioethanol is an alcohol substance made from mixing corn and sugarcane which can be used in fuel tanks.

Meanwhile, biodiesel is made using a mix of vegetable oils and animal fats compared to using traditional fuel types. 

Personal Finance expert Rebecca Bebbington of NetVoucherCodes urged road users to “explore alternative fuel options” as a simple way to save on the pennies this summer. 

However, she urged all motorists looking to take up the fuel to double check vehicles are compatible before use.

They said: “Explore alternative fuel options such as LPG (liquefied petroleum gas) or biofuels, which may be more cost-effective than traditional petrol.

“However, it's essential to ensure that your vehicle is compatible with these fuels and that there are refuelling stations available in your area.”

According to breakdown experts and car insurance specialists at the RAC, it is likely road users have been topping up with biofuels without even knowing. 

E10 fuel was introduced in the UK back in September 2021 with the compound containing up to 10 percent bioethanol compared to just five percent in the E5 formula.

They explained: “You won’t be able to fill up your car on pure bioethanol or biodiesel, but your car will run perfectly on blended unleaded and diesel as there are no compatibility issues at such low percentages.

The vast majority of vehicles are also compatible with E10 fuel as well, meaning you’ll be able to fill up on this if driving through Europe.”

However, some older vehicles are likely to be incompatible with the new compound which could be a major blow to some motorists. 

According to experts at Adrian Flux, there are two main concerns around E10 fuel with the extra ethanol likely to be corrosive.

They warned there was “more risk” of corrosion across key parts with metal, plastic and rubber in the fuel system at risk. 

Meanwhile, ethanol also absorbs water which can be a problem for vehicles which sit around for long periods of time. 

The longer a car is left inactive, the more moisture can build up and cause “serious issues” for owners.
