Bio Fuels and Ethanol (E10)
Ethanol is blended into petrol because it reduces the levels of carbon dioxide in a vehicle’s emissions, thereby helping to protect the environment.
E5 petrol has been sold for a few years. It contains anywhere from 0 to 5% bio-fuel. E10 contains up to 10% bio-fuel (not necessarily exactly 10% ). A compatibility checker can be found on the DofT’s website here: https://www.gov.uk/check-vehicle-e10-petrol . In certain circumstances, the ethanol content may cause problems with materials that have contact with the fuel. Older dispensers may have seals and gaskets that are not compatible with ethanol. Any leaks would be gradual and regular inspection of the dispensers will avoid potential issues.
Fuel Set has not been tested to determine whether it provides any level of protection against E10, given the short amount of time E10 has been in the market, and the relatively small number of cars affected. However, if you are using it in your vehicle, we can absolutely confirm that Fuel Set is compatible with E10, and can be used with E10 fuel to provide Fuel Set’s other, usual benefits.
Fuel Set was developed to “absorb” water contamination arising from condensation. E10 fuel is more hygroscopic than straight petrol (it attracts more water from the air), so this benefit is greater when Fuel Set is used – the risk of damage due to water contamination is reduced.
Fuel Set also replaces the lubricity that was lost when sulphur was removed from the fuel – important for minimising wear and tear on the engine.
Fuel Set’s cleaning action works on the entire fuel system, keeping fuel lines and injectors free from contamination and helping to prevent blocked filters. A clean engine runs smoother and more efficiently, thereby enhancing performance and giving greater economy (the older the engine, the greater the savings). A clean engine also creates fewer emissions, helping the environment and other road users.
