Ethanol in Fuel – How can you make sure you’re protected?

UK Government is consulting on raising Ethanol proportion of petrol from 5% to 10% 

You may have heard in the news (Example: BBC News www.bbc.co.uk/news/uk-51731757) about the imminent increased use of ethanol in petrol, perhaps even seen it hyped as the fuel of the future. Produced from crops therefore producing less CO2 emissions, ethanol is rightly seen as being more sustainable.

But have you also heard of the downsides of the fuel, particularly worrying for owners of older cars and classic motorbikes?

Get the facts - And BG’s solutions:

  • Ethanol causes lost MPG, power and performance

  • Ethanol holds water

  • Ethanol causes damage and wear

Ethanol causes lost MPG, power and performance

Ethanol-containing fuel does not produce as much energy content as conventional petrol, thus contributing to lower MPG. Deposit formation is also more common with ethanol-containing fuel, altering the critical fuel/air ratio causing driveability problems like reduced throttle response.

BG Ethanol Corrosion Preventer, product code 212, contains special stabilisers that prevent fuel oxidation, gum and varnish formation. Used in ethanol-containing fuel at each fill-up, BG Ethanol Corrosion Preventer will keep the entire fuel system clean, restoring performance and fuel economy.

Ethanol holds water

Ethanol attracts, absorbs and holds water. This moisture can cause corrosion to the fuel system and erratic engine operation. And if too much water gets into fuel the ethanol and water will separate from the fuel and settle as an incombustible gloop at the bottom of the tank.

BG Ethanol Fuel System Drier, product code 281, forms a stable solution with water and gasoline allowing a certain amount of undesirable water in the tank to pass harmlessly through the fuel system, without affecting the combustion process.

Ethanol causes damage and wear

Ethanol is a mildly acidic molecule, which accelerates the corrosion process on components found in the fuel system. Older and classic cars are particularly at risk because they contain more at-risk fuel system components made of zinc and galvanised materials, brass, copper, aluminium, resins etc.

Ethanol destabilises fuel and increases its tendency to oxidize and degrade. These contaminants when formed can cause filter plugging and injector fouling, which can interrupt the fuel/air ratio and cause inefficient combustion.

BG Ethanol Fuel System Defender, product code 213, guards fuel systems from the damaging effects of ethanol gasoline. Especially important for owners of older cars and expensive classic motorbikes going into winter storage, it protects intake manifolds, intake ports, intake valves, and combustion chambers from the damage caused by ethanol oxidation.
