E10 Fuel

E10 Fuel

During summer 2021, the standard (95 octane) petrol grade in the UK will become E10. In Northern Ireland, this will happen in early 2022. E10 petrol contains up to 10% renewable ethanol, which will help to reduce carbon dioxide (CO2) emissions associated with petrol vehicles and tackle climate change.

 

Is the new E10 fuel suitable for my Yamaha?
Yes - for Yamaha motorcycles (incl. mopeds and ATVs) built after 1990
Yes - for Yamaha outboards and WaveRunners built after 2003

 

E10 petrol has a number of negative side effects that require extra attention:

  • Aging of the fuel - The addition of ethanol in fuel means that the fuel quality deteriorates after only several months.
  • Contamination of the fuel system - Ethanol is a solvent which can attack certain material compositions (rubber and plastics) of the fuel system, causing contamination.
  • Damage to fuel hoses - Due to the solvent properties of ethanol, petrol hoses can become porous and even leak as they age and through exposure to ethanol in fuel.
  • Attracting water - Ethanol is hydroscopic and will attract moisture/water to the fuel it is blended with, which will reduce the quality of the gasoline and can lead to corrosion if fuel components.

 

If you own a Yamaha motorcycle (incl. mopeds and ATVs) built before 1990 or a Yamaha outboard motor/WaveRunner built before 2003, it is recommended to only use ethanol-free ‘Super’ grade petrol e.g. Shell V-Power, BP Ultimate, Esso Synergy Supreme+ 99, Texaco Supreme and Total Excellium or equivalent, or fuels with a min. 95 octane where higher octane fuels are not available*.

*Due to labelling regulations, ’Super’ fuels will be labelled E5, even if the octane of the fuel is higher. Please check with the fuel supplier for specific information regarding their fuel products.

To compensate for the negative side effects of ethanol, please consult your Owner’s Manual in relation to care and storage guidance specific to your Yamaha.

Yamaha also recommends regularly using a quality ‘fuel system cleaner’ to maintain performance of your fuel system and a ‘fuel stabiliser’ when storing your Yamaha for any period of time, to prevent fuel deterioration. Where practical, remove fuel altogether from the fuel tank when storing for extended periods of time.
