As of 1st September 2021, forecourts across the country have made the change from E5 to E10 fuel, in a bid to reduce CO2 emissions. But what does that mean for you and your garden machinery?
Put simply, E10 fuel is perfectly fine to use in garden machinery providing it isn't left in the machine for more than 3-4 weeks; you may also refer to the information below from specific brands, although it is generally the same across all petrol engines.
If you are unsure, you can continue using E5 fuel by purchasing super unleaded petrol from forecourts, or you can buy a fuel called Aspen which is longer-lasting (not available for shipping due to courier constraints).
E5 petrol contains up to 5% renewable ethanol whereas E10 petrol contains 10% renewable ethanol. Ethanol can be bad for your engine if left, causing corrosion to fuel components and attracting water, which subsequently can lead to all sorts of issues. These risks are increased with the jump from E5 to E10 fuel, but it is okay to use E10 fuel as long as it isn't left in machinery for more than 3-4 weeks maximum.
Briggs & Stratton Petrol Engines - E10 Fuel
Briggs & Stratton overhead-valve and side-valve engines can both use up to, and including, 10% ethanol petrol.
Always use clean, fresh, unleaded petrol with an octane rating of at least 77 for side-valve engines or at least 85 for overhead-valve engines. We recommend the use of Briggs & Stratton Fuel Fit petrol stabiliser to keep fuel fresh for up to 3 years. When using E10-95 petrol, the dosage should be increased by 25%.
Buy fuel in quantities that can be used within 30 days. This will ensure that the fuel is always fresh and that the volatility of the fuel matches the season. Do not mix petrol with oil.
NOTE: We recommend NOT using petrol containing more than 10% ethanol (E10) blend and this MUST be removed from the engine before storage. Methanol-containing petrol must also NOT be used.
