What is the difference between e10 and unleaded petrol
E10 is becoming the standard petrol grade in Great Britain, meaning E10 petrol will be available at almost all petrol stations across England, Scotland and Wales. In theory, the introduction of E10 should not increase the price of regular unleaded at the pump as it is fractionally cheaper to produce. Jump directly to the content. Sign in. All Football. A: E10 petrol will not be any more expensive than the E5 unleaded fuel it's replacing but it will increase the cost of filling up for owners of those cars that can't use E10 because they will be forced to use super unleaded fuel which will be remain E5.
A: There may be a slight reduction, but this is likely to be offset by any increase in fuel consumption. The real CO2 savings come from the crops grown for the fuel.
A: Ethanol is a form of alcohol, and the ethanol in E5 and E10 petrol is bioethanol, meaning it is a renewable fuel derived from growing and fermenting crops such as sugar, wheat and maize.
Increasing the ethanol content in petrol brings a reduction in carbon dioxide because ethanol produces less CO2 than petrol when burnt, and because the crops grown to produce it absorb CO2 from the atmosphere. In fact, it has happened on one of my own classics when a section of fuel line perished prematurely and started spewing petrol everywhere. I was lucky that it was spotted and could be made safe on the spot, but I am concerned that not everyone will be so lucky.
Any fuel damaging seals and lines that prevent fuel from reaching the hottest parts of the engine is a serious fire risk, and a potential danger to classic cars and their owners.

Q: Can my car run on E10? Q: Why is E10 already at petrol stations? Q: Will E10 petrol cost more? Q: Will my car use more fuel on E10?
Q: Does E10 reduce tailpipe CO2? Vehicle manufacturers design engines to be run on petrol with a minimum octane rating. You should always use petrol in your car that has an octane rating at least equal to that specified by the manufacturer. In turn, the majority of petrol engines designed for RON 91 are compatible with E If the manufacturer has recommended that you use premium unleaded in the vehicle, this means you should fill the tank with either RON 95 or RON Neither E10 RON 94 or regular unleaded petrol should be used in those vehicles.
High-performance or high-compression engines are designed to take advantage of the properties of high octane fuels. They have a higher compression ratio, generating higher pressure or higher temperature in the engine than regular compression engines.
To avoid pre-ignition in high-compression engines, manufacturers of these types of vehicles generally recommend the vehicle owners use a high octane petrol. These vehicles are often not E10 compatible. V8 racing supercars and some other cars run on E85, which is a high performance fuel with an octane rating of The typical family car sold in Australia has a regular compression engine, designed to use regular unleaded petrol RON Most of these cars can also use E Use our compatibility checker to see if your car can use E Blending the ethanol at this ratio increases the RON to A premium fuel must be at least RON More information about the Standards is available on the Commonwealth Department of Environment and Energy website.
At the pump, E10 is generally the cheapest petrol per litre. Fuel economy is influenced by a range of factors including how well your vehicle is maintained, how much you use the air con, road conditions and how efficiently you drive.

The story of E10 gets a bit more complicated when considering which type of petrol to use in other engines such as garden equipment mowers, whipper snippers , generators, marine engines such as outboard motors and aircraft.
Ethanol-blended fuels are generally not recommended for marine engines due to the danger of water contaminating the fuel.
