New E10 fuel. Is there a cause for concern?

Published 11th May 2023Read Time 16 min

E10 will replace E5 in Ireland from July 1st - but what does this mean for you?

The introduction of E10 fuel is underway, and it will see the removal of E5 fuel from forecourts from July 1st. E10 petrol is already used across much of the developed world, including Europe, the US and Australia; E10 is the fuel used to test a car's performance and emissions since 2016.

E10 petrol is a fuel that may contain up to 10% ethanol by volume, the specifications for which were introduced by the European Union’s Fuel Quality Directive on 1 January 2011.

For the vast majority of people, there is no cause for concern as most cars on Irish roads will run on E10 fuel with no cause for concern. For the vast majority of people, even most older cars, there is nothing to worry about. Most cars produced in the last 10-15 years won’t have any issue running E10 fuel without any difficulties. None, nothing, All is fine. Nothing to see here.

There are a small number of cars that aren’t recommended to use the fuel, a list of which is outlined below. (Source ACEA: The European Automobile Manufacturers' Association).

If your car is listed below, don’t worry. Your car will run on E10, and in most cases, currently, the blend of E10 is more like E5.5, as to qualify for E10, it has to be over 5.5% ethanol. You might have to monitor some components at servicing time closely. If you have a classic car, you need to be more careful.

Ethanol is hygroscopic, which means that it absorbs water from the atmosphere. And that water, in turn, can find its way into your car. It can lead to condensation in fuel tanks, fuel lines and carburettors and cause corrosion in brass, copper, lead, tin and zinc components.

Ethanol is also a solvent it can eat through rubber, plastic and fibreglass, so hoses and seals are likely to perish more quickly because of the higher concentration of ethanol in E10. For now, classic car owners are advised to potentially look at replacing fuel lines and other components that might suffer through prolonged use of E10. Users of older motorbikes should also be cautious.

There are a number of additives on the market too. We can’t fully speak of the efficacy of these, but brands like Wynn’s offer an E10 protector, on sale locally in Halfords which promises to protect older engines from any negative effects of E10.

Can I still get E5 Fuel for my lawnmower?

Not after July 1st. It remains unclear whether other equipment, such as lawnmowers, will run well on E10, and with no E5 on sale from July 1st, petrol lawnmower owners might have issues down the line. However, don’t leave fuel in the tank; you should alleviate many potential risks.

Should you be worried?

So is there a huge cause for concern? We would say no. If you service your car regularly and don’t leave it idle for long periods of time, even cars which haven’t been homologated for E10 should be fine. If you have a classic car or motorbike that you do intend to leave idle for longer spells, draining the fuel tanks could be advisable before storing.

Initially, the blends of E10 on sale are likely to be quite low in ethanol anyway. If you have a concern, speak to your dealer or technician, who will advise.
