According to the experts at Autocar, E10 petrol’s higher bioethanol content is corrosive to rubber parts, gaskets, seals, metals and plastics, which causes engine damage. The site adds: “E10 could dislodge deposits in older engines and fuel systems, causing blockages.

Does E10 damage your engine?
Unlike putting petrol into a diesel engine, you shouldn’t need to drain the tank. On a one-time basis, your vehicle will not suffer engine damage as a result. Prolonged use of E10 petrol in a non-compatible vehicle, however, may cause harm and is not recommended.
What are the negatives of E10?
But using E10 petrol in an incompatible vehicle will, over time, cause problems in the fuel system. Carburettor corrosion, fuel hose degradation, fuel filter blockage and damaged fuel pumps are all likely if you use E10 regularly in vehicles that shouldn’t take it.
Can E10 damage injectors?
Ethanol in gasoline has been associated with injector problems. This is most prevalent if you get a bad batch of E10 or E15 that has undergone phase separation.
How corrosive is E10?
If used over a long period E10 petrol can cause long lasting damage to non-compatible vehicles (manufactured before 2011). The ethanol content also has corrosive properties that can damage hoses, seals, metals and plastics within the engine.
What happens if you put E10 in an old car?
First: ethanol is corrosive. So with there being a higher percentage of ethanol in E10, there’s more risk of corrosion on any metal, plastic and rubber in your classic car’s fuel system. This can result in many different issues, from fully broken fuel lines to carburettor issues.
What happens if I use E10 instead of E5?
If you accidentally fill a car with E10 when it needs E5, some of the vehicle’s internal components may suffer as a result. The extra solvents in the fuel can cause damage to the fuel pumps, lines and carburettors, especially in the long term.
Is there an additive to put in E10 petrol?
Liqui Moly E10 Fuel Additive is a state-of-the-art, ash-free fuel additive for improving combustion and faster acceleration in partial load range. Specially developed to compensate loss of performance from E10 fuel and improves the vehicle acceleration and smoothness.
Does E10 fuel affect mpg?
economy varies depending on the amount of denaturant that is added to the ethanol. In general, vehicle fuel economy may decrease by about 3% when using E10”.
Is E10 fuel better than unleaded?
E10 fuel has largely replaced the old basic fuel we knew as ‘Unleaded’ and which carried an octane rating of 91RON. The key difference between E10 and unleaded is E10 is made up of 90 per cent unleaded with a blend of 10 percent ethanol content.
Does E10 fuel damage aluminum?
Although light, aluminium is a highly reactive metal that relies on an oxide layer for protection against its corrosion. This oxide layer occurs naturally, and the low levels of ethanol such as E10 (10% ethanol, 90% gasoline) or the 5% ethanol blend often found in Europe are usually not a problem.
Does ethanol damage fuel pumps?
Ethanol can cause several types of damage to the engine in your vehicle. Your vehicle’s fuel intake components can be damaged. In addition, ethanol can cause damage to the fuel pump in your vehicle. These repairs and replacements can range from a few hundred dollars to more than $1,000 to take care of properly.
What cars Cannot run on E10 petrol?
There are a couple of exceptions however which shouldn’t be used with E10 petrol:
- Fiat Barchetta (1.8 litre 16V)
- Fiat Bravo/Brava 182 (1.6 litre 16V)
- Fiat Doblò (1.6 litre 16V)
- Fiat Marea (1.6 litre 16V, 2.0 litre 16V)
- Fiat Multipla (1.6 litre 16V)
- Fiat Palio (1.6 litre 16V)
- Fiat Punto 188: (1.8 litre 16V)
Does super unleaded damage your engine?
It’s absolutely fine to mix unleaded and super-unleaded petrol. Whether you put a tank of super in every few times you fill up to flush through the engine, or you top up the tank with £20 of the more expensive fuel, it won’t do any damage to your engine.
Does E10 petrol affect performance?
It is believed that the higher bioethanol content in E10 petrol could dislodge deposits in older engines and fuel systems, causing blockages; it could also cause some seals, gaskets, metals and plastics to corrode.
Which petrol is best for my car?
Always refer to your vehicle manufacturer’s recommendations before filling up at the fuel station, as the type of unleaded fuel you use does matter. In a vehicle that is recommended to use regular unleaded (91) fuel – you can opt for premium 95 or 98 unleaded fuel. This will not cause any harm to your engine.
Can E10 fuel damage a catalytic converter?
Extra oxygen atom
Because ethanol molecules have an extra atom of oxygen, the system may reduce the fuel content to compensate. That would make the engine run hotter, which can damage the catalytic converter that controls emissions–making the car’s exhaust dirtier overall.
Does redex help with E10 fuel?
Redex Petrol System Cleaner is a fuel additive specially developed to reduce emissions and restore performance in your fuel system. It is compatible with E10 fuel, and our new updated formula also protects against corrosion from E10 fuel, so it can be used safely in all petrol cars.
How much less efficient is E10 than E5?
One of the key changes with E10 unleaded petrol is the difference in fuel efficiency compared to E5. Your drivers who fill up with E10 will get fewer miles per gallon due to it containing 5% more ethanol.
Which is better E5 or E10?
E5 petrol is made up of 95 per cent unleaded petrol plus 5 per cent ethanol (which is why it’s named ‘E5’). E10 petrol is much more beneficial to the environment, containing 10% ethanol and 90% regular unleaded petrol. The result of this change is that CO2 emissions from our vehicle are cut down.
What is the problem with ethanol fuel?
Ethanol is corrosive. Ethanol reacts naturally with oxygen in the air to form acidic compounds which lead to corrosion of fuel system components and engine wear. With the presence of both water and ethanol, corrosion is accelerated in all metal types.
