E85 is a blend of gasoline and ethanol, a type of alcohol made from grains such as corn, sugar cane, or other forms of biomass. It contains up to 85% ethanol and the rest is gasoline. E85 is known to be corrosive and can damage fuel systems, especially those built before 1994. This is because ethanol can become corrosive when mixed with water, and E85 tends to absorb water. This can lead to serious engine damage, including fuel hoses, gaskets, pumps, and seals, and can even cause irreparable damage to the engine. However, E85 has its benefits, such as a higher octane rating than gasoline and excellent cooling opportunities. To use E85, older vehicles may require an E85 conversion kit to make it optimal for E85 fuel injection.

What You'll Learn
E85 is corrosive when mixed with water
E85 is a type of fuel that contains 85% ethanol and 15% gasoline. It is designed for use in supercharged engines and offers a high octane rating of roughly 105. It also provides excellent cooling opportunities, making it ideal for certain types of superchargers.
E85 has been the subject of debate due to its potential corrosiveness. While it is true that ethanol can become corrosive when mixed with water, this is not a significant concern for standard vehicles. Ethanol does have a tendency to absorb water, but this can be mitigated by keeping the fuel tank full when the vehicle is stored. Additionally, modern vehicles (1994 and newer) are equipped with ethanol-safe fuel systems, ensuring that E85 can be used without causing damage to fuel lines, pumps, or other components.
However, for older vehicles with fuel systems built before 1994, E85 can be harmful. In these cases, it is recommended to install an E85 capability kit to ensure compatibility and prevent potential corrosion issues.
It is worth noting that ethanol is an effective cleaner and can remove deposits left by low-quality gasoline. While it does not corrode aluminum, ethanol can remove residual oil from engine components, resulting in a lack of lubrication. This can be addressed by storing the vehicle with a full tank of gasoline instead of E85 to minimize water absorption.
In summary, while E85 can be corrosive when mixed with water, this is typically not an issue for modern vehicles with ethanol-safe fuel systems. For older vehicles, taking appropriate precautions, such as installing conversion kits and maintaining full fuel tanks, can help prevent corrosion-related problems.

E85 is safe for vehicles manufactured in 1994 or later
E85 is a type of fuel that contains up to 85% ethanol and the rest is gasoline. It is a renewable, plant-based fuel that is made from fermenting plant sugars, usually from corn. E85 is a great fuel option for those looking to take advantage of its high octane rating and excellent cooling opportunities.
If you have a 1994 or newer vehicle, you don't have to worry about ethanol damaging your fuel system. However, if you have any aftermarket fuel system components, it is a good idea to double-check that they are resistant to ethanol. While ethanol is not corrosive by itself, it can become corrosive when mixed with water. Therefore, it is recommended to store your car with a full tank of gasoline instead of E85 to prevent the ethanol from absorbing water from the atmosphere.
E85 is a safe and effective option for compatible vehicles, offering high performance and reduced maintenance costs due to its cleaner-burning properties. It is also a more environmentally friendly option, as it reduces harmful emissions and supports the domestic economy by using a renewable resource produced in the United States.

E85 is not corrosive by itself
E85 is a blend of gasoline and ethanol, a type of alcohol made from grains such as corn, sugar cane, or other forms of biomass. It is also known as flex fuel and contains up to 85% ethanol. The rest is gasoline.
Ethanol by itself is not corrosive. However, it can become corrosive when mixed with water and has a tendency to absorb it. This can cause corrosion in fuel system components, especially those made of aluminium, magnesium, and some types of rubber.
Vehicles with fuel systems built in or before 1993 may experience issues with E85 as the systems were not resistant to ethanol. In 1994, the US federal government passed a law requiring that vehicles be compatible with ethanol, so engine damage caused by E85 hasn't been an issue since then.
If your vehicle is compatible with E85 or has the right tune or kit (like an eFlexFuel E85 capability kit), it can be safely used. E85 is actually safer for your engine than regular gasoline as it cleans your engine, fuel lines, and fuel injectors. It removes deposits that build up in the combustion chamber, fuel lines, and injectors.
