E85 is a biofuel blend of 85% ethanol and 15% gasoline obtained from biomass sources such as corn crops, grains, and sugarcane. It is a popular, cost-effective fuel option, especially for high-horsepower engines. However, concerns have been raised about its potential to damage fuel lines and other engine components. While E85 is an effective cleaner for engines, its hydroscopic nature makes it prone to absorbing moisture, which can lead to rust and injector issues. The key factor in determining its compatibility is the vehicle's age and ethanol resistance, as older cars with non-ethanol-resistant fuel systems may be susceptible to corrosion and damage from E85.
| Characteristics | Values |
|---|---|
| E85 Damaging Fuel Lines | E85 contains up to 85% ethanol and the rest is gasoline. It can be harmful to fuel lines, fuel pumps, and other fuel system components that aren't resistant to ethanol. So if you have a 1993 or older vehicle that still has its original fuel system, you may not be able to use E85. However, since 1994, it has been US federal law that vehicles must be compatible with ethanol, so engine damage caused by E85 hasn't been an issue since then. |
| E85 as a Cleaner | E85 is an effective cleaner that can be used to clear the engine, fuel lines, and fuel injectors of deposits. It is often used instead of a fuel injector cleaner. |
| E85 Conversion Kits | E85 capability kits are available for those looking to convert to flex fuel. These kits take control of the fuel injection process and optimize it for E85. They also include an ethanol sensor that monitors the ethanol content in the fuel. |
| E85 Performance | E85 is a cost-effective and powerful fuel that can provide high performance. However, it has a higher consumption rate than regular gasoline, with a typical car burning 20-30% more fuel to match the performance of regular gasoline. |
| E85 Drawbacks | E85 has a limited history of use and is hydroscopic, attracting moisture from the air. This can lead to water buildup in the fuel system, causing potential damage to injectors, pumps, lines, and regulators. It also has a short storage and tank life due to its propensity to absorb moisture. |

What You'll Learn
E85 is a biofuel made from biomass sources like corn and sugarcane
Ethanol is a renewable fuel that can be made from various plant materials, known collectively as biomass. It is an alcohol used as a blending agent with gasoline to increase octane and reduce carbon monoxide and other harmful emissions. While ethanol is often associated with methanol, a corrosive wood or petroleum-based alcohol, ethanol itself is not corrosive. However, when mixed with water, it can cause corrosion, which can be minimised by keeping the fuel tank full when the vehicle is stored.
E85 is a popular choice for flexible-fuel vehicles (FFVs), which are designed to run on blends of ethanol and gasoline. These vehicles have ethanol-safe fuel systems, ensuring compatibility and preventing any potential damage to the fuel lines, pumps, and other components.
It is important to note that older vehicles, particularly those manufactured before 1994, may not have ethanol-resistant fuel systems. In such cases, using E85 could potentially harm the fuel lines and other components. Therefore, it is recommended to verify the compatibility of your vehicle with E85 or consider installing an E85 capability kit to ensure safe and optimal performance.
By converting to E85, you can benefit from its excellent cleaning properties, as it helps keep your engine, fuel lines, and injectors free from deposits. Additionally, E85 is a more environmentally friendly option, offering significant reductions in greenhouse gas emissions.

E85 contains up to 85% ethanol and 15% gasoline
E85 is a blend of ethanol and gasoline, with ethanol making up to 85% of the mixture and the rest being gasoline. The exact percentage of ethanol in E85 depends on the geographical location and the time of the year. In summer, producers add more ethanol to the blend, while in winter, the percentage of gasoline is increased to improve cold-weather starting for flex-fuel vehicles.
E85 is also known as flex fuel and can be used in any vehicle designated as a flex-fuel vehicle by the manufacturer. Flex-fuel vehicles have specially adapted components and revised engine software that enable them to run on both ethanol-gasoline blends and regular gasoline. These vehicles can use any mixture of ethanol and gasoline up to E85, which is defined as an alternative fuel.
It is important to note that E85 can be harmful to fuel lines, fuel pumps, and other fuel system components that are not resistant to ethanol. Vehicles manufactured before 1994 did not have to be compatible with ethanol-based fuel and may have fuel systems that are not ethanol-resistant. For such vehicles, it is recommended to use an E85 capability kit, which optimizes the fuel injection process for E85 and includes an ethanol sensor to monitor the ethanol content in the fuel.
While there are myths about E85 damaging engines, fuel lines, and fuel injectors, these are not true for vehicles that are compatible with flex fuel or have the right kit. In fact, E85 is an effective cleaner that can remove deposits from the engine, fuel lines, and fuel injectors, improving the performance of these components.

E85 is a cost-effective fuel option
E85 is an ethanol-gasoline fuel mix, usually with a ratio of 85% ethanol to 15% gasoline. Ethanol is made from plant materials such as corn, sugarcane, and grasses. It is a renewable resource that is domestically produced and better for the environment.
While E85 is typically cheaper per gallon than gasoline, it is important to note that it might be more expensive per mile. Since ethanol contains less energy per volume than gasoline, flex-fuel vehicles will generally get 15-27% fewer miles per gallon when fueled with E85, depending on the car and the driver's driving habits.
To ensure the compatibility of your vehicle with E85, look for markers on the outside of the car with labels such as "E85", "FFV", or "Flex Fuel". A yellow gas cap or a yellow ring around a capless fuel filler are also good indications that the car can use flex fuel.
For older vehicles, especially those manufactured before 1994, it is important to check if the fuel system is resistant to ethanol. E85 can be harmful to fuel lines, fuel pumps, and other fuel system components that are not ethanol-resistant. However, for vehicles produced in 1994 and later, federal law mandates ethanol-safe fuel systems, making engine damage from E85 a non-issue.

E85 is safe to use in vehicles manufactured in 1994 or later
E85 is a biofuel made from biomass sources such as corn crops, grains, starchy wastes, and sugarcane. It contains up to 85% ethanol and the rest is gasoline. In the early 1990s, the US federal government passed a law requiring all new vehicles to be compatible with ethanol-based fuels. This means that vehicles manufactured in 1994 or later are safe to use with E85.
E85 is a cost-effective fuel that has a high octane rating, which can improve engine performance. It is also an excellent cleaner, removing deposits from the engine, fuel lines, and fuel injectors. This is because ethanol, which makes up most of E85, is an effective cleaning agent.
However, it is important to note that E85 has a hydroscopic nature, which means it attracts moisture from the air. This can lead to a buildup of water in the fuel system, causing potential damage to injectors, pumps, lines, and regulators if not properly addressed. Therefore, it is recommended to avoid long storage periods with E85 in the fuel tank and to use pump gasoline every third or fourth tankful to eliminate potential issues.
Additionally, E85 has a low lubricity, which can cause challenges in cold weather as the fuel attracts moisture and can result in water in the gas tank. This can lead to rust formation and even engine choking if not managed properly. It is advised to maintain adequate lubricity in the vehicle and use ethanol-free gasoline if necessary.
In conclusion, while E85 is safe to use in vehicles manufactured in 1994 or later, it is important to be aware of its hydroscopic nature and low lubricity. Proper maintenance and the use of pump gasoline can help prevent potential issues and ensure a smooth driving experience with E85.
