E85 is a type of fuel that contains up to 85% ethanol and 15% gasoline. It is a cheaper and more eco-friendly alternative to gasoline, but it is not suitable for every vehicle. E85 should only be used in flex-fuel vehicles (FFVs) that have a fuel system and engine designed to use it. FFVs are capable of running on both ethanol-gasoline blends and regular gasoline. Using E85 in a non-FFV vehicle can ruin the engine and void the manufacturer's warranty. Vehicle owners can check their owner's manual, the fuel door, or fuel cap to see if their vehicle is E85 compatible.

What You'll Learn
E85 is a blend of ethanol and gasoline
E85 is a high-performance fuel that offers several advantages over regular gasoline. Firstly, it is more affordable than regular gasoline, making it a cost-effective option for drivers. Secondly, it has a higher octane rating, typically around 100-105, which translates to better engine performance, especially for performance vehicles. Additionally, E85 has a higher resistance to engine knocking due to its octane rating and cooling properties.
Another benefit of E85 is its positive environmental impact. As a blend with a high ethanol content, E85 burns cleaner than regular gasoline, resulting in fewer carbon emissions. This makes it a more environmentally friendly choice, contributing to cleaner air. Furthermore, E85 can enhance engine performance, generating more torque and horsepower than gasoline.
However, it is important to note that E85 is not suitable for all vehicles. It is specifically designed for flex-fuel vehicles (FFVs), which have a fuel delivery system and engine engineered to use ethanol-gasoline blends. FFVs can detect the ethanol content and adjust their engine operation accordingly. While E85 can be used safely in FFVs, it is not recommended for non-flex-fuel vehicles. Using E85 in a non-compatible vehicle can cause issues with engine performance and may even damage the engine, leading to costly repairs.

Flex-fuel vehicles can use E85
Flex-fuel vehicles (FFVs) are specially designed to run on any ethanol-gasoline blend, including E85. E85 is a special type of fuel that consists of up to 85% ethanol and 15% gasoline. Ethanol is a renewable resource made from crops like corn, sugarcane, and grasses.
FFVs have sensors and a fuel system that can detect the ethanol content and adjust the engine operation accordingly. They are also distinguished by a yellow fuel cap and a badge or emblem on the rear of the car, indicating E85 use is allowed. The FFV system is available in several car models, including Chrysler, Ford, Toyota, Volkswagen, Hyundai, Mazda, Jaguar Land Rover, and Nissan. All Mercedes-Benz models are also E85 compatible.
To determine if your car is an FFV, you can check your owner's manual, the fuel door, or the fuel cap for any indicators of E85 compatibility. Additionally, you can use your Vehicle Identification Number (VIN) to look up your car's specifications online or with the manufacturer.
It is important to note that E85 should only be used in FFVs. Using E85 in a vehicle that is not built or converted for flex-fuel can damage the engine and void the manufacturer's warranty.

How to check if your car is a flex-fuel vehicle
E85 is a special type of gas that consists of up to 85% ethanol and 15% gasoline. It is not suitable for every vehicle. Flex-fuel vehicles (FFVs) are specially engineered to run on any ethanol-gasoline blend, including E85. These vehicles generally have sensors and fuel systems that can detect the ethanol content and adjust the engine operation accordingly.
Check Your Owner's Manual
The easiest way to determine if your car can use E85 is by consulting your vehicle's owner's manual and seeing what fuel is recommended. Buried deep inside the owner's manual is also a notice about which fuels are approved to run in your vehicle.
Look for a Flex Fuel Badge or Yellow Gas Cap
Many flex-fuel vehicles have a badge or emblem on the rear of the car, or at least a yellow gas cap that often has a label “E85”. 2008 and newer vehicles will have a yellow fuel cap and a badge.
VIN Lookup
If you are still unsure, you can use your Vehicle Identification Number (VIN) to search for your car's specifications online or with your manufacturer. FFV models are identified by using the 8th character in the vehicle identification number and a decal under the fuel door indicating E85 use is allowed.
Check the Vehicle Emissions Control Information Label
To determine if the vehicle is E85 compatible, Chrysler designates flexible fuel vehicles with the last letter of the 12-character Test Group Name posted on the Vehicle Emissions Control Information label, found under the hood. The Test Group Name is located on the right of the label, just below the engine size. Look for “Group: XXXXXXX.XXXX” then check to see if the last letter falls within the letter groups at the right.
Check the Make and Model of Your Car
The FFV system is available in each of the Ford, Chrysler, Toyota, Volkswagen, Huyndi, Mazda, Jaguar Land Rover, and Nissan models. All Mercedes-Benz models are also E85 compatible.

E85 is more affordable and eco-friendly
E85 is a special type of gas consisting of up to 85% ethanol and 15% gasoline. It is a more affordable fuel option with a higher octane rating than regular gasoline, generally around 100-105. This means it offers better engine performance, especially for performance vehicles.
E85 is also more environmentally friendly than regular gasoline. It is a cleaner-burning fuel with fewer carbon emissions, reducing your vehicle's carbon footprint by 35% if used as the primary fuel source. The ethanol in E85 is produced in the USA, primarily from corn, and does not contain harmful hydrocarbons or additives found in gasoline. As a result, E85 burns more cleanly, reducing the release of harmful gases that cause air and water pollution, global warming, and smog.
While some argue that E85 reduces miles per gallon (MPG), and therefore increases emissions, this is not always the case. Many blends of flex fuel yield the same MPG as gasoline, and even when E85 does reduce MPG, it still produces fewer emissions overall. The environmental impact of E85 is expected to improve over time, with the USDA predicting that corn ethanol's carbon benefits will rise to at least 50% by 2022.
E85 is a great option for those looking to reduce their carbon footprint and take advantage of a high-octane, eco-friendly fuel. However, it is important to note that E85 is only compatible with flex-fuel vehicles (FFVs) that are either factory-built or retrofitted with a quality flex-fuel system.

Using E85 in a non-flex-fuel vehicle
E85 is a blend of ethanol and gasoline, with up to 85% ethanol and 15% gasoline. It is a high-performance fuel with a higher octane rating than regular gasoline, resulting in better engine performance and reduced emissions. While E85 is a tempting option due to its affordability and environmental benefits, it is not suitable for every vehicle.
If you use E85 in a non-flex-fuel vehicle, you may experience issues such as lean mixture codes, misfires, and confusion in the vehicle's computer system. The computer may try to adapt to the E85 fuel, which can mess with the fuel trim and cause the vehicle to act erratically. In some cases, the vehicle may struggle to accelerate and then suddenly jerk forward when shifting gears.
To address these issues, you may need to reset the fuel tables or perform an injector flow test. Some people suggest diluting the E85 with regular gasoline to reduce the ethanol content and improve drivability. However, this will result in decreased power until you burn through the diluted fuel and refill with normal gasoline.
It is important to note that modern gasoline engines are not designed to tolerate E85 fuel. Therefore, it is recommended to use the manufacturer-recommended fuel for your vehicle, unless you have an older vehicle with a carbureted engine.
If you are considering using E85 in a non-flex-fuel vehicle, it is essential to consult a mechanic or a specialist in flex-fuel conversion kits to ensure the compatibility and safety of your vehicle.
