Why does octane matter?
Octane is a rating that is based on the pressure at which a fuel will spontaneously combust in a testing engine. Higher octane is required for high performing engines.
What is a Flex Fuel and who can use it?
A Flex Fuel is a high ethanol content fuel that is commonly offered with 85% ethanol and 15% gasoline. This fuel should only be used in vehicles when the owner's manual recommends the product.
Can I use Unleaded 88?
Unleaded 88 is also known as E-15. It is a blend of 85% gasoline and 15% ethanol. The blend is the most tested fuel ever approved by the EPA and is for use in vehicles 2001 and newer. It is higher octane and helps your engine burn cleaner and cooler.
What kind of gas should I use in my car?
Please review your owner's manual for the recommended fuel for your engine.
What is ethanol?
Ethanol is made from a renewable source, commonly corn, that is a cleaner burning fuel and is better for the environment. Ethanol is one of the least expensive sources of octane. This results in lower fuel prices for our customers.
What is biodiesel?
Biodiesel is a renewable, clean-burning alternative to regular diesel. With few to no modifications, biodiesel can be safely used in most diesel engines. Refer to your owner's manual to see if your engine can run on biodiesel.
