FAQ:

Q: How do you test diesel fuel?

A: Open the fuel door. If you have a release lever or button inside your car, release the door to check. Look for a label on the fuel door or by the fuel filler neck. You should find a label that says “Diesel Fuel Only” or “Unleaded Gasoline Only,” or similar wording.

Q: Can I use biodiesel instead of diesel?

A: Any vehicle that operates on diesel fuel can use biodiesel. Biodiesel fuel has chemical characteristics similar to petroleum-based diesel, so it can be used as a direct substitute for diesel fuel. Biodiesel fuel can also be blended with petroleum diesel in any percentage without reducing vehicle fuel economy.

Q: Does diesel fuel go bad?

A: However, just like gasoline, diesel fuel will go bad. With the right diesel storage methods though, you can make your diesel fuel last much longer. Depending on whom you ask, you’ll get a different answer as to how long diesel fuel can last. This is because the lifespan of diesel fuel largely depends on the conditions.

Q: Is synthetic diesel the same as biodiesel?

A: What we’re talking about is synthetic diesel fuel, which is different from biodiesel fuel . Synthetic diesel is made by reconfiguring another hydrocarbon fuel, natural gas, into liquid diesel fuel. Biodiesel, by comparison, is chemically produced from any fat, such as vegetable oil, soybean oil, or even recycled restaurant greases (see “The Biodiesel Alternative” elsewhere on this site).
