Busting Biodiesel Myths

SOME OF WHAT YOU'VE HEARD ABOUT BIODIESEL IS FALSE.

HERE ARE THE FACTS:

 

FUEL FILTERS

MYTH:

Biodiesel clogs diesel engine fuel filters.

FACT:

Biodiesel is a cleaner fuel than petroleum diesel and has inherent cleaning properties.

When you first start to use biodiesel, those cleaning properties naturally remove deposits left by petroleum diesel. That means initially you may need to change filters more frequently. Once deposits have been removed, filter changes should occur at the same rate as petroleum diesel.

 

YEAR-ROUND FUEL

MYTH:

Biodiesel use is limited to summer months only.

FACT:

Biodiesel is a year-round fuel.

Fleets have driven millions of miles in cold weather on biodiesel blends up to B20. It’s important to know the fuel’s Cloud Point, but proper storage, handling and additive use help fleets run confidently on biodiesel blends in the winter.

 

HIGH PERFORMANCE DIESEL

MYTH:

Biodiesel performs poorly in diesel engines.

FACT:

Biodiesel has superior lubricity and higher Cetane than petroleum diesel.

Fleets are also reporting fewer issues with diesel particulate filters on Tier 4 engines thanks to biodiesel’s cleaner burn. Blends up to B20 provide similar horsepower, torque and fuel mileage in diesel engines.

 

RENEWABLE DIESEL

MYTH:

Fleets should switch to renewable diesel because it’s a better overall fuel than biodiesel.

FACT:

Renewable diesel is a great fuel — but not clearly “better” than biodiesel — and is currently in very short supply.

Most of the nation’s renewable diesel supply goes to the West Coast. Any expansion of renewable diesel production capacity likely won’t be online until years from now. In addition to being widely available, biodiesel reduces overall greenhouse gas emissions more and costs less than renewable diesel.

 

FEEDSTOCKS

MYTH:

Biodiesel produced from animal fats is inferior to vegetable oil-based biodiesel.

FACT:

A skilled producer can make high-quality biodiesel out of a variety of feedstocks.

A feedstock-flexible approach lets producers capture the best characteristics of different feedstocks, meaning there is no one “best” feedstock.

 

FOOD SUPPLY IMPACT

MYTH:

Biodiesel production negatively impacts the food supply and causes rising prices.

FACT:

Biodiesel is made from excess or waste fats and oils from animals and plants, so it has no impact on the food supply.

Biodiesel supports food production by creating additional revenue streams for excess or waste fats. It is a food-then-fuel approach.

 

EASY TO USE

MYTH:

Using biodiesel requires modifications to engines and fleet fueling infrastructure.

FACT:

Biodiesel blends up to B20 are drop-in fuels, meaning they require no modifications to fueling infrastructure or engines.

 

OEM WARRANTIES

MYTH:

Biodiesel will void OEM warranties.

FACT:

Use of biodiesel manufactured to the ASTM D6751 specification (which is all commercially produced biodiesel) is supported by OEMs.

100% of OEMs support using B5 biodiesel, and nearly 90% of medium- and heavy-duty truck OEMs support B20 blends.
