What is biodiesel?
Cleaner-burning alternative fuel made from renewable resources.
Can be used as a pure fuel (B100) or blended with petroleum diesel fuel to create a biodiesel blend.
Typical blends of biodiesel fuel include B2, B5, B10 or B20. For example, B20 represents a mix of 20 percent biodiesel and 80 percent petroleum.
Is biodiesel approved for use in the United States?
Yes. It's one of the most tested alternative fuels on the market.
It's registered as a fuel with the Environmental Protection Agency (EPA) and meets clean diesel standards established by the California Air Resources Board (CARB).
Clean Air Act tested and approved.
What are the environmental benefits of biodiesel?
Cleaner-burning fuel that is biodegradable and non-toxic.
Compared to petroleum-based fuels, biodiesel releases less carbon dioxide, unburned hydrocarbons and particulate matter - all major contributors to greenhouse gas emissions.
Provides a positive energy balance. According to the National Biodiesel Board, for every unit of energy needed to produce a gallon of biodiesel, 3.24 units of energy are gained.
Developed from renewable resources, such as soybeans, biodiesel can help reduce our dependence on foreign oil.

What are the performance benefits of biodiesel?
One of the major advantages of biodiesel is that it can be used in existing engines and fuel injection equipment with little impact to operating performance.
Superior engine lubricity resulting in less equipment downtime.
Can biodiesel be used in standard diesel engines?
Diesel engines require a few modifications to run on biodiesel fuel blends.
Without proper alterations, biodiesel can harm fuel system components - primarily hoses, pump seals and filters.
Biodiesel will gel in cold conditions, similar to petroleum diesel fuel. Higher biodiesel blends typically gel faster, although biodiesel blends up to B20 require the same fuel management as petroleum diesel.
Does Exmark support biodiesel in its product lineup?
Yes. Exmark® has approved the use of B20 for all its 2009 (serial # 790,000 or higher) Lazer Z® XS Diesel powered mid-mount zero-turn riders.
Who are the key users of biodiesel?
It's used across many industries. Within the turf industry, key users could include cities, schools, sports fields, golf courses and landscape contractors.
Where do I get biodiesel?
Biodiesel is available throughout the United States.
The National Biodiesel Board (www.biodiesel.org) maintains a list of registered fuel suppliers, petroleum distributors and retail fueling sites. Biodiesel must be produced to strict specifications.
Fuel cost varies regionally due to manufacturing capacity and many other factors.
