Guide-ConsumersBiodiesel users have more options than ever when it comes to buying biodiesel.  Many petroleum retailers now make biodiesel available at the filling station. In fact, some cities like Las Vegas, Austin and Greenville, SC have more than a dozen biodiesel pumps. If you have a diesel vehicle and a public pump nearby, using biodiesel is a breeze. There are just a few things you should know first.

Biodiesel blends of 20 percent and below will work in any diesel engine without the need for modifications. These blends will operate in diesel engines just like petroleum diesel. If the blend has been properly treated by the petroleum company, it will work year-round, even in cold climates. B20 also provides similar horsepower, torque, and mileage as diesel.

There are a few precautions to take when making the switch to B20:

  • Make sure you buy B20 from a reputable source.
  • Buy fuel that is already blended. This will help ensure that the biodiesel has been properly handled and treated for climatic needs.
  • Never buy from someone making fuel in their garage or backyard.
  • Biodiesel is a cleaning agent, which means petroleum deposits may end up in the fuel filter until the system is clean.  Stick to your regular maintenance schedule, unless your vehicle feels sluggish when accelerating.  This is a symptom of a plugged filter and should be checked immediately.
