Are there any long-term negative effects of using biodiesel?
There are no negative effects of biodiesel on a car’s engine and components (please read the disclaimer regarding questions about fuel filters). Because of the risk of topsoil erosion that may result from over-farming, biodiesel production needs to be thought of as one important part of the U.S. energy solution, not the only part. Depending on the ability of the U.S. and other countries to manage their long-term renewable energy strategies, biodiesel can serve a valuable function well into the future.
