I have heard about the great advantages to using biodiesel in many different gas guzzling machines but I was recently was wondering if these same advantages could be replicated in diesel engines. So I did a study on the effects of biodiesel on diesel engines and I found that not only is it great on just about any engine, it is particularly great for diesel engines as well. What I learned is that not only is gasoline expensive and mostly not produced here in the states, but it is rather harmful for the engine and that biodiesel can actually help your diesel engine run smoother.
