Is it true that biodiesel can ruin my engine?
Biodiesel most certainly does NOT ruin your engine. Most engine manufacturer in the world approves the use of biodiesel in their engines, unless of course your engine is not made to run on diesel fuel. Gasoline engines should not be ran on Biodiesel.Actually, if you don't change out your fuel pump, injectors, and fuel lines to accommodate the much thicker biodiesel fuel, it CAN ruin your engine.
