Can Propel biodiesel be used in an older diesel vehicle?
Yes, if you drive a pre-1990 diesel vehicle, we suggest you update your original rubber hoses and gaskets to the synthetic VitonĀ® brand. This is because biodiesel naturally cleans your engine as you drive, drastically increasing the life of your engine. As such, the dirty byproduct can slowly degrade any natural or nylon hose or gasket. For more information visit Driving with Biodiesel.
