Why is gasoline so harmful to diesel engine components?
Gasoline acts as a solvent and diesel is a lubricant. If gasoline is dispensed into a diesel fuel system, the lack of lubrication will cause the metal to metal contact to produce small sharp fragments of metal that then work their way through the system. It also causes damage to the fuel lines, filter, injectors and rubber seals.
Is the Fuel Angel compatible with all blends of diesel (biodiesel, renewable diesel, off-road diesel)?
Yes. The device is compatible with all diesel fuels.
