Can you mix diesel with b20 diesel?
Yes, you can mix diesel with B20 diesel. B20 is simply diesel fuel blended with 20% biodiesel. Mixing them will result in a blend with a biodiesel percentage somewhere between 0% and 20%, depending on the proportions. Most modern diesel engines are compatible with blends up to B20. However, it's always a good idea to check your vehicle's owner's manual to confirm its compatibility with biodiesel blends.
