Can you run a new car on bio diesel?

It depends on the car. Some new cars can run on biodiesel, while others cannot. It is important to check the owner's manual of the car to see if it is compatible with biodiesel.

Generally speaking, diesel cars built after 2007 are compatible with biodiesel, while older models may not be. Additionally, some manufacturers may have specific requirements for biodiesel use, such as the use of a certain blend or the need for a fuel additive.

If you are unsure whether your car is compatible with biodiesel, it is always best to consult with a qualified mechanic.
