Hello!

The spark ignition used in a standard gasoline-powered engine would have a very hard time achieving combustion with vegetable/canola/cooking oil. The fuel lines and pumps in a gas engine are not intended to handle this type of fuel, and many of the sensors used to determine fuel ratios in modern cars can't cope well with this variation.

There are so many other factors such as federal regulations, scaling the use of cooking oil across lareg # of cars, side effects of using a non-prescribed oil for cars, etc etc, EVEN if you assume that somehow we can get the "combustion" part to work technically.

Hope this helps.

Thanks,
