Assuming we buy that Kable can run the truck on Vodka with no modifications, the bottle he drank from wasn't particularly big, and the truck wouldn't have run as long as it did on the paltry amount he was able to get into the tank.

Fuel tanks typically need a minimum amount of fuel just to ensure the fuel pump has something to run on, and that bottle isn't going to achieve that, no matter what fictional future technology you can dream up in lieu of whats onscreen.
