Yes, I do the same. Others seem to buy this thing called petrol, that they have to go to the petrol store, to pay for. The get in line, to wait for someone to puts it in their vehicles. Doesn't last very long, so they have to go back like every week to repeat the process, and keep buying more. It's not good for their motors, and seems to degrade every part it comes in contract with, and the exhaust rots out the pipes. So they have replace parts and buy a new car, every 5 or 10 years, before it dies. Strange addictive habit, but they seem to like the way it sounds & smells. Go figure.
