Back in the late '50s, I was considering buying an English Ford Anglia from an old man (I'm about his age, now!)
I asked him if the car got good mileage.
His response was............."Why son, this car gets such good mileage, you'll have to stop every 20 miles, or so, and drain some out!"
I didn't buy the car.......too much trouble, doing all that stopping and draining.
