So this guy bought a 1930 Ford Model A to fix up and it wouldn’t start no matter what he tried.
Finally, he decided to drop the oil pan to see what was wrong.
He was surprised at what he found, oil sludge so thick you could cut through it with a knife.
It seems that oil had not been changed in the 50 years that it sat.
Goes to show you how important it is to change your oil, even if the car is just sitting.
