This time, we check out a situation in which someone really screwed up big time and it’s as obvious as a huge waving red flag smacking you in the face.
When this mechanic went to pull out the oil plug for a car that rolled into his shop, instead of a dark brown liquid, a light green and clear liquid would roll out of the pan.
You guessed it, instead of oil, someone put coolant in their oil fill. You might as well go ahead and shove most of the engine in the trash right now. That has to hurt!
