Lol I'm kidding....sort of
One on my deputies took his truck over to the sheriff's office for a oil change tire rotation and fluid fill. And they put about 3/4 gal of oil in the radiator. Someone used a antifreeze jug for oil and the inmate just picked it up and started pouring without looking.
Truck only made it about 6 miles before overheating. They are trying to clean up their mess now
I don't know how you could not see that but I guess
Our Sheriff has our vehicles serviced a local garage with licensed techs doing the work.
The inmates shovel snow, wash police vehicles and keep our little league ball fields nice in spring. But mechanical work is left to pro's.
