What's the dumbest thing you've seen someone do to their vehicle?

My old mechanic had a guy come in with a Ford probe.

He claimed it was low on oil.

They take the dipstick out and the whole stick has oil on it.

He checks again with the same result.

The guy took the oil cap off and looked down into the hole and said,

See, it is low.

He had put three to four cases of oil into the motor

trying to fill the entire block up. The previous mechanic didn't know how to patch an exhaust

leak and had tried to weld a rock star can around the leak. The leak caused the second oxygen

bank to fail, which is why they tried to patch it with the can. Not a week later, the bank read a failure again.

You don't weld it on, you use some sealant and a couple of Jubilee clips.

How the heck do you even weld an aluminium can?

Was he using TiG?

This definitely won't be the worst one in this thread.

I used to know a 30-year-old who would put the car air freshener duct taped outside the exhaust,

kind of just dangling in front of the opening.

His logic was that it would make the exhaust smell better for pedestrians.

That is artly sweet, which was also the fragrance he was going for.

Had a customer once who had their oil light come on and couldn't figure out how to top up the oil.

He thought it might have worked like his boat motor, so he poured a jug of oil into his fuel tank.

What would that do to a car? Fiery dramatic explosion, or just engine damage?
