A driver was left shocked when he learnt the proper use for a slot on his car petrol cap.

Justin, who posts on TikTok, revealed the mind-boggling discovery about the fuel cap he once thought was useless.

In the clip, he shows himself removing the fuel cap from his car, as if he was going to fill it up with petrol.

He then points to a 'slot' on the fuel door and hangs the cap on it.

And in a voiceover, he says: "Thirty-eight years on this Earth and I just learnt this."

The original video, posted by @milltj01, has gone viral – with over one million views and 45,000 likes.

After watching the clip, others have had the same revelation and have tried the trick out for themselves.

One man, posting under the username @aketton, responded to the original video, saying: "No, I'm not having that. Oh my days."

He showed his 64,000 followers how his car also had a slot for the fuel cap.

In absolute disbelief, he held his head as he rushed to another car to see if the hack worked on other vehicles.

THINKING CAP

In his second attempt, there wasn't a slot – but instead, the door has a small hook on it to hang the fuel cap off of.

He said: "How did I not know that. I normally let it dangle and knock about like that."

This isn't the first trick that people have learnt from the social media app.

Last week, a user on the popular video platform claimed we've been using the cleaning blocks you hook over your toilet seat wrong.

The Australian man claimed the hook is meant to be pushed up and under the rim of the bowl, to secure it in place without having the hook on show.

The unusual technique also means that the toilet seat can rest snugly on top.

"It slots up inside instead of hanging over," he wrote, along with a face palm emoji.

His video has been viewed millions of times and attracted thousands of comments.

Many thought the trick was "mind blowing" while others cast doubt over whether the item was meant to be used in the position claimed.

"I really don't think that's the way it's supposed to go," one person said.

"No thanks, I'll keep doing the old way; it's a lot cleaner," another stated.

While one asked: "But how do you get it out without touching it?"
