Drivers are only just realising their car shows them which side their petrol tank is on

After pushing your car to the limit to avoid a visit to the petrol station, the time to fill up has come. You pull into the garage, but wait - which side is the petrol tank on again?

If you've been driving the same car for a while, you might have just about got it into your brain. But if the car is relatively new, or if you just don't pay that much attention, then chances are this is a question you've asked yourself multiple times.

Well, ask no more, because there's actually a very simple way to find out:

I know what you're thinking: "NOW you tell me?!"

For decades, people have been forced to crane their necks out of their car windows, try desperately to see the little raised bump of the tank cover through the wing mirror, or even just take a gamble at the petrol pumps to fill up more quickly, and it turns out we didn't need to do any of that.

The trick to knowing where your petrol tank is without having to get out of the car is really something they should include in driving theory tests - after all, it could save a lot of awkward manoeuvring and mouthed apologies as you attempt to navigate your car to the right side of the garage after an unsuccessful guess.

But instead, drivers have been forced to rely on TikTok to learn the information, with user @tinukeawe changing lives when she revealed there's literally an arrow in the car which points to the side your tank is on.

The TikToker caught her own shocked reaction at this revelation before turning the camera to show the arrow working its magic, with a voiceover explaining: "Guys, I was today years old when I found out that this arrow when you've run out of petrol on your car shows you which side your petrol door is on."

"Please tell me I'm not the only one?" she added.

It quickly became clear that @tinukeawe was definitely not the only one, as viewers praised her for bringing this invaluable information to their attention.

"Omg you're kidding! I had no idea!!" one baffled driver wrote, as another commented: "Oh wow! I didn’t know that."

The arrow can be found right next to the petrol light that comes on when you're running low, meaning that next time you arrive into the garage you don't need to turn yourself into a contortionist to figure out which pump to pull up at.

Life changing.
