A motoring expert has taken to to warn drivers to never make a common mistake when that .
Brian Reider runs the YouTube channel , creating videos in which he tests a wide range of new and and shares tips to help viewers avoid expensive repair bills.
In , Brian urges motorists to stop adding to their vehicle’s tank if the pump’s trigger clicks off.
He advised: “If you fill up your car this way, you’re an idiot. Don’t ever do this. If you’re filling your car and you hear a click, stop right there. Don’t go ‘oh, I’m going to add a little bit more gas [petrol]’ and pull [the trigger] again.
“What you’re doing is putting gas into the fuel filler neck, and that’s no good. Do not do that, and here’s why. Your fuel cap is vented, this is a little vent hole, and down here is a little drain hole. If you overfill, you’re messing up the ventilation of your fuel tank.”

When filling up a car with petrol or diesel, drivers will almost always find that the petrol pump will click when the tank is at its highest recommended level.
At this point, drivers should not be tempted to add slightly more, which will sit in the vehicle’s filler neck, because it could result in the fuel warming up and expanding – resulting in excess petrol or diesel being pushed into the charcoal canister feed line.
If this occurs, a wide range of issues may start to develop, making it harder for drivers to start the engine, more emissions being produced, and the ‘check engine’ light appearing on the dashboard.

Later in the video, Brian highlighted that the issues caused by the bad habit certainly outweigh the benefits that drivers may think they are getting from the additional fuel.
He added: “Plus, if you have an older SUV or truck like this, what is a few soda cans’ worth of fuel really getting you? You’ll get a whole heck worth of trouble for around half a mile down the road of extra range.”
Instead, the YouTuber recommended that drivers should only fill up their tank with however much fuel is needed and top up regularly.
However, whilst drivers could create serious problems by overfilling their tank, many motoring experts have suggested that similar issues could occur if drivers do not put enough fuel in.
Drivers who run their car on fumes, only putting in a few litres each time they visit a petrol station, run the risk of damaging the fuel pump, which is typically cooled down due to being surrounded by liquid.
If it fails due to overheating, the engine will begin to quickly lose power or stall before failing completely as not enough fuel is reaching the powertrain.
