Fuel ALERT – Is it dangerous to fill your petrol tank in hot weather?

Britain has just experienced 34-degree temperatures in areas of the country last weekend as the summer approaches. The heatwave will likely be a delight a lot of Brits across the nation but it’s not good news for everyone. There are things that can cause motorists an issue on the roads in the summer months if they are not careful. These include things such as not wearing sunglasses while driving or using inappropriate footwear such as flip flops.

In Britain, there is also a myth about filling up your car’s fuel tank. The myth states that you should not fill the car up if the weather is hot as it is dangerous and can damage your vehicle.

Every summer messages appear on social media motorists about the dangers of filling their tank claiming that it can explore.

Here is an example of what these posts typically say: “Warning! Due to increase of temperature in the next days, please don’t fill petrol to the max. It will cause explosion in the fuel tank.

“If u want petrol, then fill to half and leave a space for air. This week 5 explosive accidents happened due to filling petrol to maximum.

“Dont leave the msg stop here. Let others and your family who drive know about it so they can avoid this mistake…Please DO SHARE THIS MESSAGE.”

However, how much truth is there to this myth? Can you be in any danger if you fill up your car’s fuel tank in summer?

Drivers should not worry about filling up their car and the rumour has been debunked.

RAC spokesperson Rod Dennis previously said: “There is no truth in this. All fuel systems on passenger vehicles are designed to cope with any expansion of fuel, or vapour coming from the fuel.

“There is no risk of explosion from filling up a fuel tank fully and drivers should have no concerns in doing so.

“There’s a much greater risk of drivers running out of fuel when on long journeys, so we’d actually encourage topping up fully where it’s practical to do so.

“We’d recommend people avoid the temptation to share misinformation like this via social media.”

The AA is also in agreement, adding: “This is an old story that often pops up again and again on social media.

“There is no need for anyone to panic – manufacturers design and build cars to operate in all climates and are tested to weather extremes including hot and cold.”

Drivers should be worried about different elements of their car in the summertime as the heat can cause separate issues.

Brakes that overheat can ‘fade’ which means that they ate less effusive and can lead to failure.

In high temperatures, the risk underinflated tyres causing a blowout increases by 60 per cent.
