Petrol and diesel vehicle owners are being advised to ensure their fuel tanks are as "full as possible" this Wednesday as warm weather arrives. Temperatures of 24C are forecast in Wales on Wednesday, and warm conditions could arrive again this weekend.
Fuel experts at 1dot warn that approximately 1-2% of petrol and diesel could evaporate under extreme heat. Specialists from All on the Wrist Auto and Diesel Repair added: "Excessive heat can lead to increased evaporation of diesel fuel, potentially causing vapor lock and reduced engine efficiency."
‌
They further cautioned: "Additionally, engine oil may become less viscous in hot conditions, potentially compromising its protective properties."

Hence, motorists are being encouraged to keep their fuel tanks as full as possible. For our free daily briefing on the biggest issues facing the nation, sign up to the Wales Matters newsletter here
However, amidst the rising temperatures across the UK, online reports have been circulating, falsely suggesting that filling up during a heatwave could result in petrol tanks exploding.
These erroneous posts, which have been shared on Facebook and Whatsapp for years, wrongly assert that five cars exploded in the past week due to owners filling their tanks to the brim, reports Birmingham Live.

The RAC has categorically debunked these claims as nothing more than a social media hoax.
In response to the rumours, RAC spokesperson Rod Dennis stated: "There is no truth in this."
He reassured drivers by saying: "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.
"We'd recommend people avoid the temptation to share misinformation like this via social media."
Mr Dennis advised motorists to fill their tanks to the brim when possible, particularly before embarking on extended trips.

He also warned that while hot weather can present additional challenges, it's crucial to take measures to prepare for the rising summer temperatures.

Campervan stuck in sand at popular beach swept out to sea

Dramatic photos captured the motorhome being engulfed by the advancing sea as waves can be seen crashing off the vehicle just off the Welsh coast. This is the moment a stricken campervan stuck on a UK beach was swept out to sea despite a daring rescue effort by jet skiers. Dramatic photos captured the motorhome being engulfed by the advancing sea as waves can be seen crashing off the vehicle just off the Welsh coast. ‌ As the Mirror reports, the vehicle became overwhelmed by the tide near Traeth y Grieggdu - Black Rock Sands - near Porthmadog, Wales last Friday. It's wheels became lodged in the sand before being lost, with eyewitnesses reporting that there was an attempt to save the campervan. ‌ A rescue bid was led by jet skiers who were at a fundraising event by Colwyn PWC Riders. It is understood the same vehicle become stuck once already that day and was rescued with the assistance from the vehicles of the jet ski riders. However by the time of the second rescue the tide had been too fast. People reportedly rallied around to help the rooted vehicle. A witness described around six jet skiers trying to help the owners. Attempts were made to try and two the van to safety with a pick-up truck along with a 4x4 Land Rover Defender. One of those helping said: "We tried to move the camper a second time but it wouldn't move, the wheels didn't spin, they were stuck. We then tried a third time to retrieve the camper - attempting to drag it out with two vehicles but this time it was totally stuck. "We were in danger of digging into the sand ourselves. Someone then called for the tractor, and the rest is history." ‌ Phil Butler, an admin on Abersoch Appreciation Page, said he wanted to set the record straight. He said: "A few people who weren't even there, are saying, why did no one attempt to help, but some people certainly did." He added: "Even using two towing vehicles the camper would not move, so eventually it had to be left exactly where it was stuck. The incoming tide won the battle."

They too were left helpless as the tide came in but remarkably their vehicle was saved. Eyewitnesses say the beach was packed with people in April 2022 when the people inside suddenly realised the sea was creeping closer to the van. When they tried to move, the wheels spun helplessly leaving them to ask for help from those nearby. ‌ When a 4x4 could not help, a tractor was called for to haul it from the waves lapping at its tyres. People at the scene said the people in the vehicle were shocked at what had happened. One said: "They realised the tide was coming in and tried to move the camper but it was stuck fast. Attempts were made to pull it out before the water got to it but that didn't work. I don't know how it never floated away before the tractor arrived and succeeded in pulling it free."

Top MOT fault for UK drivers and how likely it will cause you to breakdown

The RAC has revealed the most common fault flagged up on MOT tests in the UK, which could lead to an unfortunate breakdown or costly repair - and it's nothing to do with the brakes Brits are being urged to check their cars for a common fault that could leave you broken down and out of pocket. It's a yearly event that many motorists would rather skip — the dreaded MOT test. For some drivers the process is straightforward and trouble-free, but for others it can quickly become a costly calamity, revealing a long list of essential repairs. ‌ There is also a sizeable group that falls somewhere in between: their cars pass the MOT with advisories, with mechanics flagging issues that should be addressed sooner rather than later - but still allow Brits to drive off without having to deal with the problems straight away. But, ignoring these advisories can have serious consequences, as revealed by a recent RAC survey of almost 1,500 motorists. ‌ According to the findings, one in six drivers who ignored an MOT advisory in the past year ended up experiencing a vehicle breakdown or crash as a direct result of the unresolved issue flagged by the garage. The RAC described the phenomena as 'troubling advisory apathy among drivers'. READ MORE: Major MOT test changes that could impact millions of UK drivers What is an MOT? The annual MOT, which is required for cars, vans and motorcycles from their third year of registration, is a roadworthiness check covering a range of consumable parts — including lights, seatbelts, tyres and brakes — to ensure they meet legal standards. Vehicles found to have 'dangerous' or 'major' defects automatically fail the test. However, 'minor' problems are recorded as advisories because they are not severe enough to cause an immediate failure. Still, they are highlighted as issues that should be resolved in the near future to keep the car roadworthy. The RAC survey found that more than two in five drivers reported receiving one or more advisories at their last MOT. Despite this, more than half (54 per cent) admitted they did not act on the warning and neglected to get the problem fixed. RAC mobile servicing and repairs team leader, Nick Mullender, emphasised the importance of MOT advisories, saying they 'demand attention' because they indicate a vehicle 'isn't in the best of health'. He cautioned: "Unfortunately, our research suggests there's a lot of troubling advisory apathy among drivers. ‌ "Advisories indicate the potential for the vehicle to become unroadworthy in a matter of months or even weeks, depending on the nature of the issue and how often the vehicle is driven. It's crucial that drivers keep a close eye on any flagged items. An MOT is the most basic of roadworthiness checks, and no replacement for a proper service by a qualified mechanic." The RAC's survey found the most common advisories on MOTs arranged by drivers between May 2024 and May 2025 included issues with the tyres, brakes and suspension. Other factors included problems with the car's lights or exhaust system. ‌ Tyres (e.g. tread, wear, quality): 42% Brakes (e.g. pads or discs): 34% Suspension: 22% Lights: 16% Corrosion: 14% Something else: 11% Exhaust system: 9% Steering: 8% Visibility (e.g. out of windscreen): 8% Other electrical system: 4% Bodywork damage: 2% According to Driver and Vehicle Standards Agency (DVSA) records for 2023-24, 34.7 million vehicles underwent MOT testing. Of these, 7.9 million initially failed — accounting for 28.4 per cent of cases. Notably, 2.7 million of these failures were due to dangerous defects, suggesting that 7.9 per cent of vehicles on the road had serious faults posing a real risk to owners, passengers and other road users. The consequences of this inaction can be severe. 17 per cent of those who ignored advisories said their vehicles subsequently broke down or were involved in a crash directly linked to the advisory defect highlighted during the MOT. But the good news is that tyre tread issues are among the easiest MOT faults to avoid. Simply check them regularly using a tread depth gauge or the '20p test' — insert a 20p coin into the tread and if the rim is visible, your tread is too low. Drivers should also ensure their tyres are inflated to the correct pressure and check for signs of uneven wear. So while the word 'advisory' may make the issues seem less than pressing, ignore them at your own peril. You could wind up with a hefty repair bill — or worse, involved in an accident.

Everyday summer item could cause £200 damage to your car

Everyday summer item could cause £200 damage to your car The oily substance is notorious for leaving nasty stains on vehicle upholstery It's the nemesis of car seats (Image: Getty Images/Car Culture ) Motorists who make this hot weather mistake could face a £200 repair bill, it was been warned. As Wales is currently experiencing a heatwave, don't get caught out by this costly error. Drivers have been warned to avoid contaminating car seats with sunscreen or sun cream - as the oily substance is notorious for leaving nasty stains on vehicle upholstery that can be a nightmare to remove. Motorists might ultimately have to pay for their vehicle's cabin to be professionally cleaned, an expense which can cost £200. Managing director at Select Car Leasing, Graham Conway, said the water-resistant nature of sun cream is what makes it "the nemesis of car seats". He explained: 'When the temperature rises, sun cream is a must, particularly if you're out and about in the car, as harmful UV rays can penetrate both windscreens and side windows. 'But sun cream and car seats are also a recipe for stains that can be near-impossible to remove. Article continues below 'Sun cream is, by its very nature, water resistant so that it doesn't disappear from your skin at the first sign of sweat or moisture. 'But because it's resistant to water, sun cream also repels common interior car cleaning products. If it's left too long on vehicle upholstery, you might struggle to get rid of the stain at all.' According to experts at the British Skin Foundation, there are two main types of sunscreen in the UK; chemical sunscreens and mineral sunscreens. Mineral sunscreens often appear much whiter on the skin and contain the chemicals titanium dioxide or zinc oxide. And it's these oxides that can leave a stubborn white residue on car seats, particularly leather or artificial leather. Mr Conway added: 'Prevention here is better than cure - if you accidentally slap sun cream on your car seats, try and remove it with a cleaning wipe as soon as you can." For more stubborn sun cream car stains, the advice differs between experts, with some recommending using a mild degreaser or applying white wine vinegar to the stain. Other advice is simply to use baby wipes - with a pack of wipes costing just £1. American YouTuber and dermatologist Dr. Scott Walter's advice has been viewed more than 35,000 times. In the video, he says: 'I love sunscreen but one thing I hate about it, it gets all over my car. I finally found something to clean it without doing any damage - baby wipes. Baby wipes do a fantastic job of removing it without hurting the leather or other parts of the car.' Mr Conway said that when the sun is out people should use at least SPF 15 sunscreen with UVA protection when in their car. But he added: 'You should avoid leaving a bottle of sunscreen in your car's glovebox. 'While it might be convenient when it comes to applying protection before you set off on a journey, some of the active ingredients in sunscreen actually break down when exposed to high heat from sitting in your car, rendering it less effective.'
