A remote petrol pump in the Scottish Highlands is selling diesel at 213p-a-litre - believed to be the UK's most expensive fuel.
It equates to just over £9.67p a gallon - and still people queued to fill up today.
The Cluanie Inn - on the A887, the main Skye to Inverness road - was also advertising unleaded petrol at 208.7p-a-litre on Wednesday.
The price of petrol saw its biggest daily jump in 17 years on Tuesday, with a rise of more than 2p a litre, according to the RAC.
The motoring organisation said the average cost of filling a typical family car with petrol was now £99.40.
It warned the cost could exceed £100 as soon as today (Thursday).
Soaring fuel prices have been driven by the war in Ukraine and sanctions to reduce Europe's dependence on Russian oil.
On Tuesday, the average price of petrol rose to 180.73p per litre, the RAC said.
Meanwhile, the average price of diesel rose by almost 1.5p to another record high of 186.57p per litre, making the cost of filling a 55-litre family car £102.61.
RAC fuel spokesperson Simon Williams said: "These are unprecedented times in terms of the accelerating cost of forecourt fuel.
"Sadly, it seems we are still some way from the peak.
"While the average price of diesel is heading towards £2 a litre, the cost of wholesale petrol unexpectedly dropped around 5p a litre on Tuesday.
If this price is maintained in the coming days it could stem the flow of daily record petrol prices."
The Cluanie Inn's pump price is despite Chancellor Rishi Sunak cutting fuel duty rates by 5p recently as motorists struggle with record fuel prices.
It re-opened earlier this year after a short seasonal shut-down.
But before that motorists took to social media to vent their astonishment when pump prices hit 184.9p-a-litre for diesel and 165p-a-litre for petrol.
"Gold flakes in that fuel," wrote one.
"At least Dick Turpin wore a mask," said another, while a driver added: "At that price they don't need to be open all day! Few cars in that's them made a profit... the fuck is it?! Faberge diesel?"
"I would push ma car to next garage," said a fellow motorist.
Another joked: "Might fill up the lorry there tomorrow."
The Cluanie Inn has said that its fuel prices were based on its remote location, the cost of transporting petrol and diesel to the site, and that it relied on a diesel generator to power the pumps and point of sale machine 24/7.
"We do not make any profit out of the fuel sales," Vanessa Crasto, vice president of parent group Black Sheep Hotels, has maintained.
"It is more a service we provide. There is no other fuel pump for many miles and we keep ours open 24/7 as a service.
"The Cluanie Inn has no (mains) electricity. It relies on the diesel generator."
An Indian businessman bought the several properties, including the inn two years ago.
The Mumbai millionaire took the extraordinary step after paying up to £120 a night for dirty rooms, no hot water and microwave meals served by a carpenter.
Sanjay Narang, then 56, visited Inverness-shire at the end of April in 2018 for a hiking holiday with his sister Rachna.
By the first week that May, he had decided to buy three hotels - Letterfinlay Lodge in Spean Bridge, The Cluanie Inn at Glenmoriston and Craigard Guest House in Invergarry - at a total cost of almost £3 million.
Earlier this year the Cluanie Inn was awarded the Traveller Review Award 2022 by @booking .com - and has had a succession of rave reviews from guests.
