Fuel Fixer data shows wrong fuel incidents are a daily UK problem

Fuel Fixer has analyzed 57,047 fuel drain enquiries from 2024 and 2025, offering one of the clearest snapshots yet of misfuelling on UK roads. The findings show diesel cars account for most callouts, many drivers move their vehicles before calling for help, and repair costs can climb quickly if the engine is started. Why it matters: - Fuel Fixer’s dataset points to a persistent UK road-safety and cost problem, with misfuelling still generating daily callouts across the country. - The analysis also shows how quickly a simple mistake can turn into a far more expensive repair. - The company says the findings represent the most detailed publicly available picture of misfuelling in the UK. What happened: - Fuel Fixer released a statistical analysis based on 57,047 fuel drain enquiries handled across 2024 and 2025. - The company has operated since 2009 and uses a network of 35+ mobile units covering every UK region. - Fuel Fixer completes about 17,500 fuel drain jobs per year and reports more than 8,000 verified reviews across Trustpilot and Reviews.io. - The dataset covers wrong fuel incidents, contaminated fuel and AdBlue contamination. The details: - 86.7% of cases where a reason was recorded were wrong fuel incidents. - AdBlue contamination accounted for 9.1% of recorded cases. - Three in four wrong fuel callouts in the dataset involved a diesel vehicle. - Petrol put into a diesel car accounted for 75% to 78% of incidents. - Diesel into petrol remained a smaller share, but was higher than the 5% figure often cited in older industry estimates. - Friday was the busiest day for callouts, with 29% more cases than Sunday. - May and August were the busiest months, each running about 12% above the January baseline. - The Nissan Qashqai appeared most often, with 1,459 cases across the two years. - The VW Golf followed with 1,114 cases, then the Vauxhall Astra with 859 and the Mercedes-Benz A-Class with 744. - Volkswagen was the most affected manufacturer, accounting for 12.4% of all wrong fuel cases. - Fuel Fixer notes that the vehicle rankings reflect the makeup of the UK fleet, hire and commercial market rather than any inherent susceptibility. - The median amount of wrong fuel added was 20 litres. - More than half of all cases involved 20 litres or less, suggesting many drivers notice the mistake mid-fill. - 68.4% of callers had already moved their vehicle before calling. - The median distance driven after misfuelling was 1.5 miles. - 93% of drivers had covered 10 miles or fewer before getting help. - A standard wrong fuel drain costs £150 to £299. - Delayed action can lead to fuel pump replacement costs of £1,000 to £3,000. - Injector and pump damage can raise costs to £3,000 to £8,000. - In the worst cases, repairs can reach £5,000 to £15,000 or more. - Fuel Fixer reports a median arrival time of 49.7 minutes in 2025. - Most customers were back on the road within 75 to 90 minutes of calling. Between the lines: - The data suggests most misfuelling events happen fast, are noticed quickly, and can still escalate if drivers keep going. - The pattern also shows that weekends and peak travel months are not the only pressure points; weekday use and routine driving create plenty of incidents too. - The vehicle rankings likely say more about which models are common on UK roads than about any special risk tied to those cars. What’s next: - Fuel Fixer is positioned to keep using its mobile network for rapid response as wrong fuel incidents continue. - The company’s response times and repair workflow suggest speed remains the main way to limit damage and cost. - The new dataset may become a reference point for future comparisons on misfuelling trends in the UK. The bottom line: - Wrong fuel mistakes remain common, costly and preventable, and Fuel Fixer’s 2024-2025 data shows the bill gets much bigger when drivers try to keep going.
