The number of ‘red line runner’ drivers who run their fuel tank to almost empty before filling up is on the rise, despite the cost and safety risks.

31% of drivers are more likely to run their fuel tank as low as possible before refuelling due to the current cost-of-living crisis

New research from Green Flag finds 31% of drivers are more likely to do this due to the current cost-of-living crisis. Young drivers are the most likely to risk running out of fuel, with half (51%) of ‘red line runners’ aged under 35.

But running down fuel gauges can be a risky business. Nearly three in 10 drivers (28%) admit their vehicle has run out of fuel before, rising to over half (55%) of 18-34-year-olds.

Driving a car regularly with low levels of petrol or diesel can also cause damage to a vehicle, as debris in the fuel tank can clog the fuel pump or filter.  There is also the risk of suddenly having no power, potentially on a busy road, or becoming stranded in a remote location.

Katie Lomas, head of Green Flag Breakdown, commented: “While drivers are under more financial pressure than ever, not putting fuel in a car could be a false economy as constantly running a tank low can cause mechanical problems, not to mention the inconvenience of breaking down. Prevention is always better than cure and we know that many breakdowns are avoidable if proper care is taken before and during a trip, so keep the tank with enough fuel to complete your journey safely.”

The Green Flag data also shows nearly three-quarters (70%) of motorists have changed their driving habits due to the cost-of-living crisis. Over a third (37%) of drivers have cut down on driving for leisure purposes, while around one in five have either changed their driving style (20%) or combined journeys (19%) to conserve petrol. Others have actively reduced their use of air conditioning and heating to cut back on fuel (15%) consumption. The average motorist also now drives 23 fewer miles each month compared to January.
