A survey of 800 drivers finds that 99% know where to find the dipstick in their car and nearly 94% know how to change a tyre when faced with a puncture.
Even if stuck in a really sticky situation, more than 95% of drivers surveyed know how to jump start a car.
Only 12% of drivers admitting to filling up their car with the wrong fuel.
The survey was conducted by road safety and breakdown organisation GEM Motoring Assist.
David Williams MBE, CEO of GEM Motoring Assist, said: “We’re really pleased to see such a positive set of results from our latest survey. Amid all the doom and gloom of the economy, rising petrol prices and maintenance costs, it’s great to know that drivers are more than capable of running simple car maintenance on their cars themselves.
“However, we would always advise motorists to seek professional advice and servicing for persistent or more complex problems with their cars.
"Similarly, regular maintenance and checks will help avoid more serious and damaging problems to a vehicle in the long run.”
