More than a third of motorists are now carrying out their own servicing, but many are not confident about their abilities, a survey has shown.
As motoring costs, including car insurance premiums, continue to rise, many people appear to be considering self-service as a means of saving some money.
However, a poll of 2,000 drivers by automotive parts company Kwik-Fit found 69% were not sure they would be able to service their vehicles on their own.
People appeared to be more confident if they had an older car with less sophisticated electronics systems.
Among motorists owning a car from 1999 or earlier, 37% believed it would be easy for them to service. In contrast, only 6% of those with cars from 2007 to 2010 were as confident.
The study also revealed that a large number of vehicles were going completely unserviced.
Kwik-Fit customer services director David White said: "Modern cars are increasingly reliant on computer technology so there are fewer tasks under the bonnet suitable for an amateur enthusiast as they won't have the necessary equipment.
"Car owners shouldn't rely on the MoT to pick up faults as this mainly focuses on safety factors. A proper service will highlight issues which could cause a future breakdown and also cover areas too complicated for most DIY mechanics."
