E10 fuel economy: Drivers warned to conserve petrol by managing revs – how to save money

Since its introduction at the start of September, E10 petrol has divided drivers of its implementation, with some praising the environmental benefits, and others complaining of their car not being as efficient. Using E10 petrol can slightly reduce fuel economy, with a reduction of around one percent, but it is unlikely to be noticeable in everyday driving.

Other factors, such as driving style or driving with under-inflated tyres, have a much more significant impact on fuel economy than using E10 petrol.

Helen Robinson, Corporate Communications Director at Euro Car Parts, commented on the efficiency debate and advised drivers to make the most of their petrol.

She said: “Driving more economically can save a lot more fuel and money than many motorists may realise.

“By following these tips not only are you kinder on your wallet, but you’re also helping to save fuel and cut down on unnecessary emissions.”

Managing your revs

When driving, many drivers fail to look at the revolutions per minute (RPM) count when changing gear, relying on the sound or feel of the engine, but drivers could be over-revving.

The most fuel-efficient RPM to change up a gear is 2,500 for a petrol car and 2,000 for diesel.

Staying above 1,500 revs in petrol and 1,300 in diesel cars should comfortably avoid dropping the revs too low, as this could cause unnecessary strain on the engine and waste fuel.

Strike the right balance with air conditioning

Using air conditioning can increase fuel consumption by up to 10 percent, but at higher speeds, opening windows will create wind resistance and decrease efficiency.

While stationary or at low speeds, drivers should try to use their windows to keep cool and save the air con for use on the motorway.

In colder temperatures, drivers are also advised to dress appropriately so they don’t need to use heat setting as much.

Drive at one speed through speed bumps

Acceleration and deceleration whilst driving can mean extra fuel is used, and this includes driving over speed bumps.

By driving over them properly, motorists can save a lot of money.

Drivers can avoid unnecessary fuel consumption by driving at a constant speed and avoiding accelerating or braking too often in between speed bumps, which is when most fuel is used.
