Drivers should avoid one button as it 'increases fuel consumption by 20%', warns expert
Amotoring expert has warned petrol and diesel drivers could waste up to 20 percent of their fuel tank by pressing one button as temperatures soar.
Simply opening car windows during periods of hot weather could be detrimental to motorists' fuel economy and use up more petrol or diesel, warns a specialist.
Chris Evans, head of content at Leasing.com has stressed drag from windows could have a negative effect on motorists' fuel tanks at top speed.
However, windows may be better than air conditioning at low speeds meaning drivers face a balancing act to get the most from their tanks.
Opening a window at higher speeds is likely to be less beneficial with Mr Evans suggesting that 45mph is considered to be the cutoff.
