Although prices are falling, the RAC said drivers were still getting a “raw deal” at the pumps. Currently, motorists would be forking out 166.27p per litre for unleaded and 182.13p for diesel, with both prices expected to fall further.
With the sun still beaming down on the UK, and warm weather likely to remain for a while longer, drivers will be out and about before winter.
With the warmer weather, many motorists will often pick between having the windows open or using the built-in air conditioning.
While most may overlook their impact on fuel efficiency, both options have a huge impact on how the fuel is used.
Air con is very energy intensive and can use up a lot of fuel, especially on short journeys where it has to work hard to cool the car down.
Opening windows also takes a toll, as it increases the drag of the car, making the car work harder to move forward, burning more petrol or diesel in the process.
Chris Evans, head of content at Leasing.com, highlighted the benefits of using air conditioning while also having the windows open when driving.
He referenced a study by the Society of Automotive Engineers (SAE) from 2004, which looked at the impact of open windows against air conditioning in larger saloons and SUVs.
In the study, a number of variables were involved, including how open the windows were, the aerodynamics of the different cars and how long someone might use the air conditioning.

Commenting on the study, he said: “As such, the 45mph figure is a guide, but a fairly good one.
“While all this might seem like a minor issue, getting it wrong can have a notable impact on your fuel economy.
“Using AC can increase your fuel consumption by as much as 10 percent but opening the windows at higher speeds can increase fuel consumption by as much as 20 percent.”
Other studies have also been completed, including one which found that hybrid car fuel economy is more heavily affected by air con use than conventional combustion-only cars.

Drivers are advised to stick to a 45mph speed, where appropriate, but this can get tricky if there is traffic.
In these situations, Mr Evans said it would probably be best to avoid using air con or opening the windows.
He added: “However we know that in hot conditions that might be uncomfortable, so as a solution you could turn on the air con but close your air vents.
“The air con merely recycles the cabin air rather than drawing the air from outside, where there is nose-to-tail line of traffic all belching out exhaust fumes.”
This comes as supermarket petrol stations are set to close for Queen Elizabeth II’s funeral on Monday, September 19.
Tesco, Sainsbury’s, Asda and Morrisons will close forecourts on Monday before some reopen at 5pm.
Only a small number of Tesco petrol stations with self-service will reopen in the evening.
As a result, motorists have been advised to check their local pumps.
The “big four” supermarket petrol stations said they would be closing the petrol stations “as a mark of respect” to Her Majesty.
