How To Save On Car Fuel Costs - The Ultimate Guide

| In Motoring Advice

In the last few months, the price of fuel has skyrocketed. According to the RAC, on the 1st July 2022, the average price of unleaded fuel in the UK was 191.43p and the average price of diesel fuel was 199.07p. Although the current price is expected to fall, people are looking for alternatives and ways to save fuel. 


Here are a few tips and tricks to help save on fuel costs and make your car more fuel efficient. 

8 Tips To Help You Save Fuel

1. Keep Your Car Maintained 

Keeping your car in the best condition can help to improve its fuel efficiency. Although the yearly MOT can help, there are a few other simple maintenance jobs that can help improve the efficiency even more. 

  • Make sure that your tyres are pumped up with the correct pressure. If you're not sure what PSI your tires need, this can be found in the handbook or a sticker on the inside of the door. 
  • Make sure that there is the right amount of oil. Once the engine is cool, dipstick the oil level and top up if needed. 

2. The Right Gear 

Being in the correct gear for your speed can massively increase your mpg. Don’t over-rev your car but don’t be in too high of a gear for your speed. Petrol cars should be changed up a gear at 1500 to 2500 RPM. A diesel car should be changed up a gear at 1300 to 2000 RPM. Smooth acceleration and deceleration can also impact your MPG. 

3. Climate Control 

Having your air conditioning or heating on in your car can have an effect on your miles per gallon. When driving at a slow speed, open your window rather than having your air conditioning on. When it’s colders, dress warmly rather than having the heating on.

4. Cruise Control 

If your car has it, turn on the cruise control. By turning on the cruise control, not only are you adhering to the speed limit, you're actually saving yourself fuel. According to Evans Halshaw, by only travelling 10mph above the national speed limit, you are using 10% more fuel. 

5. Weight 

Lighten up the load in your can, remove any unnecessary items and remove the roof rack if you don’t use it all that often. Anything from spear shoes to bikes are adding weight and decreasing your MPG. Even the weight of fuel decreases your MPG. According to Cinch, you could save 1% of your consumption when you only half fill your car. 

6. Automatic Stop/Start

If your car has it, turn on the automatic stop/start. According to, people in the UK spend more than 28 hours every year in stationary traffic. If you are based in London, this is increased to 74+ hours. Having the automatic stop/start turned on cuts off the engine when the car is stopped and restarts when the brake is released or the clutch is pressed. This can help to save fuel and also help to reduce emissions. 

7. Parking

When parking, pulling forward into a parking space can actually improve your fuel economy as this avoids manoeuvres.

8. Momentum 

When at a set of lights that are just about to change or at a roundabout with a clear space, try and keep rolling where possible. If you have ever tried to push a car, you’ll remember how difficult it is. It’s similar for the engine. Continuing to roll allows your engine to work not as hard, improving your MPG.
