What You'll Learn
Calculating fuel costs
To calculate the amount of fuel needed for your trip, you can use the formula: distance ÷ vehicle MPG x 4.546. This will give you an estimate of the fuel cost for your trip. Additionally, you can use your vehicle's MPG rating to compare the fuel efficiency of different vehicles. Choosing a vehicle with a higher MPG rating can help you save money on fuel over time.
There are also other ways to improve your vehicle's fuel efficiency and reduce fuel costs. For example, maintaining proper tyre pressure can reduce fuel consumption by up to 3%, while removing unnecessary items from the boot of your car can also help improve fuel efficiency. Driving at steady speeds, using cruise control, and reducing idling can also help maximise fuel efficiency.
Additionally, planning your route carefully and taking highways instead of local routes can help maximise fuel efficiency by maintaining steady speeds and reducing stop-and-go driving. Walking, biking, or using public transportation when possible can also help reduce fuel costs. Finally, choosing a smaller car with a less powerful engine can significantly reduce fuel costs compared to a larger vehicle.

Improving fuel efficiency
Maintain the right tyre pressure
Having the correct tyre pressure is essential for maximising fuel efficiency. Underinflated tyres create more drag, reducing the efficiency of your car. Regularly check your tyre pressure and top them up as needed.
Remove unnecessary items
Clear out any extra clutter from your car, such as sports equipment or heavy tools. The weight of these items can reduce fuel efficiency, and the more aerodynamic your car, the better its fuel economy.
Drive at steady speeds
Driving at steady speeds conserves fuel. Rapid acceleration and hard braking quickly eat up fuel, so driving smoothly and avoiding sudden stops and starts will improve fuel efficiency.
Obey speed limits
Most cars are most fuel-efficient when travelling between 50 and 80 km per hour. Above this speed zone, vehicles use more fuel the faster they go. Driving within the speed limit will help you save fuel.
Use cruise control
Using cruise control can help you maintain a steady speed, improving your mileage. This is especially useful for long drives or when driving on highways.
Take care of your engine
Changing your air filters regularly and ensuring all fluids are topped up will help your engine run smoothly and efficiently. Keeping your engine clean and well-maintained will also improve fuel efficiency.
Plan your trips
Minimise travel where possible and plan your trips to avoid congested areas. Longer trips also allow your vehicle's engine to warm up to its most fuel-efficient temperature.
Check fuel prices
Use apps and websites to check local fuel prices and find the best prices in your area. Generally, gas stations away from major highways and city centres tend to have better prices.
Keep a half-tank of fuel
During winter and when there's a risk of fuel shortages, keep at least a half-tank of fuel. This will give you flexibility and reduce stress when it comes to refuelling.

Choosing fuel-efficient vehicles
When choosing a vehicle, opting for a fuel-efficient model offers multiple advantages. Fuel-efficient cars typically require fewer trips to the petrol station, which can translate to significant long-term savings, especially with the high fuel costs often seen in the UK.
There are several ways to improve the fuel efficiency of your vehicle. Firstly, ensure you have the right tyre pressure. Underinflated tyres cause more drag and decrease how efficiently your car runs. Remove any unnecessary items from the boot of your car, such as sports equipment or heavy tools. Regular oil changes are also important; when oil gets too dirty, it can reduce engine performance and lead to decreased fuel efficiency. It is recommended that you have an oil change every 6 months to keep your engine clean and operating optimally.
When driving, maintaining a steady speed will help conserve fuel, as accelerating quickly uses up more fuel than when acceleration occurs slowly. Driving at higher speeds can decrease your fuel efficiency, so try to keep your speed below the posted speed limit. Using cruise control on long drives can also help save fuel by maintaining consistent speeds and avoiding sudden starts and stops.
When purchasing a new car, there are several options for fuel-efficient models. The most fuel-efficient engines are generally petrols with hybrid assistance and some newer diesel engines, especially on longer journeys. However, normal petrol engines can also be fuel-efficient, thanks to modern turbochargers and hybrid technology.
Some of the most fuel-efficient cars on the market include:
- BMW 330e plug-in hybrid, which can run on pure-electric power for around 30 miles and offers powerful acceleration and impressive economy.
- Toyota Prius, which offers both self-charging and plug-in hybrid versions, with the latter providing an impressive 235.4mpg.
- Hyundai IONIQ, a plug-in hybrid with a 1.6-litre petrol engine and electric motor, allowing up to 39 miles on a single charge.
- Toyota Corolla hybrid, available in both estate and hatchback body types, offering up to 62.8mpg.
- Mercedes-Benz E300de, a plug-in hybrid with a diesel-electric powertrain, offering a claimed economy of up to 201.8mpg.

Planning fuel-efficient routes
Planning a fuel-efficient route is a great way to save money and reduce your environmental impact. There are several factors to consider when planning your journey to ensure you are being as economical as possible.
Firstly, it is important to know your vehicle's MPG (miles per gallon) rating. The MPG rating indicates how many miles your car can travel per gallon of fuel, and the higher the rating, the more fuel-efficient the vehicle is.
Secondly, consider the terrain of your journey. Hilly regions will require more fuel, so it may be worth looking for routes with fewer elevation changes. Additionally, road surface conditions can impact fuel efficiency, with uneven or unpaved roads requiring more power and, therefore, more fuel to maintain speed.
Real-time traffic updates are also essential for fuel efficiency. By avoiding congested areas, accidents, and road closures, you can reduce the amount of time spent accelerating and decelerating, which can decrease fuel consumption.
When planning your route, try to minimise the number of stops. Your car is more fuel-efficient when making one long round trip than several short trips, as the engine operates more efficiently when it is warm. If you can, plan your stops so that the engine remains warm, and try to avoid leaving the engine idling for extended periods, as this wastes fuel.
Finally, ensure your vehicle is in optimal condition before setting off. Check your tyre pressure and keep your engine well-maintained with regular oil changes and air filter replacements. Remove any unnecessary items from your boot, as extra weight can decrease fuel efficiency.

Maintaining fuel-efficient driving habits
Maintain proper tyre pressure
Check your tyre pressure regularly and ensure your tyres are properly inflated. Underinflated tyres cause more drag and decrease your car's fuel efficiency. The right tyre pressure for your vehicle can usually be found on the tyre information placard, often located on the edge of the driver's door or doorpost.
Remove unnecessary weight
Remove any unnecessary items from your car, especially heavy ones like sports equipment or tools. The heavier your car, the harder the engine has to work, which decreases fuel efficiency.
Drive at a steady speed
Driving at a steady speed helps conserve fuel. Accelerating quickly uses more fuel than accelerating slowly over time. Try to avoid speeding up and slowing down unnecessarily, and stick to the speed limit. Most cars are most fuel-efficient when travelling between 50 and 80 km per hour.
Use cruise control
Cruise control helps you maintain a constant speed, which improves fuel efficiency. It's especially useful for highway driving, where conditions permit.
Turn off your engine when stopped
Idling your vehicle for extended periods wastes a lot of fuel. Turn off your engine when you're stopped for more than 60 seconds, except when in traffic.
Keep your vehicle in good condition
Regular oil changes, clean air and fuel filters, and proper tyre alignment are essential for keeping your vehicle in optimal condition. Dirty oil and clogged filters can reduce engine performance and fuel efficiency.
Plan your trips
Organise your activities so that you can carry them out in a single trip, reducing the number of kilometres driven and your overall fuel consumption.
