Motorists are being urged to squeeze as many miles out of their tanks as possible amid the fluctuating cost of fuel and our current cost-of-living crisis.
With fuel prices and living costs at record highs, households are looking to cut their monthly expenses and improving fuel efficiency is a good way to help stretch the budget.
Obviously, motorists are advised to avoid expensive petrol stations and search for the cheapest prices. For example, it may be more cost effective to fill the tank at an independent retailer, so best check online for the nearest locations before setting off and include them as part of an upcoming journey before the fuel level hits low.
One of the most crucial factors on fuel consumption is speed, as faster driving wastes more fuel. The optimal fuel-efficient speed for most cars is 72-80mph. However, on many journeys this can be very difficult, and it can be very frustrating for the traffic behind too.
However, it is a fact that speed increases fuel consumption. Figures show that driving on the motorway at 80mph (129kph ) uses around 25 percent more fuel than driving at 70mph (113kph ). Travelling at 70mph (113kph ) instead of 60mph (97kph ) will use nine per cent more fuel, and an additional five per cent more than driving at 50mph (80kph ).
Here are their top eight fuel saving tips:
Remove excess weight: The heavier the car, the harder the engine has to work, resulting in higher fuel consumption. Make sure to declutter your car and clear out the boot to reduce some weight.
Regular maintenance: Keeping the car in good condition ensures the vehicle runs efficiently which also helps fuel economy. It may be a bit costly to service the car, but it can save a lot of money in the long run.
Drive smoothly: Sudden braking and speeding up burns more fuel and that is why it is important to gauge the flow of traffic. Gentle acceleration and steady speed ensure the most economical use of fuel. Additionally, a note for electric car drivers, relying on regenerative braking will also help maximise driving range and the lifespan of mechanical brakes.
Change gears as early as possible: Switching into the highest possible gear keeps the revs low which saves petrol. For example, at a 40mph speed the car will consume 25 percent more fuel in third gear compared to fifth. Under normal conditions the gears should be changed when the revs are between 1,500 to 2,000 rpm.
Check tyre pressure: It is important to make sure the tyres are inflated to the right pressure, because under-inflated tyres create more rolling resistance which means that the engine has to work harder. The car can consume five per cent more fuel for every 0.5 bar drop in pressure. Also, tyres will last longer. The wrong tyre pressures can also affect a car’s braking performance.
Avoid idling: Drivers should not leave the engine running while they have stopped because it is bad for the environment and wastes fuel. It is worth switching off the engine when the car is stationary for even a few minutes.
Turn off additional functions: The vehicle’s add-on functions, like air conditioning and seat heaters, should only be used when necessary. The same goes for the heated rear screen, demisters and headlights. If you do not need them, switch them off, as they drain the car’s battery as well as the petrol tank. However, don’t neglect air-conditioning as systems sometimes have a tendency to develop mould or fail due to cracked seals if left unused for months on end.
Don’t fill the tank to the brim: Fuel is heavy, so if the tank is filled to the top, then there is more unnecessary weight that the car has to carry.
And here are some additional tips that come to mind: Do not leave roof-racks, roof-boxes, etc, on having finished using them for road trips. When they are in place, the extra wind drag will cost kpl/mpg. Also, opening car windows can also cause significant drag, so it could prove more economical to use the air conditioning to keep cool when driving at higher speeds.
Avoid buying more expensive premium/super unleaded petrols or more expensive super diesels. The promised higher-octane rating or additives do little or nothing for the vast majority of cars. However, some high performance or imported sports cars may have a recommendation for higher octane fuel. Also, because of the higher ethanol content these days in regular petrol, drivers of many old car may need to opt for premium unleaded. Check with a regular car service outlet.
And finally, as the winter months approach, do not turn on the engine at home in the mornings to de-ice and warm it up. It is better to drive the car gently immediately after turning it on, rather than leaving it to warm up. Not only will the engine warm up more quickly, reducing the potential for engine wear, it will use less fuel in the process. If the car is iced over, use an ice scraper or de-icing spray rather than leaving the car running and relying on the heating. Also, do not use very hot water to clear ice from the windscreen or back window as it can damage your wipers.
