6 Awesome Tweaks & Upgrades To Improve Fuel Efficiency

Most motorists think they’re stuck with the fuel efficiency that comes with the car. Not true. You can actually squeeze quite a few miles-per-gallon out of the car on your driveway. You might think that ‘mods’ and upgrades are strictly for boy-racers. But, we’re not talking about fuel injections and nitrous tanks. We’re talking about simple, sensible upgrades that improve the all-round efficiency of the vehicle.

Most are relatively affordable, and will save you a sizeable chunk of money in the future. Your fuel costs will come down significantly, and you’ll spend much less time at the mechanic’s garage. Most drivers don’t realise how effective these simple tricks are, and they needn’t take long to install. Without further ado, let’s take a look at the most fuel-efficient upgrades you can make.



  1. New Tyres

Your tyres have an incredible effect on fuel efficiency for all sorts of reasons. First of all, new tyres are optimised for perfect grip. It gives them a better response on the road, and means the engine doesn’t have to work so hard to drive them. Firestone tyres are the perfect example of these ultra grippy and high-mileage tyres. By optimising the surface area on the road, you’ll stretch the miles out, and secure a better efficiency. It’s also a good time to check your tyre pressure. When your tyre pressure is too low, it works the engine much harder. Imagine pedalling your bike on flat tyres. It’s a lot harder work, and that’s exactly how your engine feels on flat tyres.

  1. Upgrade the Onboard Computer

Nowadays, a lot of modern cars come with sophisticated onboard computers. However, these can be tweaked and upgraded to specifically measure your fuel consumption. The smartest new computers will automatically make engine tweaks and adjustments to improve efficiency. They’ll monitor your power distribution, and make sure the engine is working at optimum capacity. Ask your local mechanic about whether your car is likely to benefit from a tuned-up computer.

  1. Lose some Weight

When it comes to fuel efficiency, it’s all about simple physics. Your engine has to work much harder to pull a heavy load. Going back to our bike analogy, try putting an extra person on the back of your bike, and you have to work a lot harder. Add that to a flat tyre, and you’re really going to struggle! Take out any unnecessary things you’re keeping in the boot or backseat. Then ask your local mechanic if they can strip any useless parts from the car. Every little helps.

  1. New Spark Plugs and Wires

Here’s the simplest and cheapest option on the list. In fact, you could do this one in less than an hour or two. The spark plugs are buried just to the side of your engine, and they’re responsible for creating the initial spark of energy. When you turn your key in the engine, the spark plugs fire up, and get the engine going. When you replace your spark plugs, you make this process cleaner and more efficient. They cost almost nothing, and they simply screw into place.

  1. Replace your Filters

If you’re not familiar with how an engine works, here’s what happens underneath the bonnet. The engine takes in oxygen from the air outside. It combines that oxygen with fuel to create a combustion. It’s this combination that creates energy and powers the car. Now, in order for the engine to efficiently combine oxygen and fuel, it needs a quick flow of air. That’s where the filters come in. They remove dust particles and dirt from the oxygen to make sure it’s clean and efficient. When those filter clog up, oxygen can’t pass through quickly, and the engine uses more fuel. The simple answer? Replace your dirty air filters. Again, they’re cheap, and they simply slot into place next to the engine.

  1. Use Better Fluids

If you look in your car’s handbook, it will advise the use of specific and optimised fluids. Rather than putting plain water in your coolant tank, use an anti-freeze coolant alternative. It will keep the engine at the most efficient temperature, and keep things from overheating. Likewise, you can buy optimised oil that will improve the flow of mechanics inside the engine. Remember, the smoother the process, the less fuel you’re using. Don’t skimp on these simple extras, as they’ll pay for themselves in just one week of driving.

Most drivers don’t realise they’re paying far more than necessary on their fuel. Take this advice, and be a smarter driver!
