1) Vehicle maintenance. Basic problems such as emissions can cause your car to use 4% more fuel than it should. More major problems can have a much more dramatic impact on this issue. If your oxygen sensor (the part designed to keep your engine running efficiently) is faulty, your fuel economy can drop by up to 40%. This is a huge deficit, and the longer it goes on for, the more money it will cost you. Regularly checking your car and repairing minor issues will also prevent you paying out when they turn into a huge issue.
2) Tyre inflation. You should regularly check your tyres are at the correct PSI. If you are unaware of what this is, check your car’s manual. Correctly inflated tyres mean your car has to put in less effort to move, thus saving you money. It is also safer to have fully inflated tyres; they give optimum turning and braking ability when they are full.
3) Speed. The harder you accelerate and the faster you go increases the revolutions your engine performs, which requires more fuel to power. Sticking to the speed limit and accelerating gently can save you a great deal of money on fuel.
4) Weight. Most people drive around with unnecessary items in their car. They might think it is helpful, but actually weighs the car down. This makes the car work harder to move, costing you more money on fuel. Your fuel economy is damaged by 2% for every 100 pounds of excess load you carry in your car. This issue is particularly bad for cars with a smaller engine.
5) Turn your engine off whilst idling for long periods of time. If you are stationary for a long time there is no point in wasting the fuel caused by leaving your engine on. This problem is particularly bad for larger cars that require more fuel to have their engine on.
Remember: If these tips don’t help, it may be your car that is the issue. There is a huge selection of fuel saving cars out there; you might find it more cost effective to change to one of these.
