You spend a lot of money on a vehicle, the most money you'll spend on anything except a house. But the spending continues after you've bought it. It goes into things like insurance, repairs, and fuel. One good piece of news is that you can cut down the amount you spend on fuel if you follow a few tips.

Keep your speed under 50 mph/80 kph. Anything over that, your fuel economy will drop quickly the faster you go. You can legally drive faster than that, but practice this tip, saving you 7%-14% on fuel.

You can use cruise control. The steady speed increases fuel economy by avoiding unnecessary braking and accelerating. 

If your vehicle is carrying unnecessary weight, unload it. If you can save 100 pounds/45 kilograms, it can save you 1% of your fuel. 

Don't idle. Let's say you're sitting in a parking lot with your engine running for 10 seconds. Any more, and you're wasting fuel. Please turn off your engine and start it when you have to get going. You may have noticed that many newer vehicles automatically turn the engine off when the car stops.

Also, if you have roof rails on your vehicle with crossbars, you can save 1% of fuel simply by storing them somewhere else. Some cars, like Chrysler's Pacifica minivan, allow you to store the crossbars inside the roof rails to reduce drag.

Keep tires at their recommended inflation. It can save you 3% of your fuel bill.

Use the right motor oil for your vehicle. Using the wrong oil weight can cost you 1%- 2% more on fuel.

Sure, many of those savings are small on their own. But add them up, and you'd be surprised at how much you can save. Also, remember that a well-maintained vehicle will save you fuel, so make regular maintenance trips to your vehicle service facility.
