I know you love your truck. But you probably don’t love the $75 price on the pump after filling the tank. Ouch.
But for truck and large SUV drivers, there’s good news: the bigger your vehicle, the bigger your potential savings. Improve your gas mileage by a third in a 40-mpg Prius, and you might save $250 a year. Do that in a truck and you save way more.
If you make a few simple changes to your driving style and boost your fuel economy from 14 mpg to 20 mpg, you’ll save $15 on your weekly fill-up. By the end of the year, you’ll be $811 richer.
In California, with gas over $4 a gallon, those changes will save you $24 a week and $1,248 each year. Now that’s real money.
Does it really work?
Some years ago, when gas prices spiked and drivers were freaking out, I headed to a remote highway near Death Valley, California, with another automotive journalist to see what gas saving tips really worked. We took two cars and spent three days driving around a lonely 55-mile loop.
A few years later, we repeated the tests with three drivers, three different vehicles, on a different route. It was boring — but the results were exciting.
If you put all these tips together, you could boost your fuel economy by 37%. Here’s your road map to savings.
Tip 1: Relax
Far and away, the biggest gas waster is mashing the gas pedal from a dead start.
I can almost hear your subconscious shriek: “But it feels so good!” As a car guy, I don’t deny that. But if it’s draining your bank account, do it less often, or when you really need to, like when merging onto a freeway.
If you become a relaxed driver — easy acceleration, lower cruising speed, light braking — you can boost your fuel efficiency by as much as 37% based on fuel economy tests I ran in a remote section of California.
Tip 2: Use cruise
When you do a lot of highway driving, it pays to use cruise control. Set it at a reasonable speed and chill.
Setting cruise control makes you less likely to make sudden high-speed accelerations that not only guzzle gas but also attract the attention of the law. By staying in your lane (within reason) and driving at a constant speed, our tests estimated you can save up to 14% over the lane-changer who floors it to get around the slowpoke up ahead.
Tip 3: What’s the hurry?
Ask yourself this — how would you feel if you got there a little later, but when you arrived, someone handed you a $10 bill? That’s basically what you’re doing when you take it easy. And our tests proved that. Slowing down from 75 to 65 mph increased fuel economy up to 14% in the vehicles we tested.
Aerodynamics affect fuel economy exponentially. That means that increasing your cruising speed from 70 to 75 mph uses a little more gas. Going from 75 to 80 mph uses more gas. And going 85 uses a lot more gas.
Tip 4: Shut ’er down
Ever notice how drivers will see a friend, pull over and have a nice long chat while the motor is still ticking away? If you have lots of friends you like to visit while in the truck or SUV, and you find the hum of the engine comforting, you’re increasing your fuel consumption by about 10%. Shut it down, and it saves that much.
Tip 5: Streamline your ride
This one is for SUVs and other family haulers. Adding a roof rack doesn’t hurt your fuel economy much. But when we added a suitcase and cooler to the rack, the miles per gallon of our test SUV dropped from 27.2 to 21.6 — a loss of 21%. Moral of the story: Fit it inside or get a streamlined cargo carrier. It will pay for itself in no time.
Do your own tests
These days we have fuel economy information right under our noses to help us stay within our automotive budgets. Most cars have fuel-economy calculators as standard equipment, displaying both current and average miles per gallon. You can reset these each time you get gas and see your efficiency rise as you become better at using these tips.
I’d even recommend keeping a small notebook in the door pocket and logging each tank and the mileage you get. Or, you can go old school and check your mileage by dividing the miles you’ve traveled by the number of gallons you take to fill the tank.
When gas prices soar, I often hear people saying it’s time to buy a hybrid. That’s an expensive way just to avoid sticker shock when you fill up. Instead, stick with the truck, drive smart and save.
