Why Little Cars Are Ideal for Saving on Gas
Stepping down into smaller cars comes with an inherent advantage. They’re lighter, so the engine has a less strenuous time hauling them around. They are powered by smaller engines that consume less fuel. Their streamlined shapes cut air more effectively.
But many drivers never realize that potential. They rev their fuel-efficient vehicles as if they were a speedway. They skip basic maintenance. They carry unnecessary weight. Then they wonder why their gas mileage sucks.
The following pointers will correct that. Let’s dive in.
Tip 1: Learn Smooth Acceleration
Act like you have an egg under your foot here where the gas pedal is. Press too long and hard and you’ll break it. This psychological trick will help you master the single most important fuel-saving habit: easy acceleration.
When you slam on the gas pedal, your engine drinks gas to provide that surge. Small-car engines just aren’t designed for hard takeoffs. They’re designed for efficiency. Every time you punch it from a stoplight, you’re making your engine go against its own nature.
How to Accelerate Smartly:
First ease onto the gas gently. Count up to five in your head as you get up to speed. This slow pick-up consumes much less fuel than rapid acceleration.
Look ahead when entering onto the highways. Speed up at least a second in advance. Go faster as you enter the on-ramp, not at the end of it — so you can accelerate gradually instead of like a maniac.
Watch the cars ahead of you. If you know there’s a red light ahead, you’re not gaining anything by going as fast as possible and then coming to a stop. Coast whenever possible.
The Real-World Impact:
Aggressive driving can reduce fuel efficiency between 15-30% at highway speeds and 10-40% in stop-and-go traffic. For a small car that gets 35 miles per gallon, that’s the difference between 35 mpg and a possible 25 mpg. That amounts to hundreds of dollars wasted over a year of driving.
Tip 2: Steady and Sweet Keep Your Speed
Most small cars operate most efficiently at what mechanics refer to as the “sweet spot” – anywhere between 45-60 mph. This is where your engine runs at its most efficient, using the least fuel per mile.
Drag starts to skyrocket after 60 mph in the transmission of energy. Your tiny car has to work against the wind drag. Each 5 mph over 60 mph is like paying an extra $0.20 per gallon of gas.
Speed Management Strategies:
Use cruise control on highways. This keeps the pace steady, as opposed to the imperceptible accelerations and decelerations of your foot. Any speed variations, no matter how small, waste fuel.
When you can, stay in the right lane. The slower lanes simply encourage steadier speeds. And you also won’t feel the need to match faster traffic.
Try to take your trips at off-peak times. Traffic jam battles aside, it’s also a lot easier to keep the speedometer from jumping around.
The Numbers Don’t Lie:
| Speed (MPH) | Loss in Fuel Efficiency | Annual Cost Increase* |
|---|---|---|
| 60 | Baseline | $0 |
| 65 | -8% | $160 |
| 70 | -17% | $340 |
| 75 | -23% | $460 |
*Assuming 12,000 miles/year, 35mpg and $3.50 per gallon
Tip 3: Keep It Light and Get Rid of the Clutter
The more weight your car carries, the more fuel it needs to get moving. It’s basic physics. Smaller cars feel this power drain more than those larger in size due to having less starting power.
That gym bag you intended to bring inside for two weeks? It’s costing you money. Those books in the box labeled “Donations”? Also draining your tank. Even hitching up that roof rack you used for one camping trip last summer creates drag and reduces efficiency.
Weight Reduction Checklist:
Clean out your trunk completely. Take out all the garbage except your spare tire, jack and emergency kit. You’d be amazed at all the junk that can gather back there.
Remove roof racks and cargo carriers when not in use. Even when empty, they create wind resistance and can cut highway fuel economy by up to 5 percent.
Your car is not a portable storage locker. If you have not used it in your car for a week, bring it inside.
Check your gas tank strategy. There are those who prefer the security of a full tank in case of emergencies, but a full tank adds around 60 pounds over that of a quarter-full one. Wait until you get down to a quarter tank before filling up instead of always driving around on fumes.
The Weight Penalty:
For every 100 pounds of excess stuff you carry in your car, your fuel economy is reduced by about 1-2 percent. That may not seem like a lot, but if you’re lugging around 200 pounds of useless junk on the long haul, losing 2-4% efficiency all the time adds up. Over the course of a year, that’s 30-50 gallons of gas down the drain.
Tip 4: Keep Proper Tire Pressure
This is the simplest tip to apply and most forgotten. Your tires are the point of contact between you and the road. When they are under-inflated, your car has to work hard to roll forward.
It’s like pedaling a bike with flat tires. You drive with a lot more strain to get the same distance. The engine in your car has this battle with low pressure in the tires as well.
Tire Pressure Essentials:
Inspect your tire pressure at least monthly. Don’t eyeball them — tires can be well under inflated and still appear O.K.
Try an accurate tire pressure gauge. Digital gauges are affordable and more accurate than the old pencil-style.
Check pressure when tires are cold, meaning the car hasn’t been driven for at least three hours. Tires on cars heat up and pressure spikes temporarily when driven.
Know your car’s recommended pressure. You can find this information on a sticker located inside the driver’s door jamb, not printed on your tire sidewall. Max pressure is on there so you know what highest pressure, not the best pressure.
Inflate to recommended PSI, not maximum. Many people make this mistake.
Seasonal Adjustments:
Temperature affects tire pressure. Tires lose about 1 PSI for every 10-degree drop in temperature. In winter, you’ll have to check and adjust more often.
The Efficiency Boost:
Inflating tires properly can increase gas mileage by 3 percent. That seems small, but that’s free money. Simply spend a few minutes once a month checking pressure, and you’ll save $50-100 each year on an average small car.
| Pressure Status | Fuel Economy Impact | Safety Risk |
|---|---|---|
| Properly inflated | Optimal performance | Lowest |
| 5 PSI low | -1.5% efficiency | Moderate |
| 10 PSI low | -3% efficiency | High |
| 15 PSI low | -5% efficiency | Very high |
Tip 5: Schedule Your Maintenance Wisely
A well-tuned small car is an economical small car. There’s more than breakdowns at stake when you skimp on basic maintenance — slowly slipping away in the process is some of your gas mileage.
Oil Changes Are More Important Than You Realize:
Fresh, clean oil reduces friction in your engine. Less friction provides a smoother and more efficient running engine. Dirt and old oil will make everything harder than it already is.
Put the proper grade of motor oil in your car. Check your owner’s manual. The use of 10W-30 in place of 5W-20 can result in a loss of fuel economy.
Consider synthetic oil. It is more expensive upfront, but lasts longer and offers better fuel economy, especially in extreme temperatures.
Air Filter Attention:
If the air filter is dirty, your engine is being choked. It’s kind of like trying to breathe through a dirty sock. Your fuel burns best with air flowing at a certain level.
Inspect your air filter every six months. Hold it up to a light. If you can’t easily see light through it, swap it.
A clean air filter can boost acceleration and miles per gallon by up to 10% in older cars. The effect is greatly mitigated (1-3%) by modern cars with good engine management systems, but it’s still something.
Spark Plug Performance:
Worn spark plugs cause misfires. Each misfire wastes fuel. In the most extreme cases, bad spark plugs can decrease fuel economy by 20 to 30%.
Moreover, most small cars require replacing their spark plugs after every 30,000-100,000 miles, depending on the type. Check your owner’s manual.
The Maintenance Schedule Sweet Spot:
Don’t over-maintain or under-maintain. Just stick to the service interval recommended by your car’s manufacturer. They’ve engineered those gaps for peak performance and efficiency.
Tip 6: Learn How to Plan Your Trips Like a Pro
The greenest trip is the one you make while taking care of other errands. Cold starts consume much more fuel than warm engine operation. Your engine operates most efficiently at operating temperature.
Strategic Trip Planning:
Combine errands into one outing. Rather than making three separate trips throughout the day, tour your stops in a single loop.
Hit the farthest point first while your engine is cold and work your way back home. By the time you’re stopping around town multiple times, your engine is already warm and running efficiently.
Utilize mobile applications or maps to maximize the best route. Sometimes a route that’s longer by distance actually saves on fuel, because it can skip traffic lights, stop signs or congested areas.
Avoid rush hour when possible. The No. 1 enemy of fuel efficiency is stop-and-go traffic. If you can do your errands at 10 AM instead of 5 PM, that’s a lot of gas money saved.
The Cold Start Factor:
Your vehicle consumes twice as much fuel during the first 5 minutes of your drive than after the vehicle warms up. Several short trips during the day converts into several cold starts.
Remote Start Reality Check:
With remote start, resist the temptation to warm up your car for 10 or 15 minutes. Idling modern engines for 30 seconds before driving is sufficient. Running with extended warm-up times only consumes fuel and is not a service to your engine.
Idling Insights:
Idling gets you 0 mpg. And if you’re in line for more than a minute, turn off your engine. The fuel used to restart the engine is less than idling for a minute.
Most small modern cars come with automatic start-stop systems that stop the engine at traffic lights. Do not turn this off – it’s fuel saving.
Bonus Tips That Really Work
In addition to the six primary tips, here are some other strategies that could help you get every last ounce of efficiency out of your small car. For more comprehensive guidance on fuel-saving driving techniques, explore additional resources and expert recommendations.
Air Conditioning Wisdom:
AC can decrease fuel efficiency by 5-25%, depending on outside temperature and how hard the system works. Use it wisely.
At slower speeds (less than 40 mph), opening windows saves fuel over using AC. At highway speeds, closed windows with AC is more efficient because open windows create so much drag.
Park in shade when possible. A cooler car requires less AC to chill it out.
Reduce Drag Everywhere:
Close windows at highway speeds. Open windows produce turbulence that serves as an unseen parachute that slows you down.
Take off non-aerodynamic aftermarket accessories. Big spoilers, hood scoops, or poorly installed add-ons can hurt efficiency.
Keep your car clean. Dirt and grime adds little bits of drag. A clean car travels through air with less resistance.
Fuel Quality Considerations:
Use the manufacturer’s recommended octane rating. Nearly all small cars can get by just fine using regular unleaded. Premium is unnecessary when it’s not needed, and doesn’t make the car perform or run any better, just cost more money to operate.
Fill up at reputable stations. Low grade fuel can be inefficient and harm your engine.
Don’t top off once the pump clicks. There are no bonus squirts of it that get you more range – it just stores in other parts of the fuel system.
Tracking Your Progress
You can’t improve what you don’t measure. Begin tracking your fuel economy and experiment with which tips are most helpful for the way you drive.
Simple Tracking Method:
Reset your trip odometer when you fill up. Note the gallons purchased. On your next fill-up, take miles driven and divide by the gallons you bought. That’s your MPG for that tank.
Or you can stash a little notebook in your glove box or use a fuel tracking app. Watch for patterns. What did a week of highway driving reveal in terms of mileage? Did those aggressive commutes hurt your average?
A lot of today’s cars have a real-time fuel economy read-out on their dashboards. Take advantage of this and see real-time feedback on your driving habits.
Setting Realistic Goals:
Especially if your tiny car is designed to deliver 35 mpg combined and you’re only achieving 28, you’ve clearly got some way to go. Follow these guidelines and you should be able to match or even surpass the EPA estimates.
Don’t expect overnight miracles. Efficiency gains take time, as you work your way through how to use it more efficiently.
Common Fuel-Wasting Mistakes to Avoid
Drivers also frequently undermine their fuel efficiency with the best of intentions.
The “Jackrabbit” Syndrome:
It accomplishes nothing to gun a car down the road and have to brake a moment later, wasting vast quantities of fuel. Get in the habit of looking ahead and predicting traffic flow.
Premium Fuel Myths:
If your car doesn’t strictly need premium fuel, using it won’t help you at all. You’re just throwing money away.
The “Warm-Up” Waste:
Today’s cars do not require several minutes to warm up. In today’s fuel-injected vehicles, this is just an old routine used in carbureted engines to use excess gas.
Neglecting Basic Checks:
Dismissing dashboard warning signals, especially the check engine light, could be covering up issues that are reducing fuel economy.
Frequently Asked Questions
How much money can I realistically save using these tips?
These tactics save most drivers 15-25% on their fuel expenses. That’s $200-400/year in the pocket of someone driving a small car 12,000 miles annually and getting 30 mpg on regular at $3.50/gallon for gasoline.
Are fuel additives effective when it comes to gas mileage?
Most fuel additives give little to no measurable increase in MPG. Instead, concentrate on driving habits and maintenance. According to the U.S. Department of Energy, most additives don’t do what they claim.
Should I fill up my tank in the morning, when it’s cooler?
This is a persistent myth. Today’s gas pumps take temperature into account when computing fuel volume. Filling up at certain times of the day is not going to get you more gas.
What are the effects of weather on my small car’s fuel economy?
Cold temperatures can lower fuel economy 10 to 30 percent on short trips since engines take longer to warm up. High temperatures lead to a boost in AC usage, which can decrease efficiency by 5-25%. Mileage suffers at both ends of the temperature scale.
Will it help my car run better on premium gas?
If, and only if your owner’s manual says so. For most small cars, and many of the other ones, that is regular unleaded. Premium is a waste when not needed and it runs 20 to 60 cents per gallon more.
Can rolling down the windows reduce fuel economy?
Above 40-50mph yes. Roll down windows contribute to aerodynamic drag, which can decrease fuel economy by 5-15%. At lower speeds, open windows consume less fuel than A/C.
Your Fuel-Efficient Journey Starts Now
There isn’t anything particularly difficult about saving fuel. What it’s about is learning the way to drive your small car and the smarter ways you’ll learn to do so that eventually, they’ll become second nature.
Pick one or two pieces of advice that seem easiest to apply. Perhaps you’ll start by inspecting tire pressure this weekend. Or maybe you’ll work on smoother acceleration during your next commute. Once these habits are second nature, add another tip.
Small changes compound over time. That smooth acceleration recoups a few pennies per trip. Then there’s the small matter of correct tire pressure, which probably adds a few more cents. When you combine multiple such small savings with a consistent speed and intelligent trip planning, those pennies become dollars, and those dollars turn into hundreds of dollars in annual savings.
Your little car already has fuel economy in its DNA. These six tips just help you access that potential. There’s no need to own a hybrid or electric vehicle to save serious money at the pump. You just need to drive more intelligently, rather than harder.
The best part? Every gallon you help save is a gallon that doesn’t become exhaust. You’re not only saving money — you’re limiting the damage that you do to the environment mile by mile.
Fill your tank, reset your odometer and follow these tips. Compare your results after a couple of tanks and see your fuel economy rise. Your wallet will appreciate it and you could discover that relaxed driving is more relaxing than the rushed, aggressive tactics of most drivers.
The journey to better fuel economy begins now, on your very next drive.
