Gas prices have jumped to their highest level in history so it’s more important than ever to save money at the gas pump.
You can do that if you tune up, slow down, lighten up, and use money-saving apps to find the least expensive gas near you..
How to squeeze more miles out of each gallon of gas
Tune Up
A properly tuned engine can improve fuel economy about 4 percent, according to the U.S. Environmental Protection Agency.
Fixing a serious issue – such as faulty oxygen sensor – can boost mileage up to 40 percent.
If you have a late model car equipped with a service-engine-soon light, don’t ignore the warning.
Pump Up
Properly inflated tires improve gas mileage up to 3 percent or more, plus properly inflated tires are safer and last longer.
Under-inflated tires can lower fuel economy by 0.3 percent for every one pound-per-square-inch drop in the pressure of all four tires.
Do not rely solely on the tire pressure monitoring system to detect an under-inflated tire; you should also check tires with a good gauge once a month.
Unpack
Turning your vehicle into an attic or garage on wheels makes your vehicle work harder and use more gas.
The EPA says an extra 100 pounds reduces fuel economy up to 2 percent, and even more in smaller vehicles.
A loaded roof rack cuts fuel economy by up to 5 percent.
Since about a quarter of each gallon of gas goes toward overcoming wind resistance, when cargo rides on top of the vehicle, fuel economy is reduced.
Even empty ski/snowboard or bike racks can affect aerodynamics, so remove them when the seasons are over, or in between the weekends when you are using them. Yes, it’s extra work – but it’s also extra savings at the gas pump.
Slow Down
While each vehicle reaches its optimal fuel economy at a different speed or range of speeds, gas mileage decreases rapidly at speeds above 60 mph.
According to the EPA, every 5 mph over 60 mph is like adding an additional 24 cents per gallon for gas.
Avoid Idling
Lucky you if you have a late-model vehicle with automatic engine shut-off at stoplights, because it saves gas.
A car gets zero mpg when the engine is idling. Even though it does take a small amount of fuel to restart a vehicle, 15 minutes in the drive-through can burn through a quarter of a gallon of fuel.
So that dollar menu is more like a $2 menu.
Chill Out
Speeding, rapid acceleration and braking can lower gas mileage by 33 percent on the highway and 5 percent in city driving.
Make believe there’s a raw egg under the gas pedal, so you accelerate gently,
Put it in Overdrive
Using an overdrive gear on the highway reduces engine speed, saving both fuel and engine wear.
Roll ‘Em Down Around Town
Air conditioning reduces fuel efficiency by up to 10 percent. Avoid using the air conditioner by rolling down the windows at speeds below 40 mph.
At speeds above 45 mph, wind drag uses more fuel than running the A/C.
Unclog
It’s hard to run if you can’t breathe.
Older cars without fuel injection and computer-controlled technology can lose 14 percent of their fuel economy because of a dirt-clogged air filter, which also can damage the engine.
An air filter full of dirt makes the engine work harder and can let in impurities that damage the engine.
Replacing a severely plugged filter improves fuel economy by up to 14 percent, according to the EPA. In modern cars, replacing a dirty or clogged air filter also improves acceleration performance
Use the Right Oil
Because oil reduces engine friction and friction makes an engine work harder, using the manufacturer’s recommended grade of oil improves fuel economy by 1 percent to 2 percent.
Plan your Trips
Taking your kids to soccer or swim classes? Grocery shopping? Plan routes and timing to avoid heavy periods of traffic congestion.
Cap Check
Loose or poorly fitting gas gaps can trigger a “check engine light” warning. Worse, they send 147 million gallons of gasoline into the air as vapor every year, according to a recent report by the Discovery Channel.
A missing or poorly fitting cap can reduce fuel economy by 1 to 2 percent.

Money-saving Apps
It could be worth driving a few miles to save money. These apps tell you – literally – where to go.
In no particular order –
Probably the best-known gas-price app, and one of the easiest to use. Set it with your zip code, and it finds the least expensive gas near you.
Similar to Gas Buddy, this app shows cheapest prices along your route, so you can decide whether to fill up near home or closer to your work. It also lets you save your favorite stations, and you can filter your search by the type of fuel your vehicle uses.
Waze.
You probably are using this app already for navigation, but might not be aware that it has gas prices built in.
If you are an AAA member, your membership includes access to this that lets you compare gas prices nearby. It could save you enough to cover the cost of membership.
This is all that’s left of the popular mapping app of a decade ago. What you’ll find here is a feature letting you compare gas-station prices.
This app provides rebates for gas, and has been widely advertised lately on national TV. Participating stations provide daily offers, but to get the rebates you have to photo and upload receipts, which may be more time-consuming than it’s worth, just to get cash or discounts, including on such services as car washes.
