Gas Is Up and Winter Is Coming. Here's How to Keep Your Fuel Bill Down.

Published on Sep 28, 2026 by Gianni (Jack) Young

Buckeye Toyota Service · Lancaster, Ohio

Gas costs a lot more than it did a year ago, and in a few weeks your car starts burning more of it.

You can’t do anything about the price or the weather. You can do something about how much of both ends up on your fuel bill. Here’s what’s worth doing this week, what’s worth doing once it’s cold, and what to know first if high gas prices have you looking at a hybrid.

Where your fuel bill stands right now

Columbus-area regular was running about $4.30 a gallon at the end of September, according to AAA. A year earlier it was about $2.90.

For a car that averages 25 mpg over 13,500 miles a year, that works out to about $63 more every month than last year, for exactly the same driving. Over a full year it’s roughly $2,322 in gas instead of $1,566.

Then winter adds its own increase. The Department of Energy puts a gas car’s city fuel economy about 15 percent lower at 20 degrees than at 77, and Lancaster’s normal January low, per NOAA, is about 21. The federal test temperature is just an ordinary January weekday here. That same 25 mpg car drops to about 21 in town, which adds roughly another $102 across December, January and February, on top of the higher price.

You don’t control the price or the weather. You do control a fair amount of what they end up costing you.

Prices as of September 28, 2026, and they change weekly. All the dollar math on this page uses $4.30 a gallon. The winter figure assumes mostly in-town driving, which is where DOE’s 15 percent applies. Highway-heavy commutes usually lose less.

Why winter makes it worse

Cold weather raises your fuel bill in eight separate ways, per the Department of Energy, which is why the total catches people off guard: eight small losses, stacked on top of each other. Half of them you can’t touch. The other half is where the savings are.

Physics

Nothing to fix

Cold engine oil and drivetrain fluids are thicker, so more of the engine’s work goes into turning its own parts.

Colder air is denser, which adds aerodynamic drag, mostly at highway speed.

Winter-blend gasoline can carry slightly less energy per gallon than summer fuel.

A cold battery is harder to keep charged, which works the alternator harder and, on hybrids, weakens regenerative braking.

Partly up to you

Where the savings are

The engine takes longer to reach its efficient temperature, and a short trip may never get there. How you group your driving.

Idling to warm the car up gets zero miles per gallon. That’s DOE’s phrasing, not ours. How long you sit in the driveway.

Heated seats, defrosters and blower fans all draw power the engine has to make. Which heat you use.

Tire pressure falls with the temperature, and underinflated tires roll harder. Whether you check.

None of the causes in the first list means something is wrong with your car. That’s worth knowing, because a lot of January mileage worry is just physics doing what it does every year.

How to keep your fuel bill down, starting now

In order of when to do it. The first few are worth doing this week, while it’s still mild. The rest are for the mornings when the cold shows up. Each one carries our estimate of what it’s worth, including a couple that are worth less than you’ve been told.

This week, before the cold

Set your tires now, then check them again after the first freeze

0.6% in fuel, 4,700 miles in tire life

AAA puts the drop at about 1 psi for every 10 degrees. Set your tires on a 75 degree afternoon like the ones we’re still getting, and by a 21 degree January morning they’re running around 5 psi low. Nothing is leaking. The air inside just contracted, and a tire that low still looks normal.

On the fuel side, the number is small. The Department of Energy’s current figure for proper inflation is 0.6 percent on average, far below the 3.3 percent you’ll still see quoted. The better reasons are tire life, where NHTSA puts proper inflation at 4,700 extra miles, and grip on a cold, wet road.

Two details matter. Check them cold, meaning the car hasn’t been driven for three hours, or the reading comes out high. And use the pressure on the sticker inside the driver’s door, not the number molded into the tire, which is a maximum. If the low-pressure light comes on in the morning and goes off once you’re driving, AAA’s advice is that the tires are still low. Stop by the service drive on Riverway Drive and we’ll check them at no charge. Our tire service page lists everything a full inspection includes.

Make your next oil change the right grade for cold weather

1 to 2%

DOE’s cold-weather list includes this one by name. A heavier grade than the manual calls for costs 1 to 2 percent, and cold oil is one of the eight causes above. Many newer Toyotas call for a very thin 0W oil, which flows more easily on a cold start. Not sure what yours takes? The oil change page has the details.

Real savings, no honest percentage

This is the one item on the page that could be an actual fault costing you fuel. A failing sensor or a misfire does burn extra gas, and either one often triggers the light. You’ll see confident percentages online for what fixing them saves. The Department of Energy withdrew those figures, so we won’t quote one. It’s just a lot easier to sort out on a mild October afternoon than in a January parking lot, and our service team can tell you what the code means.

If you’re buying winter tires, buy them for grip, not gas mileage

Not a fuel decision

You’ll see claims both ways about what winter tires do to mileage. We couldn’t find a federal or independent testing source that put a reliable number on it, so we won’t give you one. If you get them, get them because they stop and turn better on snow and ice. That part isn’t in dispute.

Every cold morning

Give it 30 seconds, then drive gently

$7 to $18 a winter, and heat sooner

The Department of Energy’s guidance is that most manufacturers recommend driving off gently after about 30 seconds. An engine warms up faster being driven than sitting still, so the heat comes on sooner, and a long idle stretches out the exact cold phase that’s costing you fuel.

The money here is modest. Argonne National Laboratory’s idle figures work out to roughly 11 to 28 cents for a ten-minute warm-up, or about $7 to $18 across the weekday mornings of December through February. Warm it up again before the drive home and double that.

The real exception is ice on the glass. Clearing your windshield completely is a safety requirement, not a fuel decision. Defrost it, then go. If you drive a Toyota hybrid, the Prius owner’s manual says warming up is unnecessary, because the hybrid system runs the gas engine on its own as it needs to.

Park in the garage if you have one

A free head start

It’s on DOE’s short list of cold-weather tips. An engine that starts the day warmer gets through its least efficient phase sooner, and the cabin heat arrives sooner too. Nobody has published a percentage for this, so we won’t make one up. If the garage is still full of summer, this is the month to fix that.

Know which heat is the cheap one in your car

Depends on what you drive

In a regular gas car, the heat itself is nearly free. Cabin heat is waste heat pulled off the engine’s coolant, and the engine makes it whether you use it or not. Apart from the blower fan, you aren’t paying extra for it. Heated seats and defrosters are electrical loads the engine burns fuel to supply, which is why DOE’s advice is not to run them more than necessary. The popular tip to use the seat heaters instead of the heater to save gas is backwards in a gas car.

In a hybrid, the heat isn’t free. The Prius owner’s manual explains that in cold weather the gas engine won’t shut itself off until both it and the cabin are warm, and to avoid overusing the heater. Cranking the heat all the way up keeps the engine running at exactly the moments a hybrid would normally be saving you fuel. A slightly lower setting lets it get back to doing its job sooner.

In a plug-in hybrid or an EV, the old tip finally holds. DOE recommends seat warmers instead of heating the whole cabin, and warming the cabin while the car is still plugged in, so that heat comes from the wall instead of the battery.

Every week, all winter

Chain your cold starts together

Up to 24% on short trips

Of all the winter habits, this one is worth the most. The Department of Energy puts the cold-weather penalty on short trips of three to four miles at as much as 24 percent, against about 15 percent for city driving in general, because the engine never finishes warming up. DOE’s advice is to combine trips so you drive less often with a cold engine.

In practice that means making the stops on the way home, while the engine is already warm, instead of heading back out from a cold driveway after dinner. The grocery run, the pharmacy and the post office in one warm loop cost noticeably less than the same three stops made from three cold starts.

If gas prices have you looking at a hybrid

Know this before winter: hybrids lose more in the cold than gas cars do

A lot of people are shopping hybrids this fall because of what gas costs, and the instinct is right. Here’s the part that rarely gets mentioned, from people who sell a lot of them.

The Department of Energy puts a gas car’s cold-weather city loss at about 15 percent. For a hybrid it’s about 30 to 34 percent. Roughly double.

The reason is where a hybrid’s advantage comes from in the first place: the gas engine shutting off when it isn’t needed, and regenerative braking catching energy that would otherwise turn into brake heat. Cold interferes with both. The engine has to keep running to warm itself and the cabin, and a cold battery accepts a charge less readily, so braking recovers less.

A typical 22 mpg gas SUV
Rated22 mpg
Cold-weather lossabout 15%
In Januaryabout 18.7
2026 RAV4 Hybrid AWD LE
Rated42 mpg
Cold-weather lossabout 32%
In Januaryabout 28.6

The hybrid gave up more than twice as much in percentage terms, and it’s still getting more than 50 percent more miles per gallon on the same January morning. Run both through December, January and February at those January numbers and the hybrid burns about $268 less in fuel. In winter, the gallons tell you more than the percentages do.

So if you buy one this fall for the fuel savings, the savings are real. Just expect the number on the dash to dip in January. Short trips hit hybrids hardest, 25 to 45 percent in DOE’s real-world range, because the engine may run the whole time. And if your average falls by a third, it’s most likely the season, not a fault. It comes back when the weather does.

EVs feel it most. AAA’s testing found range down 41 percent at 20 degrees with the heater running, but only 12 percent with it off, which means most of an EV’s winter loss is cabin heat, not the battery. That’s why warming a bZ or a plug-in hybrid while it’s still plugged in matters so much.

This winter: is it the cold, or is it the car?

Most January mileage drops are the physics list above. A few aren’t. Here’s how to tell them apart, and the first test is free: compare this January with last January, not with September.

Probably just winter

It slid gradually as the temperatures did.

It’s worst on short trips and cold mornings, and better on long drives.

It’s roughly where it was last January.

No warning lights, and the car drives normally.

Worth having us look

It dropped suddenly instead of gradually.

The check engine light is on. Many faults that cost you fuel will light it.

The tire pressure light stays on after you’ve been driving a while.

It pulls to one side, runs rough, or a wheel smells hot after a drive.

If it’s the second list, schedule a visit or call our service team at (740) 402-3424. We’ll tell you which one it is, including when the answer is just January.

The biggest lever on your fuel bill is the car itself

Everything above keeps the price and the cold from taking more than they have to. But if you’re driving an older gas vehicle, the biggest lever is what it burns to begin with. Winter takes its percentage either way. The question is a percentage of what. And on the Toyota side, that picture changed this year.

For 2026, the RAV4 and the Camry are hybrid-only. There’s no gas-only version of either one anymore. The EPA rates the base RAV4 at 43 mpg combined and the Camry LE at 51. The efficient version is now the only version.

That 25 mpg car from the top of this page could easily be a 2015 RAV4.

A 2015 RAV4 AWD at 25 mpg combined
13,500 miles ÷ 25 mpg = 540 gallons
540 × $4.30 = $2,322 a year in fuel

A 2026 RAV4 Hybrid AWD LE at 42 mpg combined
13,500 ÷ 42 = 321.4 gallons
321.4 × $4.30 = $1,382 a year in fuel $940 a year. About $78 a month. 219 fewer gallons.

Take out Ohio’s $100 yearly hybrid registration surcharge and it’s still about $840. And in January, using DOE’s cold-weather figures, the 2015 lands around 21 mpg while the new one lands around 28.6. Winter takes a bigger bite out of the new one, and it still comes out about a third ahead.

Need three rows? The EPA rates the Grand Highlander Hybrid AWD at 34 mpg combined, against 23 for the gas Grand Highlander with all-wheel drive. That’s close to 50 percent more, carrying the same people.

A newer vehicle means a payment, and that’s part of the math. The figure that decides whether it works is what your current vehicle is worth today, and that’s the one number no article can hand you.

EPA combined ratings at 13,500 miles a year and $4.30 a gallon. January figures apply DOE’s cold-weather city losses of about 15 percent for gas and 32 percent for hybrids, and are illustrative. Real-world Ohio winter results vary. Federal clean vehicle tax credits are not available for vehicles acquired after September 30, 2025.

Questions we’re hearing this fall

How much does cold weather lower gas mileage?

The Department of Energy puts a conventional gas car’s city fuel economy about 15 percent lower at 20 degrees than at 77, and as much as 24 percent lower on short trips of three to four miles. Hybrids typically lose 30 to 34 percent. EVs lose about 39 percent of their efficiency, with range down about 41 percent.

Real-world results spread out from there. DOE’s range for gas cars in city driving is 10 to 20 percent, so if yours lands anywhere in that band, it’s behaving normally.

How long should I warm up my car? Does remote start waste gas?

About 30 seconds, then drive off gently. That’s what most manufacturers recommend, per the Department of Energy, and the engine warms up faster being driven than idling.

Remote start is idling, and idling gets zero miles per gallon. It won’t cost you much, roughly 11 to 28 cents for ten minutes, but it isn’t helping the engine either. Clearing ice and frost off the glass is the exception. Do that completely, every time.

Why does my tire pressure light come on when it’s cold?

Because the tires really are low. Pressure drops about 1 psi for every 10 degree drop in temperature, per AAA, so tires set in September are several psi down on a January morning. If the light goes off after a few miles, the tires warmed up, but AAA’s advice is that they’re still underinflated. Set them to the pressure on your driver’s door jamb, checked before you drive.

Is winter gas worse for mileage?

Slightly. The Department of Energy says winter blends can carry slightly less energy per gallon than summer fuel. The percentage that gets repeated online doesn’t trace back to any primary federal source we could find, so we won’t quote one.

The EPA’s summer fuel season ends September 15, and after that stations can sell winter blend. According to the EIA, it’s cheaper to produce, because refiners can blend in more butane, a low-cost component that summer rules limit.

Should I buy a hybrid now or wait for gas prices to come down?

Nobody can tell you where gas prices go next, including us, so we wouldn’t make the decision on a forecast. Make it on your timeline. If you were going to replace your vehicle within the next year anyway, today’s prices make the fuel math more favorable, not less. If your current car has years left in it, waiting is completely reasonable, and the tips on this page will do more for you in the meantime.

Either way, the number that decides it is what your current vehicle is worth, and that changes month to month too.

Do I have to drive a Toyota for you to service it?

No. We service Toyota and every other make in Lancaster, whether or not you bought the vehicle here. An Ohio January affects a Ford exactly the way it affects a Corolla.

Start this week

Two ways we can help, whatever you drive and wherever you bought it.

Get the car ready now

We’ll check your tire pressure for free while you wait, before the cold knocks it down. If an oil change is coming up anyway, it’s a good time to make sure the grade is right for cold starts. And if your check engine light is on, get it read now instead of guessing your way through January.

Run the hybrid math on your car

If the RAV4 numbers got your attention, start with your trade value. It’s the input that swings the answer most, and everything else is simple division.

What Toyota’s hybrids are rated, before winter takes its share

57 MPG Combined 2026 Prius 57 city / 56 hwy, FWD
51 MPG Combined 2026 Camry LE 52 city / 49 hwy, FWD
43 MPG Combined 2026 RAV4 47 city / 40 hwy, FWD
34 MPG Combined 2026 Grand Highlander Hybrid 36 city / 32 hwy, AWD

EPA-estimated 2026 model year combined city/highway ratings. RAV4 AWD LE and SE are rated 42 mpg combined (46 city / 39 highway), and Camry LE AWD is rated 50. Cold weather lowers all of these, as described above. Actual mileage varies with driving conditions, habits, maintenance and weather.
