Let’s be honest nobody likes pulling up to the pump anymore. Gas prices have been on a rollercoaster for years now, and it doesn’t look like they’re going to magically drop back to where we’d all love them to be. If you’re tired of watching your hard-earned money vanish every time you fill up the tank, you’re not alone.
The good news? You don’t have to go out and buy a brand-new electric vehicle or take on a huge car payment to start saving. Some of the most fuel-efficient vehicles on the road today can be picked up used for a fraction of their original sticker price and they’ll save you real money every single month at the pump.
We put together this list to help you figure out exactly which used cars are worth your attention if fuel economy is a top priority. We’re going to walk you through the best options across different categories from hybrids to traditional gas-powered cars so you can make the smartest decision for your budget.
Why Buying Used Makes Sense Right Now
Before we get into the list, it’s worth taking a second to talk about why used is the move.
New cars are expensive. The average new car price has been sitting well above $45,000, and even the more affordable options come with monthly payments that sting. When you buy used, you let someone else absorb the steep depreciation that happens in the first two or three years of ownership. A car that sold new for $30,000 might be sitting on a used lot for $16,000 just a few years later and it still has plenty of life left in it.
Combine a lower purchase price with genuinely excellent fuel economy, and you’re winning on two fronts: you spend less to own the car, and you spend less every time you drive it.
The Best Fuel-Efficient Used Cars Worth Buying
1. Toyota Prius (2016–2022) — The Gold Standard of Fuel Efficiency
If you want the most miles per gallon possible out of a gas-powered vehicle, the Prius is still the benchmark. It’s been that way for over two decades, and it’s not changing anytime soon.
The 2016 through 2022 model years are a sweet spot for used buyers. These generations got a full redesign in 2016, bringing updated styling and an even more efficient powertrain. You’re looking at around 52 mpg combined which is honestly remarkable for any non-electric vehicle. In real-world driving, that translates to stopping at the gas station far less often than virtually any other car you could buy.
The Prius has a rock-solid reliability reputation. Toyota’s hybrid system has been refined over decades, and these cars routinely hit 200,000 miles or more with proper maintenance. Parts are affordable and mechanics everywhere know how to work on them.
What to budget: Expect to pay $15,000–$24,000 depending on mileage and trim level.
Best for: Commuters, high-mileage drivers, anyone who wants the absolute lowest fuel cost.
2. Honda Civic (2014–2022) — Reliable, Affordable, and Genuinely Efficient
The Honda Civic doesn’t have hybrid badges, but it doesn’t need them. The regular gas-powered Civic especially the turbocharged models from 2016 onward delivers around 32–36 mpg combined, which is genuinely impressive for a non-hybrid. The 2014–2015 naturally aspirated models are slightly less sporty but still return excellent fuel economy and are priced even lower.
What makes the Civic stand out is the total package. It’s one of the most reliable cars ever made, it’s comfortable, it’s fun to drive, and used examples are plentiful. There are thousands of them on the market at any given time, which keeps prices competitive and gives you plenty of options.
Insurance rates on the Civic are typically lower than average, maintenance costs are low, and mechanics everywhere are familiar with the car. It’s about as low risk a used car purchase as you can make.
What to budget: $13,000–$22,000 depending on year, trim, and mileage.
Best for: People who want a practical, efficient, no-fuss daily driver at a reasonable price.
3. Toyota Camry Hybrid (2018–2022) — Efficiency Without Sacrificing Comfort
If you want something larger and more comfortable than a compact car, the Camry Hybrid is one of the best values in the used market. These cars return around 46–52 mpg combined, which is extraordinary for a midsize sedan. You get a genuinely spacious interior, a comfortable ride, and Toyota’s legendary hybrid reliability all in a package that doesn’t scream “economy car.”
The Camry Hybrid is especially well-suited for families or anyone who does a lot of highway driving. It’s smooth, quiet, and capable on long trips while still saving you serious money at the pump compared to a traditional sedan.
Used examples from 2018 onward are a particularly good deal right now, as the market has softened somewhat on these compared to peak used-car pricing from a couple of years ago.
What to budget: $22,000–$32,000 for well-maintained examples.
Best for: Families, commuters who need more space, drivers who want hybrid efficiency in a comfortable package.
4. Honda Insight (2019–2022) — The Underrated Hybrid Worth a Second Look
Here’s one that doesn’t get enough attention: the Honda Insight. Honda relaunched this hybrid nameplate in 2019 after a long hiatus, and it quietly became one of the most fuel-efficient non-Prius sedans on the market, achieving around 52 mpg combined.
The Insight looks like a regular Civic understated, clean, nothing flashy but underneath it’s running Honda’s two-motor hybrid system that delivers exceptional real-world fuel economy. It’s comfortable, well-equipped, and because it doesn’t have the Prius name recognition, used prices are often lower than you’d expect for a car this efficient.
If you can find a clean one in your area, it’s worth considering. These are reliable cars from a brand with a strong track record in hybrid technology.
What to budget: $18,000–$26,000 for 2019–2022 examples.
Best for: Hybrid shoppers who want Prius-level efficiency at potentially lower cost.
5. Hyundai Ioniq Hybrid (2017–2022) — Exceptional Fuel Economy at a Lower Price Point
Hyundai has been making serious strides in fuel efficiency over the past decade, and the Ioniq Hybrid is proof of that. The standard hybrid version returns around 58 mpg combined yes, you read that right. It’s one of the highest-rated non-plug-in hybrids you can find, besting even the Prius on paper.
Used Ioniq Hybrids are typically priced below Toyota and Honda competitors, which makes them an attractive option if you’re working with a tighter budget. Hyundai has significantly improved its reliability reputation in recent years, and these cars come backed by the original manufacturer’s warranty if you find a low-mileage certified pre-owned example.
The interior is on the smaller side and the ride isn’t quite as polished as a Prius or Insight, but for raw mpg per dollar spent, it’s hard to beat.
What to budget: $14,000–$21,000 depending on year and mileage.
Best for: Budget-conscious shoppers who prioritize maximum fuel economy above all else.
6. Mazda3 (2019–2022) — When You Want Efficiency AND Driving Pleasure
Not everyone wants to drive an appliance. If you care about how a car actually feels behind the wheel, the Mazda3 is the fuel-efficient used car for you.
The 2019-and-newer Mazda3 with the 2.5L Skyactiv engine returns around 30–35 mpg combined and feels substantially more engaging and premium than you’d expect at this price point. Mazda has invested heavily in making their cars feel closer to luxury vehicles, and it shows in the interior quality, ride quality, and handling.
It won’t blow the Prius out of the water on mpg, but if you dread the idea of driving a boring economy car every day, the Mazda3 strikes a genuinely satisfying balance between efficiency and enjoyment.
What to budget: $18,000–$27,000 for 2019–2022 examples in good condition.
Best for: Drivers who want solid efficiency but refuse to give up driving enjoyment.
7. Toyota Corolla Hybrid (2020–2022) — Compact Efficiency, Toyota Reliability
Toyota added a hybrid version of the Corolla in 2020, and it quickly became one of the most sensible compact cars on the market. With fuel economy around 52 mpg combined in a package smaller and slightly more affordable than the Camry Hybrid, it fills a nice gap in the lineup.
The Corolla Hybrid drives well, feels solid, and benefits from Toyota’s proven hybrid system. It doesn’t draw much attention to itself it just does its job quietly and efficiently. If you’ve always trusted Toyota and want a smaller hybrid than a Prius or Camry, this is exactly what you’re looking for.
What to budget: $22,000–$28,000 for 2020–2022 examples.
Best for: Compact car buyers who want Toyota reliability with genuine hybrid efficiency.
Tips for Buying a Used Fuel-Efficient Car
Finding the right car is only half the battle. Here are a few things to keep in mind when you’re actually shopping:
Get a pre-purchase inspection. Before you hand over any money, have an independent mechanic inspect the car. This is especially important with hybrids battery health matters a lot, and a failing hybrid battery can be an expensive repair.
Check the vehicle history report. A Carfax or AutoCheck report will show you accident history, ownership records, and whether the odometer readings are consistent. Don’t skip this step.
Research insurance costs before you buy. Some vehicles cost more to insure than others. Get a quote before you commit so there are no surprises.
Consider certified pre-owned (CPO) programs. Toyota and Honda both run strong CPO programs that include inspections and extended warranty coverage. For a hybrid, that peace of mind can be worth paying a small premium.
Think about your driving habits. Hybrids shine most in city driving, where the regenerative braking system recaptures energy that would otherwise be lost. If you primarily drive on the highway, a highly refined conventional gas car like the Civic might actually suit you just as well.
The Bottom Line
Rising gas prices are frustrating, but they don’t have to define your budget. A smart used car purchase can cut what you spend on fuel dramatically and in many cases, you can find a reliable, well-equipped vehicle for significantly less than you’d pay for a new economy car.
Whether you go with the unbeatable efficiency of a Prius, the everyday practicality of a Honda Civic, or the surprising bang-for-buck of a Hyundai Ioniq Hybrid, you’ll be making a decision your wallet will thank you for every time you drive past the gas station with a full tank.
Do your research, get an inspection, and don’t rush. The right car is out there and it’s going to save you money for years to come.
