How We Ranked

Every fuel saver claims to reduce fuel consumption and boost mileage. However, not all of them perform well in the field.

To separate the best and worst fuel savers available today, our editorial team considered the following:

Fuel Saving Effectiveness: You’re buying a fuel saver to save fuel. We primarily judged fuel savers based on their fuel saving effectiveness. We tested each fuel saver in real world conditions wherever possible. Some reduced fuel consumption 1% to 2%, while others reduced fuel consumption as much as 20% or 40%. Some increased fuel consumption despite claiming to save it. The primary ranking factor was fuel saving effectiveness.

Additional Vehicle Diagnosis Information: Because fuel savers plug into your vehicle’s OBII port, they can draw additional information from your vehicle – like the reason your check engine light is on. We liked fuel savers that provided additional vehicle diagnosis information, although it was not our primary ranking factor.

Ease of Installation: You don’t need any automotive skills or mechanical experience to install the fuel savers above. If you can plug in your phone charger, then you can install a fuel saver on your vehicle. It’s that easy. However, some fuel savers are easier to install than others, and we considered ease of installation in our rankings.

Moneyback or Satisfaction Guarantee: Not all fuel savers work for all vehicles and driving conditions. Someone who drives 100 miles across a flat, rural area every day might need a different fuel saver than someone driving across a crowded city. That’s why we liked fuel savers with moneyback or satisfaction guarantees. If you’re not satisfied with the fuel saver, or if it doesn’t work as advertised, you should be able to obtain a refund.

Price & Value: You’re buying a fuel saver to save money, so it shouldn’t cost a fortune. Some fuel savers cost hundreds of dollars, which means you need to drive with the fuel saver for years before breaking even. You can find good fuel savers for less than $100, and we considered price and value in our rankings to ensure users were getting the best bang for their buck.

Manufacturer Reputation & Transparency: With some industries, there’s a clear industry leader. With the fuel saver industry, there’s no single company that’s “king” of the space. That means there are many smaller manufacturers competing for your business. It’s a competitive environment, and we assessed fuel saver companies based on their reputation and transparency.

No Permanent ECU Reprogramming: All good fuel savers should be reversible after unplugging them. While a mechanic can permanently reprogram your ECU for better mileage (and hundreds of dollars), good OBD2 fuel savers only reprogram your ECU when the device is installed.

Realistic Advertised Benefits: Some fuel saver companies go above and beyond with their marketing. They claim their device can double your horsepower and torque, for example, and allow your minivan to drive straight up a mountain. Others claim to double or triple your fuel efficiency. None of these claims are realistic. That’s why we appreciated fuel saver companies with honest advertised benefits – not exaggerated marketing claims.

Build Quality & Design: Build quality and design wasn’t the most important factor in our rankings, but it was a factor. You want something to look good in your vehicle – or at least not ugly. The best fuel savers combine function and form for an effective overall product.

How Do Fuel Savers Work?

Fuel savers sound magic. Can you really save money on gas by plugging a small device into your vehicle?

Yes, fuel savers can genuinely increase fuel efficiency. However, you should be skeptical of fuel savers that claim to boost horsepower or torque or reduce fuel consumption by 50% or more.

Most fuel savers work by plugging into your device’s OBD2 port. Every vehicle made after 1996 has an OBD2 port. On most vehicles, it’s behind a small panel to the left of the steering wheel. Just peel back that panel or remove it, and you should see a port that looks like a computer port.

Traditionally, mechanics use this port to diagnose vehicle problems. Mechanics use special software to analyze vehicle problems and determine what’s wrong.

In recent years, however, we’ve seen a surge in the number of fuel efficiency products that use your OBD2 connector.

How to Use a Fuel Saver

Using a fuel saver is straightforward. All fuel savers are designed to work even if you have zero car repair experience, automotive skills, or technical skills whatsoever.

In fact, as long as you can plug your charger into your phone every night, you should have no trouble using a fuel saver.

Here’s how it works:

Step 1) Buy a Fuel Saver: Buy any of the top-ranked fuel savers on our list above. All of them are proven to boost fuel efficiency or performance (or both) on your vehicle.

Step 2) Find your Vehicle’s OBD2 Port: Every vehicle made after 1996 has an OBD2 port. Your OBD2 port is to the left of your steering wheel in most vehicles.

Step 3) Plug the Fuel Saver Into your OBD2 Port: Insert the fuel saver into your OBD2 port. It should slide in without issue.

Step 4) Drive 100 to 200 Miles: Next, drive 100 to 200 miles with the fuel saver in your OBD2 port. The fuel saver tracks your driving habits, mileage, and vehicle performance.

Step 5) Let the Fuel Saver Remap your ECU: Your vehicle’s electronic control unit (ECU) controls various crucial components across your vehicle. After analyzing performance, your fuel saver remaps your ECU – just like a mechanic would remap your ECU.

Step 6) Enjoy Better Fuel Efficiency and Performance: Your fuel saver will boost fuel efficiency and performance, helping you optimize performance and reduce spending at the pump, among other benefits.

To reverse these conditions at any time and restore your vehicle’s original performance, just unplug the fuel saver. Unplugging the fuel saver immediately removes all changes made to the ECU.

What Do Fuel Savers Do?

A good fuel saver reprograms your vehicle’s electronic control unit (ECU), also known as the electronic control module (ECM).

The ECU is an embedded system in a vehicle that controls crucial functions of the vehicle. It’s a small computer that controls the engine and other components, for example, along with electrical systems in your vehicle.

When you install an OBD2 fuel saver into your vehicle, the device reprograms your ECU to be more fuel-efficient. To do that, the fuel saver might:

  • Reduce electrical consumption by your vehicle during use, helping you maximize horsepower and fuel efficiency
  • Optimize fuel consumption during acceleration and deceleration to reduce gas usage
  • Boost fuel efficiency in dozens of other small ways, all of which add up to significant fuel savings

Even if the fuel saver reduces fuel consumption by 1% to 2% in a dozen small ways, those savings add up to significant fuel efficiency. You could save hundreds of dollars at the pump each year with an average fuel saver.

How Much Fuel Can You Save?

An average fuel saver claims to boost fuel efficiency by 10% to 20%. However, some claim to save you as little as 2% to 5% (which is realistic), while others claim to save you as much as 40% to 50% (which is not realistic).

In reality, fuel efficiency varies widely based on your driving habits, driving conditions, vehicle type, and other factors.

Some drivers will save hundreds of dollars by installing a fuel saver in their vehicle. Others will save only a few dollars.

Someone who drives significant miles in an old, inefficient vehicle, for example, will save more money than someone who drives a new, optimized vehicle.

Top 11 Best Ways to Boost Fuel Efficiency

Whether you use a fuel saver or not, there are certain proven ways to boost fuel efficiency.

Some of the best and most proven ways to boost gas mileage include:

Minimize Cold Engine Operation: Older vehicles benefited from “warming up”. This isn’t necessary in modern vehicles. Minimize cold engine operation to maximize fuel efficiency. Start the engine and drive the car normally to maximize fuel efficiency.

Avoid Rapid Acceleration and Hard Braking: This tip is obvious: rapid acceleration and hard braking is bad for fuel efficiency. In fact, studies show you can improve fuel efficiency 10% to 40% by minimizing hard stopping and acceleration habits. Avoid accelerating quickly off a stop sign or stoplight. Or, pick a route that avoids stop-and-go traffic.

Observe Speed Limits: Most cars have maximum fuel efficiency at around 50mph. As you drive faster, fuel efficiency drops. Observe speed limits, but consider adjusting speed to maximize fuel efficiency.

Use Cruise Control: Cruise control is a good way to improve gas mileage because you avoid fluctuations. Cruise control uses the optimum amount of power necessary to maintain your current speed. You may be a good driver, but you’re not as good as cruise control for efficiency.

Avoid Rush Hour: Rush hour is the worst for fuel efficiency because you’re driving in stop and go traffic, which is the worst possible traffic for fuel efficiency.

Remove Unnecessary Items from your Vehicle: Each 100lbs of weight you add to your vehicle reduces fuel economy by around 1%. If you have unnecessary items in your vehicle weighing you down, then it could reduce your mileage.

Practice Good Maintenance Habits: Change your oil when it’s time for an oil change. Follow your vehicle’s recommended maintenance schedule. Make sure the air filter is clean. Visit an auto repair shop to service your vehicle as soon as the check engine light comes on. Good maintenance leads to good fuel efficiency.

Turn Off the Air Conditioning: If you’re serious about fuel efficiency, then you’ll want to turn off the air conditioning. Instead of using the air, roll down your windows.

Maintain Optimal Tire Pressure: Tire pressure is an easy-to-overlook part of vehicle maintenance. However, good tire pressure is crucial for fuel efficiency. Follow your vehicle’s optimal tire pressure guide for the best possible fuel efficiency. According to the United States Department of Energy, Americans waste 1.25 billion gallons of gasoline – approximately 1% of total annual consumption – on under-inflated tires each year.

Check Tire Alignment: It’s not just about tire pressure. It’s also about tire alignment. Tires that are poorly aligned will be less efficient than tires that are perfectly aligned. If you haven’t checked your tire alignment, then get the professionals to check the alignment. You should also balance and rotate your tires for optimal efficiency.

Fill Your Gas Tank Early in the Morning or Late at Night: Here’s a sneaky trick gas stations hate: fuel is denser in the morning and night because of temperature changes, which means you get slightly more gas when you fill up at cooler times of day. Fuel is less dense as it heats up, so you should avoid filling up your car in the middle of the day.

What is the Electronic Control Unit (ECU)?

Your vehicle’s electronic control unit (ECU), also known as the electronic control module (ECM), is the electronic hub of your vehicle. It’s like a small computer that controls your vehicle and its components.

Your ECU controls more than just your vehicle’s electronic systems. It also controls your engine and other crucial components.

Modern vehicles have many ECUs, including:

  • Engine control module (ECM)
  • Powertrain control module (PCM)
  • Transmission control module (TCM)
  • Brake control module (BCM or EBCM)
  • Central control module (CCM)
  • Other computers, including the body control module (BCM) and suspension control module (SCM)

Technicians often refer to these systems collectively as your “car’s computer.” Technically, however, they’re several separate computers.

When you plug a fuel saver into your vehicle’s OBD2 port, it interacts with your ECU or ECM, which could impact multiple computers on your vehicle. A good fuel saver will try to remap vehicle performance, adjusting your vehicle’s settings in small ways to boost fuel efficiency.

Fuel Savers Work Better on Older Vehicles Than Newer Vehicles

Newer vehicles are designed to be as fuel efficient as possible. Older vehicles may have been fuel efficient upon release, but they’ve become less efficient over time.

You may experience more benefits by installing a fuel saver into an older vehicle than a newer vehicle. There’s more room to save fuel than you would get with a newer vehicle.

However, that doesn’t mean fuel savers are useless on newer vehicles. Fuel savers can deliver crucial insight into your vehicle and its performance, including the reason you’re getting a “check engine” light.

How Engine Remapping Works

A good OBD2 fuel saver remaps your engine by targeting your engine control unit (ECU).

Before fuel savers are launched, a mechanic needs to remap your engine to improve performance. Today, some people still get mechanics to remap their engines.

When mechanics remap your engine, they analyze vehicle performance and adjust it in small or large ways to maximize fuel efficiency. You cannot reverse these changes on your own, although a mechanic can reverse these changes at any time.

During a remap, the mechanic changes the ECU software to help the vehicle perform as close as possible to its maximum capabilities. To do that, the mechanic could:

  • Increase horsepower and torque by 20% or more
  • Avoid artificially restricted limits on vehicle performance
  • Limit performance or emissions restrictions that impact performance and fuel efficiency
  • Implement other minor and major software changes to boost efficiency, performance, or both
  • Generally, engine remapping boosts torque and horsepower without significantly boosting fuel efficiency.

Overall, engine remapping is like a software update for your vehicle. A mechanic can install that software update for you. Or, a fuel saver could analyze your vehicle needs from your OBD2 port, implementing proven changes to boost vehicle performance.

Do Fuel Savers Make Permanent Changes?

Fuel savers do not make permanent changes to your vehicle.

In fact, you can reverse all fuel saver changes just by unplugging the device from your OBD2 port.

After removing your fuel saver, your car’s central computer (ECU) will revert to its original form. It will not save any changes that are implemented.

This is different from engine remapping by a mechanic: when a mechanic remaps your engine, the changes can only be reversed by another mechanic remapping the engine.
