Best Fuel Savers That Work – Top OBD Chip Devices & Gas Saving Products

Consumers have difficulty figuring out whether or not a fuel-saving technology will live up to its claims. Fuel-saving technologies are complicated to assess, and it is impossible to come to a definitive judgment on the worth of any product. Many factors contribute to the difficulty of determining fuel-saving technology. The technology underlying most fuel-saving gadgets is sophisticated, which leaves it vulnerable to suspicion, and many technologies fail to provide the benefits they claim. As a result, there are two outcomes. When a product fails to deliver on its promises, customers lose faith in the company that made a claim. When one gadget fails to save the stated amount of gasoline, the whole industry of fuel-saving devices is tainted.

People are skeptical of any fuel-saving gadgets, even those tried and validated in the lab and the field. In part, fake technologies might sound surprisingly similar to existing fuel-saving systems in their pseudoscience. Furthermore, the absence of moderation in the fuel-saving technology market contributes to skepticism. Marketing for fuel-saving gadgets makes bold claims about how their goods would transform the energy industry for the better by promising 300 percent fuel savings.

Some naysayers believe that all fuel-saving technologies are “malarkey,” not to mention those who make misleading promises. The “experts” who profit from “debunking” real fuel-saving gadgets are just as frequent as snake oil marketers marketing cheap and worthless equipment that does not boost fuel economy. On the other hand, Cynics and proponents of fuel-saving devices occupy opposing sides of the same spectrum when presenting their arguments.

How We Ranked The Top Fuel Saving Products

Every fuel saver promises that it will cut fuel use while increasing mileage. However, not all of them are successful in the field. Our editorial team evaluated the following factors when deciding which fuel savers were the finest and worst on the market today:

Fuel Saving Efficacy

You’re purchasing a fuel saver to save money on gas. We evaluated fuel savers primarily based on their ability to reduce fuel use. We put each fuel saver through its paces in real-world situations whenever feasible. One percent to two percent of the population lowered their gasoline use, while others cut their fuel consumption by 20 percent or 40 percent. Despite claims to the contrary, some have increased their fuel use. The efficacy of fuel conservation was the most critical rating element.

Additional Features

Additionally, since fuel savers connect to your car’s OBII port, they may access extra diagnostic information from your vehicle – such as the cause your check engine light is up. Additional Vehicle Diagnosis Info Fuel savers that supplied additional car diagnostic information were very appealing. However, this was not our key ranking consideration.

Easy Installation

Installation is simple, and you don’t need any automotive or technical knowledge to put in the fuel savers listed above. If you can connect to your charger, you should be able to install a fuel saver in your car. It’s that simple. On the other hand, some fuel savers are more straightforward to install than others, which we considered when compiling our rankings.


There is no money-back or satisfaction guarantee on all fuel-saving devices since not all of them operate for all cars and driving situations. Someone who commutes 100 miles each day through a flat, rural region may need a different gas saver than someone who commutes in a congested metropolis. We chose gasoline savers that came with money-back or satisfaction guarantees because they were more dependable. Generally speaking, if you are dissatisfied with both the fuel saver or if it does not function as claimed, you should be eligible for a refund.

Price and Value

You’re purchasing a fuel saver to save money. Therefore it shouldn’t be too expensive. Some fuel savers cost a lot of money, which means you’ll have to use the fuel saver over the years before seeing a return on your investment. You may find decent fuel savers for much less than $100. Therefore, they considered both price and value when compiling our evaluations to ensure that people got the most for their money.

Transparency and Reputation

A leading company has earned a solid reputation for honesty and transparency in certain businesses. There is no “monarch” of the fuel-saving sector in the same way as there is no “king” of the automobile industry. The result is that many smaller manufacturers are fighting for your business, which is good news for you! It’s a competitive industry, and we evaluated fuel-saving firms based on their credibility and transparency, among other factors.

No Permanent Reprogramming

There should be no permanent ECU reprogramming since all excellent fuel savers should be revocable after unplugging. While a professional may persistently reprogram your ECU to get better mileage (and save you hundreds of dollars), decent OBD2 fuel savers only modify your ECU whenever the device is first connected to your vehicle.

Realistically Advertised Benefits

Some fuel-saving firms go above and above in their marketing efforts. They say that their technology, for example, can quadruple your horsepower and torque and enable your minivan to drive up a mountain in one continuous motion. Others claim to be able to increase your fuel economy by two or three times. None of these statements can be supported by evidence. That’s why we valued fuel-saving firms that presented their advantages honestly, rather than making inflated marketing promises.

Build Quality & Design

While build, design, and quality were not the essential factors in our rankings, they were nevertheless considered. You want something visually appealing in your car – or at the very least not unattractive. The most effective fuel savers blend function and aesthetics to create a well-rounded product.

How Do Fuel Savers Work?

The term “fuel savers” has a magical ring to it. Is it possible to save money on petrol by plugging in a small device? Do fuel savers help improve gas mileage? However, you should be cautious of fuel savers who promise to increase horsepower or torque and lower fuel use by 50%.

Plugging into your OBD2 port is the most common way to use a fuel saver. Since 1996, all vehicles have had an OBD2 port as standard equipment. It’s usually hidden behind a small panel on the left side of a steering wheel on most automobiles. You should be able to view a port that resembles a computer port by peeling back or removing that panel.

This port has traditionally been used by technicians to identify car issues. Mechanics employ specialized software to figure out what’s wrong with a car. OBD2-enabled fuel-efficiency solutions have increased in popularity in recent years.

How To Use A Fuel Saver?

Using a fuel-saving device is simple. It doesn’t matter whether you’ve never worked on a vehicle before or if you’re a complete novice when it comes to automobiles.

Here’s the breakdown:

  • In the first step, you need to purchase a fuel saver. We’ve listed the best fuel savers above. These have been shown to increase your vehicle’s fuel economy or performance.
  • OBD2 Port: Every car manufactured after 1996 has an OBD2 port. In most cars, the OBD2 port is located to the left of the steering wheel.
  • Connect Your OBD2 Port to the Fuel Saver: Connect the fuel saver to the OBD2 port on your vehicle. It should be a breeze to put in.
  • The next step is to put the fuel saver in the OBD2 port and drive hundreds to 200 miles. The fuel saver monitors your driving patterns, mileage, and vehicle performance.
  • Allow your ECU to be remapped by the Fuel Saver: Numerous vital components of your car are managed by the ECU, the electronic control unit. Your fuel saver initializes your ECU after monitoring performance, much like a technician.
  • Finally, your fuel saver can help you get the most out of your vehicle while saving you money at the pump and improving performance.

Simply disconnect the fuel saver at any time to reverse these circumstances and return your car to its previous performance. When the fuel saver is unplugged, the ECU’s settings are restored to their original state.

What Do Fuel Savers Do?

Using a decent fuel saver recalibrates your vehicle’s ECU or electronic control module (ECM). Embedded in a car, the ECU is a computer that manages many of the vehicle’s most critical operations. Your car’s engine, for example, is controlled by a tiny computer that also operates the vehicle’s electrical systems.

OBD2 fuel savers modify your ECU to become more fuel-efficient when installed in your car. To do this, the fuel saver may:

  • Boost horsepower and fuel economy by reducing your vehicle’s electrical consumption when it’s in operation.
  • Acceleration and deceleration should be optimized to save gas.
  • Numerous more simple changes may result in considerable reductions in fuel use.

It doesn’t matter how many little ways the fuel saver cuts fuel usage by 1% to 2%; such savings add significant fuel efficiency. With an average fuel saver, you may save dollars a year.

Top Ways To Boost Fuel Efficiency

Many tried-and-true methods for improving your car’s fuel economy, regardless of whether you use a fuel saver. Several established ways include:

Minimize Cold Engine Running

Older automobiles benefitted from “warming up” their engines. In today’s cars, this is unnecessary. Maximize fuel economy by minimizing cold engine running. The fuel economy may be improved by just starting the engine and driving.

Maintain Speed

This recommendation should say that fast acceleration and severe braking reduce fuel economy. Studies suggest that reducing the frequency of forceful breaking and acceleration may increase fuel economy by 10% to 40%. When approaching a stop sign or stoplight, take your time getting off the brakes. Alternatively, use a route that eliminates traffic jams.

Most automobiles’ best fuel economy is at roughly 50mph. The fuel economy decreases when you speed up your driving. Maintain the speed limit, but consider slowing down to save money on gas.

Utilize Cruise Control

By avoiding sudden speed changes, cruise control may help you get better gas efficiency. Using cruise control preserves your current speed with the minimum amount of effort. Even if you’re a skilled driver, you can’t match the effectiveness of cruise control.

Avoid Rush Hour

Stop-and-go traffic is the worst kind for fuel economy and makes rush hour a nightmare.

Keep Clean

Removing unnecessary things from your car will save you roughly 1 percent in fuel consumption for every 100 pounds of added weight. Your mileage may be reduced if your vehicle is overburdened with needless goods.

Maintain Maintenance Schedule

Don’t wait until it’s time for such an oil change; do it now. Maintain your car by its scheduled service intervals. The air filter should always be kept clean. When your vehicle’s check engine light turns on, immediately take it to a mechanic. The fuel economy improves with proper maintenance.

Don’t Use the Air Conditioner

To save money on gas, you should switch off the air conditioning. Roll down the windows instead.

Tire Pressure

It’s easy to forget about tire pressure, but it’s an essential element of car maintenance. On the other hand, proper tire pressure is critical to maximizing fuel economy. The fuel economy is greatly improved by adhering to the recommended tire pressure for your specific vehicle. It is estimated that Americans lose 1.25 billion gallons of fuel each year due to under-inflated tires, which account for nearly one percent of their entire yearly usage.

Tire Alignment

Tyre pressure isn’t the only factor to consider while inspecting your vehicle’s tires. The alignment of the tires is also an important consideration. Unevenly placed tires will have a lower efficiency rating than precisely aligned tires. If you haven’t had your tire alignment checked, you should get it done by a professional. Ensure they are properly inflated and rotated to get the most out of your tires.

Fill Your Tank in Cooler Weather

Because of temperature variations, gasoline is heavier in the morning and at night, which means you receive a little more gas while filling it up during colder times. You should prevent filling up your automobile throughout the day since fuel density decreases as it becomes hotter.

How Engine Remapping Works

OBD2 fuel savers work by targeting the control unit of your engine (ECU). A technician must first remap your engine to get the most out of your fuel-saving features. Mechanics still remap engines for folks nowadays. Experts can remap your engine if you want to get the most out of your car while saving money on gas. These alterations are irreversible, but a technician can always reverse them for you. To get the car to function as near to its full potential as possible, the technician remaps the ECU. To do this, the mechanic might execute one of the following:

  • A 20 percent or more increase in horsepower and torque
  • Avoid putting artificial constraints on the performance of your car.
  • Put a stop to any limits on performance or emissions that have the potential to degrade efficiency and reduce performance.
  • Implement further modest and significant software modifications to improve overall system performance and efficiency.
  • Most engine remapping improves torque and horsepower without considerably enhancing fuel economy.

Engine remapping is just like a software upgrade for your car. It’s possible to have a technician apply this software update. A fuel saver may also use OBD2 port diagnostics to adopt proven adjustments in your vehicle’s performance.
