There can be nothing more thrilling than a road trip — heading out on the highway, looking for adventure — then what comes your way is the less-exciting prospect of paying for gas. With soaring gas and fuel costs, driving down the block is almost as daunting as farther destinations.

There are many companies developing technology designed to help with fuel costs and emissions, but what they are designed to do and what they actually do may be two different things. 

What Is MileMax Fuel Saver?

MileMax Fuel Saver is a device focused on fuel economy. Essentially, it is a fuel-saving device that you can — theoretically — put in your car to increase your gas mileage by improving fuel efficiency and reducing fuel consumption.

Optimizing fuel efficiency and reducing emissions sounds like a winning proposition, but the question remains: Does MileMax Fuel Saver work?

How MileMax Fuel Saver Claims To Work

According to the official website, MileMax Fuel Saver works in the following plug-and-play ways:

  1. Connects to the OBD-II port in your vehicle
  2. Uses AI technology to optimize fuel performance and save fuel
  3. Reduces fuel consumption by up to 35%
  4. Adapts to your driving style and your car’s performance after driving approximately 150 miles 
  5. Designed to interface directly with your engine control unit
  6. Improves performance settings, such as injection timing and boost pressure

MileMax Fuel: Scam or Real?

All of these qualities and features this device claims to have sound ideal, yet there is little evidence supporting that MileMax Fuel Saver actually saves fuel. You can see why this could be problematic.

Some red flags include: 

  • The website posts no physical address or phone number for the company.
  • Even if the device does make your car more fuel efficient, a 35% reduction in fuel consumption is unsupported.
  • The website’s domain owner’s contact information is hidden. 

The site also displays certain tactics to urge you to buy quickly without thinking too much about it, such as claiming limited availability and showing a pop-up box reporting that someone “just purchased” a MileMax device. While these tactics are not exclusively used by scams, urgency is commonly employed by scammers.

Pros and Cons of MileMax Fuel Saver

There are many benefits to having a fuel-saving device installed in your vehicle — if it works — and potential drawbacks if the device itself doesn’t work.

Before purchasing any fuel-saving device, be sure to research both the company and consumer product reviews. Embellishing what a product can do is bad enough, but if a device is found to be fraudulent in its claims, the results can be much more serious.
