Why you should generally avoid any OBD2 device, especially if it’s green and white, that promises enormous fuel savings.

If you’re reading this blog post, chances are you saw that ridiculous YouTube video of a convincing looking older guy with a beard and hat in front of a truck telling you about a “fuel saving device” that his friend “found online” that he plugs into his car that gets him “almost twice as many miles per gallon than before.”

Here’s that exact video.

The man told you to click the link in the description so you can grab one of these fuel saving devices while supplies last.

You were then forwarded to a wesbite called SectorInsider.com with a CNN logo which then forwarded you to shop.buyoptifuel.com where, for as little as $40 (if you buy three,) you can get one of these OBD2 Fuel savers for yourself.

Before you click over to OptiFuel Saver’s website and click “Complete My Order,” here’s why you should stop, consider some of these red flags, and should probably not buy the OptiFuel Fuel Saver.

Read the rest of this blog post before buying the OptiFuel Saver

Red Flag #1- Sites like SectorInsider.com and BuyOptifuel.com are newly registered, less than a year old.

First, you should know that the official looking article with the CNN Logo is, in fact, not a CNN article.

Here is the domain information for sectorinsider.com, as you can see, it’s been created and registered in February, 2022, this site is only a few months old.

Then, there’s BuyOptiFuel.com, that site’s less than a year old, too, created and registered in December, 2021.

Here’s their domain information.

As you can see, these are newly registered sites and presumably, newly registered “companies” with no prior history (that I can find.)

This is a characteristic of so-called “fly by night” companies that are made solely to sell you a product that is taking advantage of a situation (high gas prices in the news,) the product never delivering on its claims.

This is a BIG red flag.

Red Flag #2 – Youtube comments on the video are all suspiciously positive, almost like the video uploader is not allowing any negative replies whatsoever.

Here’s a screenshot of the comments on that video “praising” this fuel saver.

These comments? All probably fake.

I invite you to click on any of the commenters profiles, more often than not, their profiles are empty with few active subscriptions.

It looks like compromised accounts or so-called “fake” Youtube accounts taken over by someone else are the only ones commenting on this video.

Based on that alone, I would not trust any comments on that video.

It looks like all the comments on their video are fake.

Red Flag #3- The “review” of the OptiFuel Saver on MarylandReporter.com is sponsored content.

Look up reviews for the OptiFuel Saver on Google and one of the top results is from a site called MarylandReporter.com, link to the article here.

In fact, Maryland Reporter is a real site with actual news written by local journalists and hired writers.

But, keen eyes will notice that this “review” for the OptiFuel Saver is Sponsored Content.

Maryland Reporter presumably will accept any type of sponsored content written by a company for their product for a fee. A scroll through of their list of sponsored content reveals dozens of products with “biased” reviews.

A read through of their advertising rates reveals Maryland Reporter will probably post anything for whatever they charge.

And, as long as it’s labeled “sponsored content” they’re aren’t inherently doing anything wrong.

Just be aware that someone paid to post these words about the OptiFuel Saver and it’s a review that I wouldn’t trust as real.

Redflag #4- How OptiFuel Saver is a lot like other OBD2 fuel savers sold on the internet.

So far, I’ve written about four other OBD2 fuel savers that all claim to do a similar thing as the OptiFuel Saver, that is increase MPGs, boost engine performance, and help save the environment while you’re doing it. (list of fuel savers reviewed linked here.)

Just like those other OBD2 fuel savers, I’ve revealed how, if you search for “OBD2 fuel savers” on a Chinese Wholesale site like Alibaba.com or Wish.com (try clicking on this one) you’ll see they sell green and white OBD2 fuel savers that look just like this OptiFuel Saver.


You can buy these green and white OBD2 fuel savers without a logo for as little as $3 a piece.

Here’s what it looks like is going on, Optifuel Saver is probably the exact same OBD2 fuel saver as those wholesale ones, but, OptiFuel has printed their own logo, slapped it onto these generic ones, and are selling them to you for more than 10x the price.

And, as I’ve already blogged on those other OBD2 fuel savers, these OptiFuel Savers cannot and do not back up any of their claims with hard data or test results.

It’s almost like they can’t because the product doesn’t actually work.

All these green and white OBD2 fuel savers do is play a programmed sequence of flashing LED lights that convinces you it’s working.

And, when the devices are taken apart, they’re almost always the same, there’s a convincing looking motherboard and chipset.

But, when people with actual electronics backgrounds actually “read” what’s going on with these chipsets, they almost all invariably conclude there’s no way for any of these OBD2 fuel savings devices to communicate with your car’s computer in any meaningful way that will reduce fuel used or increase engine performance.


Based on all those red flags and from what I’ve blogged about before, it’s clear what the OptiFuel Saver is.

There’s a reason you came across that video, someone is trying to convince you the OptiFuel Saver OBD2 device works.

They use a convincing, trustworthy looking older guy in their video, fill their Youtube video with fake comments, forward you to a site that looks like CNN, and planted a sponsored piece of content from the Maryland Reporter when you inevitably Google for reviews.

They’re also taking advantage of this particularly vulnerable time when gas prices are exceptionally high.

It’s all a ruse!

So please, save your money.

My opinion? Don’t buy an OptiFuel Saver, it’s probably a scam.


  1. open it & observe the circuit board, it only operates the LED light sequence & not powerful enough or actually soldered to processor that would be connected to the CAN through OBD11 plug so impossible to do anything other than draw power to operate 3kb processor for LED sequence.

  2. Their product is useless, and their use of the trade name OptiFuel for their product infringes on the OptiFuel trademark owned by the company I work for.
