Why They Invested $10 Million in This Device That Cuts Fuel Costs by Over 40%
(And How You Can Get One for Yourself)
11,239 Ratings
(ET, Wednesday, March 11, 2026 — It was the most-watched episode in Shark Tank history when James Peyton from UTAH won every single Shark over)
Never before has one Shark decided to invest $10 million dollars alone into ONE company on Shark Tank.
Seeing that this is quickly becoming “the greatest step forward in the automotive industry” the Shark was quick to lock in the deal of his lifetime to back this ex-nasa engineer from Texas.
James Peyton, an ex-engineer for one of America’s biggest car companies, tapped into his lifelong engineering experience to help find a real solution against the rising fuel costs at the pump.
The secret he discovered?
A tiny device that you plug it into your 12 volt cigarette lighter, and within 60 seconds it starts saving you money automatically.
It’s going viral on social media right now with thousands of people making videos that it saved them $100, $200 and even $400 a month in fuel costs.
Here’s how it works…
1. It Eliminates “Hidden Components Secretly Installed in Every Vehicle” That Are Stealing Your Gas Money
Fuel Saver uses advanced electromagnetic technology that overrides hidden components secretly installed in every vehicle built after 2001, components the oil industry has every incentive to keep hidden.
Components that deliberately waste 40% of the gas you pay for as fumes.
So you have to keep filling up.
Fuel Saver stops that waste completely, so every drop of gas you pay for actually moves your car forward instead of going straight out the exhaust as fumes.
It’s 100% legal, completely plug and play.
And people are driving for weeks on a single tank, no matter what vehicle they own.
2. It Works on Any Vehicle Made After 1996 (No Tools, No Wiring, No Mechanic)
Unlike expensive tune-ups or fuel system cleanings that require appointment scheduling and mechanic expertise, this device installs quickly.
Just plug it into your 12V socket and drive.
It works universally across cars, trucks, SUVs, and even heavy-duty vehicles, because every modern vehicle shares the same 12V electrical architecture.
3. It Pays for Itself in 2–3 Fill-Ups (Then Pure Savings Forever)
At current gas prices, most drivers save a noticeable amount per tank.
Since the device costs very little, it literally pays for itself within your first 2–3 fill-ups.
After that, every dollar saved goes back in your pocket.
Compare that to fuel additives that cost more per bottle and need constant repurchasing, or mechanic tune-ups that can cost significantly more and only last a few months.
4. It Stabilizes RPM and Boosts Engine Power Instantly
Beyond fuel savings, drivers notice immediate performance improvements.
The stabilized electrical current allows your engine’s computer to calculate perfect fuel injection timing, resulting in smoother acceleration, faster starts, and more responsive braking.
Your car will feel like it did when it was newer — because the electrical system is finally getting the clean, stable power it was designed for.
5. It Cuts Your Monthly Fuel Costs by Half
Fuel Saver sends electromagnetic waves at exactly 847.3 nanometers that override the magnetic disruptors in your car and make your engine burn 100% of your fuel instead of 60%.
Causing you to save over 40% a month in fuel costs.
No more spending $200, $300, $400 a month just to get to work and back.
No more choosing between filling your tank and paying your bills.
No more planning your week around how much gas you can afford.

Smoother acceleration, especially from a stop. My car used to hesitate when I pressed the gas from a red light. Now it feels more responsive. Not a sports car, but definitely noticeable. Less lag.

Installed it in 10 seconds just plugged it in. No tools, no opening the hood, no mechanic. Just pushed it into the cigarette lighter socket. That’s it. My wife looked at me like I was lying about being done.

My dashboard lights stopped flickering. I had an issue with voltage dips. The lights would dim when I accelerated. After plugging this in, the voltage is stable. No more flickering, no more dimming at stoplights.

I’m getting an extra few miles per gallon. I tracked my mileage for a month before and after. Not a huge jump, but noticeable. Enough that the device paid for itself in gas savings within a few weeks.

Has anyone tried this? I’m tired of watching my gas tank drain every week and feeling like I’m burning money with every mile.
Game changer! Used it on my road trip to Florida last month and my engine felt completely different. Better mileage and smoother performance! Worth every penny!
Finally stopped wasting money on fuel additives! Been using this device for 3 months and can’t believe how much I’m saving at the pump now 😍
I was skeptical about a plug-in device helping with gas mileage but decided to try because of the guarantee. After using it for 2 weeks my wife actually asked what was different — normally I’m complaining about gas prices every time we fill up! 🙌
@Jennifer check this out instead of that expensive tune-up you were talking about
Already ordered! So much more affordable than a mechanic visit and I can use it in every car
Does it take up a lot of space in the car? I’m already struggling with clutter in my center console.
Not at all! It’s basically the size of a phone charger. Just sits in your 12V socket and you forget it’s even there.
Update after 6 months: AMAZING! Used it through 15+ tanks of gas and every single one has been more efficient. Best automotive investment I’ve ever made 🙌
Ordered the 3-pack because they keep selling out. So glad I did — giving one to my husband for his work truck!
Smart move! I forgot to transfer mine during my last road trip and had to suffer through terrible mileage the whole way. Definitely getting extras this time
