My personal review of the fuel additive, sold below.

Before I just up and promote a product (especially one that could potentially damage your ability to get from A to B on the daily), I test it myself. Here are my findings.

For the purposes of copyright, trademark, and active account status, I do not name the product in this review, you can find the name in the company provided reseller website, linked below.

I can hear it now, "Wow this is a long article", well, it's a less than 10 minute read, if that's too much for you - you're not a candidate to be testing this product for yourself. Sorry, truth hurts.

The tablets, lets call them, have a few things going for them:
Made in USA, EPA registered, USLD Compliant with Federal Low Sulfur requirements,
Batch numbers, Manufacture date, Expiration date (5 years), and the price is printed on the package (so no price gouging).
They have an insurance policy to cover engine damage, and a local insurance agent said the policy looks to be legitimate.

Now on to the maybe not so great:
There's plenty of testimonies of earth-shattering results, it's hearsay, and I'm not here to support nor dispute some of those claims.
There are folks that have the testimony of no effective change in fuel mileage, that's also hearsay, and I'm not here to support nor dispute those claims either.
There's a lot of variables, and even if I keep mine to a minimum, doesn't mean that you will be able to, in your circumstances.
So, as the saying goes "Mileage may vary" - literally.
Oh, and for the record "hearsay" is not a inherently derrogatory word, being that we are amidst such an emotionally fragile societal period.

I wanted to additionally know a few things about the product, so I tested.

Is it safe sitting on your dashboard?
With no flame present, heating to 350 degrees fahrenheit, it began to offgas, at 500 degrees it began to liquify, at 896 degrees, it did not ignite.
When directly introducing open flame at room temperature, it immediately combusted and continued to burn until completely gone, leaving behind some soot/reside - which was expected as this is its concentrated form.
Yes, I would call that safe - for a purposely combustible material. But I wouldn't leave it plastic side up on the dashboard for 3 months

Does it fully dissolve left undisturbed in gasoline?
Yes, at about 75 degrees ambient temperature, after about 2 hours, the tablet dissolved completely in gasoline, leaving zero dregs or granules.

Diesel results?
I have no diesel. Of the folks I talked to, treated diesel seems to have larger improvement margins than treated gas. But you'll have to test diesel for yourself.

For ethanol fuel, did it alter the ethanol content?
No, water separation testing ethanol fuel of untreated vs treated - yielded no difference in the ethanol volume of the gasoline.

Did it introduce ethanol or the like into non-ethanol gasoline?
No, water separation testing treated non-ethanol fuel yielded no additional volume to the water added at start of test.

Couldn't I get the same results with readily available octane booster?
Perhaps, but not for the pricepoint, you'll see for yourself in the figures below. Also, there's a practiality issue with on the shelf octane booster - for daily drivers, you'd have to keep a stock (which has a storage footprint) of combustible and malodorous liquid in your vehicle, and the cheap stuff is $4/bottle/tank in my area.

Did it really clean your engine cylinders?
Had I realized that mechanic borescopes could be had for such economical prices these days, I would have done a before and after on that.. But I didn't know, and with no before images, perhaps you should do that if you want to know. And again my vehicle is not your vehicle.

How do you know it wasn't a placebo effect?
Well (sorry Honey) I conducted a blind test on my wife's vehicle. She didn't know I was also putting it in her car, and she's a consistent driver, with consistent routes. Her results were similar to mine, seen below.

Did it increase engine power?
I don't even know where a dynamometer is, nor do I have any desire to trouble a race shop with a bog standard vehicle - twice, as I would have to test untreated, then wait 2 hours, then test again. I wasn't really concerned with how much quicker my 4-banger with eco mode would jump off the line.

Does it contain MMT or manganese compounds?
No, it does not. Some newer vehicles are prohibitive of using such, and it is not in the tablet.

Do I have to make a commitment to be able to test this myself?
No, I decided to become a reseller, I will sell it to you (USA only), and I will eat some of the shipping cost. The parent company doesn't know you exist, and I don't have time to bother you.

What does it cost to try it?
$23.00
Purchase link further below. That's $20 for a 5-pack of tablets (1 per up to 20 gallon tank) and I'll eat some of the shipping cost. I will ship you your first 5-pack of tablets for just $3 shipping. I am paying USPS $10.40 for their smallest box so it gets a tracking number and goes through their feeders, then I have to pay applicable taxes and merchant processing. You do the math. If it works out well enough for you that you want to continue buying, we'll figure out an autoship quantity from me that works for you, for when you have to pay the full ride on shipping, or you may want to find out from me what it takes to become a reseller and get your own at wholesale (But you still have to try it first, so we're not even there in the conversation yet), or in-between is being a preferred customer direct from the company (again, those are details for a later time).

How do I know I am not fooling myself with my results?
Try your best to be consistent with your driving routes and habits during testing.
Before treating, with no other additives in the tank, fill your tank, reset the mpg counter, keep the receipt, and record your odometer reading. Drive till as close to empty as you are comfortable with. Fill your tank, keep the receipt, and record your odometer reading. Again, drive till nearing empty, record your odometer reading and your latest mpg counter reading. Do the math and check to see if your mpg counter matches your on-paper numbers - across the 2 tanks of fuel. If your mpg counter numbers are close to the paper numbers, you can then trust your mpg counter reading for further testing, if not - you'll need to do the rest by math on paper.
Treat your next tank of fuel and drive it till near empty, repeat this 2 more times (cleaning phase).
Treat your tank of fuel with the 4th tablet and reset the mpg counter again (or record all the numbers to be able to figure mpg at next fill up).
Treat your tank of fuel with the 5th tablet (and record all the numbers to be able to figure mpg at next fill up if not trusting the mpg counter).
At the end of the 5th treated tank, check your mpg numbers to compare these last 2 treated tanks to the untreated.
Why so detailed of a test? I fear some of the most impressive testimonies could be from people that haven't reset their mpg counter in quite some time, then they go drive all highway miles after the reset. It takes 2 tanks for many mpg counters to get accurate numbers, and if it hasn't been reset in a long time, the latest number prior to testing could be artificially low.

How do you know this isn't some pyramid scheme?
I've been in the MLM/direct-sales industry for 11 years. In the last decade, I watched 2 other "companies", whom claimed to have a product to increase gas mileage, come and go, that were proven to be the pyramid schemes I thought they were (I wanted no association with those scams that deserve a special place in hell). They never shipped a product, and people went to jail. When I was approached with this company, I went to digging, looking for any connections to any of the bad I had seen before, there are none. The people check out, and you can be a consumer without being a rep, and be a consumer without a commitment. They lead with a product which I have tested myself. Is being a rep/reseller/wholesaler for everyone? Nope. But if you just want to be my customer, and ONLY IF you see results for yourself - here we are.

Testing caveat:
I was puzzled, at the end of my 4th tablet, I saw only a 0.9 mpg change in my mileage, and I was doing all highway. I was doubtful, that could have been within a margin of variables. I did some digging. Turns out that my vehicle's anti-siphon measure is a strainer at the end of the fuel filler neck, near the top of the filled fuel level. With my treat/fill/drive-till-empty habits, the tablets were hanging out in the strainer not getting dissolved. To prove this was the culprit, before the 5th tablet, I filled my tank, drove home, topped the tank and filler neck all the way up with a gas can, and let it sit at least 2 hours, then drove. For that tank, I got a 3.2 mpg increase. Then with the 5th treated tank I got the 3.2 mpg increase again. But those were all highway miles, where most of the world operates around the AVERAGE between city and highway mileage, so I can't claim a 3.2 mpg increase, city driving is inherently, not as efficient. But I will say that even 14 years and 235,000 miles ago, this SUV never saw 25.5 mpg. The best I've ever seen out of it was 24.4 a decade ago. And yes, after 2 tanks, I can trust the mpg counter in it, even now. No, you can't over-treat for even better mileage, I tried that also after I discovered I needed to predissolve the tablets or leave the tank overfilled for a couple hours. But, and this is a big but: I know some of the people claiming wild results have vehicles with the same anti-siphon strainer in the way.. Remember how I said at the beginning I'm only here to share my personal test results? Maybe they fill near work or home and then park. Anyway, I'm not going down that bifurcated rabbit-hole. I did try wetting and surfacing the tablets in and out of gas multiple times over days to see if they would eventually dissolve faster, they didn't. Always takes about 2 hours, little longer in cold weather.

Ok, finally, let's see some numbers: as of 3/07/23

2008 Mercury Mariner 2wd V6 (rebadged ford escape) 235,000+ miles
last tune up 2 years ago
pre-treatment average mpg 22.3
treated peak mpg 26.3 (not a usable number, unless you only drive all highway all the time - but it's impressive for this old vehicle)
treated average mpg 24.4
increase in avg mpg = 2.1 mpg

2014 Toyota Rav4 2wd 4-cyl 160,000+ miles
last tune up, over 4 years ago
pre-treatment average mpg 24.4
treated average mpg 25.5 mpg
increase in avg mpg = 1.1 mpg

2003 Ford F-150XL 2wd V8 (4.6L) 350,000+ miles
last tune up 1 year ago
After treatment, gas mileage dropped significantly and stayed down.
Turns out that the truck still had the original fuel filter, and it was nearly stopped up.
Apparently, the slight difference in viscosity of the additive in the tank finished off what little flow the ancient filter had left or perhaps it was just uncanny timing (A clean filter would have gone unaffected).
Replaced fuel filter (mileage already on the rise) and re-establishing a baseline MPG, pre-additive, for the truck.
Will update after more testing.

2xxx Honda Pilot ?wd v? ???miles
no tune up due to lack of age
Will update vehicle specs once I have them.
increase in avg mpg = 0.15 mpg

With the current cost of gas, the amount of gas we burn, and the fact that I'm paying wholesale for the tablets I use, a lot of complicated maths I won't bore you with - we personally are above the break-even mark, IF we sold to no one, and I'm not hiding the fact that I'm here to make money, so it's a zero-loss for us, and I won't lose any sleep promoting it - as I'm only gaining customers whom get their own results and decide they want to continue to buy, and it's a break even for us on the first pack that I'll sell you.

So order a pack, try it. If you have great results - I'm your guy. If you have little to no improvement, it was a $23 test that failed your specific scenario. I've had much costlier dissappointments than that. I'd hope that you have great results - to help your family, to help your friends.. Together, above all, let's just keep it honest.
