AR6400-G Gasoline Fuel System Cleaner

I bought four bottles of this product for my gasoline vehicles. One for my wife’s 2021 Range Rover, one for 2023 bronco, one for my 2025 Alpha Romeo Plano increased range on the Range Rover was about 80 miles from a normal gas and raised our miles per gallon by about 35%. I increased my distance to empty from 265 to 364 on my Alpha Romeo Plano my miles per gallon average went up 40% on our four-cylinder bronco with 37 inches tires and a 4 inch lift. The product is truly amazing!!

Use every 5000 miles. No engine problems over 300,000 miles in 2001 Corolla.

I've been using Archoil since the original appearance on JLG on both my diesel and gas engines. But I must say I'm bummed they dropped all the other fine products they offered! Gun oil, lube grease....
BIG MISTAKE!!!! YOUR PRODUCTS WERE THE VERY BEST ON THE MARKET!!! AND YES I'M YELLING!!!!

Put this in my 2016 Jeep, that has been upgraded. After using this, I noticed my throttle response was more sensitive as the injectors and fuel system has been cleaned out, it brought back the power I lost over the years. Very impressive.

Use it every 5000 miles, keeps all 7 of my cars and truck running great.

My 2005 Silverado had spark knock from almost the day I brought it home. I only drive 12 miles daily back and forth to work. After using the AR6400-G for less than a month, NO more spark knock. Quality products that deliver results. Thanks Archoil.

I have been using Archoil products for around the last 7 years. I first started with the AR9100 and AR6200 in my 05 F350 6.0. Made me a believer after my 1st oil change. The sound of my engine changed, idle smoothed out immediately. Had a slight stiction issue- gone. Used the AR6400D and my truck runs like new. I also use the AR9100 in my heavily modified 87 ThunderBird 5.0 Turbo Coupe. I use the AR9100 every oil change in my truck and car. I will be using it in my 2019 Genesis G80 5.0 as soon as it has enough millage for an oil change.

I have noticed no difference after using one bottle. Hopefully after my second of use I will see better MPG.

I've been using the diesel equivalent so I tried the gas version. Had a long trip planned so I thought it was a good opportunity I think the truck ran better and got better mileage. . the only downside was that I was expecting it to be a thin as the everyday fuel treatment. It's quite a bit thicker and didn't empty out of the container quickly. I pulled it out of the filler pipe too soon as made a big mess on the side of the truck and on the ground. Next time I'll know better.

I have a new outboard on my pontoon boat that, despite proper winter storage measures, the dealer said had injectors gummed to the point of needing disassembly mechanical cleaning.. It would barely idle. Probably bad gas. I learned of Archoil's AR-6400-G. Ran some through and the difference was amazing! Runs well enough to trust it on the lake. Gonna treat a full tank now with another bottle and we should be good to go. Archoil is my new and onlyfuel additive from now on.

I used your Diesel fuel system cleaner in our 2007 Ram 5.9 Cummins and was amazed at the results. The fuel mileage went from roughly 14-15 mpg to 20-22 mpg avg. I have been following up with the fuel treatment and the truck seems to be much smoother with better throttle response as well. The truck has 265k on the engine and has not had any treatment that has been this effective. Thanks!

Part of normal maintenance. I use Archoil for my diesel truck and now I'm trying it for my gas car. I'm trying different brands to confirm quality. It would be nice if Archoil was a bit clearer on the ingredients, specifically the amount of PEA they are using.

My 2020 Ram 3500 EGR Valve was clogged. The truck was in leap mode.
After pouring a bottle in and letting it work. It increased my fuel mileage and horsepower.

Used to use Archoil in my Ford diesel and had great results. Tried the gas version in my two Toyotas and seems to help my gas mileage and helped to improve idle a little at least to my ear.

Have used this in all my gas engine cars an am very impressed as the how all have improved on performance. Great product and will highly recommend to anyone!!!!!

Been using fuel system cleaner since I bought my truck new. Between using this and your oil friction modifier I have never had a problem in 134,000 miles.

Given that US gasoline is of the poorest/cheapest quality (Thanks energy corporations) using an additive is imperative. Independent tests keep coming up with similar results, and Archoil always ranks highly! I believe it's a good investment and I want my (expensive) engine in top condition.

This product worked as advertised. Is a great product.

Great product i put this in all my small engines notice improvement with in half tank used but f’ing expensive to use as recommended
PS Archoil Lower the price and more will buy instead of a few at higher price !

Use it in my wife's Taurus and it helps keep injectors clean, efficient , and running well. Thanks

Used the recommended dosage in my 1959 Ford tractor before a long day of heavy and thick brush cutting. Tractor ran smoothly, idled smoothly, cranked and started right up with no issues. Will use next in my 1978 Ford F250 with a 460 engine.

I had lots of trouble with my 5th gen RAM’s DPF, replaced and retuned worked but using Archoil AR6400-G and AR6200 decreased use of DEF, Regena, and actually increased mileage by 1-2 mpg pulling a loaded 30’ camping trailer. Put 2500 miles on the truck and I am very impressed.

I had great success with the diesel treatment,so I tried this on my wife's hummer h2,has a loopie idle,and code for random misfire .it's in storage,so did not drive it yet,but seems better on a long idle.

Increased my gas mileage from 17-21

Used fuel system cleaner and fuel treatment as directed actually lost around 2mpg. Not impressed. I have used diesel fuel treatment with success.

Favorite son in law had emissions light go on. Used full bottle and full tank of petrol on a non stop 300 mile trip. Light went off. No issues since. I use half bottle in my wife's infinity and other half on my 2005 Sierra with 83K miles once a year. Wish it wasn't expensive.

I own a 2015 BMW 550i twin turbo and a 2017 GMC Canyon CREW CAB SLE. I purchased a kit for both vehicles and I’m impressed with the results. I’ve noticed an increase on power with acceleration and increase in mileage per gallon. I honestly can’t give an actual number of additional mileage but recently I thought the Canyon’s gas gauge was broken due to moving slower than usual after driving to distance locations driven before. This all happened while adding the recommended amount of gas-tank additive per thankful. At this point in time I don’t know how if any truth to cleaning my fuel injectors since I haven’t serviced them. I guess that is a good thing…..hope this helps! God Bless!
