AR6400-G Gasoline Fuel System Cleaner - Professional Fuel System and Engine Cleaner (Treats 25 Gallons of Gasoline)

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!!!!!

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.

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.

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.

Have 80K miles on our Civic and never run a fuel additive thru it. Mileage has slowly been dropping from 40 plus MPG to 37. Ran a bottle thru the car as directed, and we are back over 40 MPG again

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!

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.

So I used the cleaner and additive for 2 weeks per the bottle reccomendstion and have ran 5 tanks of fuel total. 2 tanks with double and 3 tanks with normal amounts. I averaged 345 miles per tank and after using this product I have averaged 275 miles per tank. Went from 16mpg average to 13 mpg average. No change in driving habits and normal daily travel.
