Archoil at Jay Leno's Big Dog Garage: Formula Atlantic Race Car

Definitely does what its supposed to do!!!. Noticed a huge difference in how my 6.0 run and drives. Was shocked on how quickly it works, and how much quiter it is plus so much more responsise. Definitely will be running this stuff for life. Highly recommend. Will be buying another kit for my 7.3

2012 F350 CC dually with 6.7 powewrstroke and 181,000 miles. Mileage went from 14.8 to 16.2 combined mpg, regen frequency is way down, and I had no idea how much power I had lost over time. This is one of the few products that does what it says it will do!

I recently bought a 2015 F250 with the 6.7. It has a 110,000 miles on it and checked out fine with my mechanic. I was getting 14 mpg’s combined highway and city. After using these products my mpg increased to 16 and I noticed an increase in pickup power. I haven’t towed with it yet because it’s the dead of winter and I’ve nowhere to boat lol! I would recommend!

My experience on both gasoline and diesel (2016 MY MB Sprinter) is that the improved mileage (ca 1mpg+) helps pay for keeping injectors and engine in good condion as evidenced by smooth and reliable performance on high mileage vehicles.

It works! Last oil change I flushed my HPOP reservoir with Seafoam, then added half & half synthetic Rotella (hard to find right now) and ArchOil to the reservoir. The engine now runs smoother, quieter and starts with ease. Hopefully this will preserve the injectors until the top-end O-rings (all of them, HPOP to the pedestal) need to be replaced. I'm convinced that Archoil not only works but will help prolong the life of the engine.

Not sure how you managed to put magic in a bottle, but this worked wonders for me. My 2007.5 Silverado 2500HD (Duramax LMM) with 180K+ miles was going into regen every 200 miles or so and thus oil changes were DIC suggested at about 2000 miles. Based on reviews I bought a bottle of AR6400-D during a recent sale ; no harm in trying, right? Used the recommended dosage and the soot level immediately started decreasing (I monitor many parameters using and Edge CTS2). Went through a regen during this treatment and saw the soot level go to 0 and stay there for quite a while. Regens are now up to 350-400 miles and oil change recommendation at almost double the previous interval. Cannot give hard data, but my turbo seems to spool quicker now. And like others, my fuel economy has increased measurably. My injector balance numbers were very good before using this and of course remain so. I will be using this at every oil change.

I always used hot shot secrets stiction eliminator on my 6.0 powerstroke but one day the stiction started up again and hot shot secret wasn’t cutting it anymore, a friend of mine recommended archoil to me and he preached about it all the time that it was best stuff in the world, so I gave it a shot and ordered me some and when it arrived changed the oil and added archoil and the archoil fuel additive as well drove the truck for around town doing some errands and the next morning on a cold start it started up and drove well with no hesitation on takeoffs, I was amazed by the product, I would definitely use from now on, highly recommend these products!!! Five star and thumbs up for me!!!

I first started using AR6500 after my son and I rebuilt a Ford 350 6.0. My son had ran across the feedback for the AR6500 and because of the great reviews, we wanted to give it a shot. The results in our 6.0 were FANTASTIC. You could hear the difference in the engine immediately. There was no delay. Having to check the egr regularly, we began seeing next to no build up on the egr. The engine sounded better, accelerated better. You could feel the difference when you drove it compared to before its use. Great product. I make sure I have enough for every oil change, every tank of diesel and every 3-5000 miles. We really use our 6.0 hauling, working, and towing. I can't say enough good about it. Shoot we have even added the fuel addictive to our riding lawn mowers and push mowers, which are gas, and they all run waaay better. If you haven't tried this product for your diesel, you have to buy you some. It might seem costly but the improvement on the engine is dramatic which will give you many many more miles out of your vehicle.

Awesome product! Mileage is up and regeneration happens about every 375-425 miles. Once in a while around 300 miles but not often. Very happy!

This product works great either in my Dodge Ram diesel or my wife's Range Rover. Better mileage, runs smoother and even quieter with my Cummins
Thanks for a great ptoduct'

Bought my Ram 2500 4x4 6.7L Cummins in 2017 and have been using the Archoil friction modifier at every oil change. Every time, the oil is clean,black, and still looks good. I also use the friction modifier in my 2012 Hemi Challenger, eliminating the infamous Hemi Tick. It works, unlike some other well known brands.

2003 Ford Explorer 4.0. Rear differentials last maximum 60-80,000 miles. This is due to incompetence in the design. All aluminum gear housing that flexes while the vehicle moves. Hum. This is a cash cow for the dealer. This problem went on for several years. The rest of the vehicle is very good. So I have made it my mission to find a cheap and log range fix. Most all had failures in the bearings and ring and pinion. To the point, I was hearing a whine after installing a new gear set and decided to try the AR 9100. I started driving after putting it in the differential and had a biblical moment. 2 miles down the road and no whine which means the surfaces were no longer metal to metal. I have only one reason. The god’s are not crazy.
