Archoil Ultimate Diesel Kit - AR9100 Friction Modifier (16oz) + AR6500 Diesel Treatment (40oz) + AR6400-D Diesel Fuel System Cleaner (12oz)

I use these in my diesel generator, and the results have been great. It’s reduced soot buildup, made cold starts much easier, and gives me real peace of mind knowing my generator will run longer with fewer issues down the road. Excellent product — definitely worth it if you want to extend the life and reliability of your diesel engine.

Worked well in my truck.

Gained 3 mpg when i used the black bottle. Which 20-21 mpg is pretty out of a 05 Dodge 3500. Haven't added the oil yet but im looking foward to the next oil change.

Love archoi!!! Works great and improves fuel mileage HIGHLY recommended

So far ive been using this in my super duties. I wanna say i do feel a difference but nothing life changing. Adding these supplements to the fuel and oil does help with the preventative maintenance. My wrecker has seen the biggest differences mainly in stiction, now its starts up a bit quicker.

Usually this stuff in general really doesn't make a noticeable difference, but.............. This stuff was well worth the $$. I used the oil additive with fresh oil change, T6 & wixx pro filter, and the fuel system cleaner right after with full tank of fuel. Immediately the engine was smoothe and went from 16.5mpg average to 18mpg while driving the same exact way and places. Next tank of fuel I added the fuel treatment and once the went in I am right around 18.8-19.0 mpg and I did reset the fuel economy with oild change. I was also doing a DPF regeneration every 2-3 days if not more, huge red flag !! Now I'm going on 3 weeks with no regen and the DPF gauge drops just from driving Vs auto regeneration. I am sold on this particular brand and suggest to anyone with 5th gen 6.7 Cummins. HotShot diesel stiction elimination is my go to for the 6.0 Power Stroke, but will be trying Amsoil next time I change the oil in it.

Picked up a 6.0 powerstroke for cheap, had a slight miss at idle when cold. The kid I got it from wasnt the best for maintenance, so figured he didnt do oil changes frequently. Not good for a heui injection system. Changed oil and added the archoil, plus the black fuel treatment bottle to the tank. About 200 miles later the truck was idling nice and smooth. Didnt notice any uptick in power or fuel economy, but it spends most of its time towing so mpg isnt number 1 priority. Dont know if ill continue using the oil addative or not. I dont usualy reccomend oil addatives, bht it was cheap vs a set of injectors. Probably keep using the fuel addative for now, it pencils out pretty cheap per gallon treated vs other fuel addatives. Pull an oil sample when its time to change oil and see what the lab says.

I thought i would give this stuff a try, My 1999 F250 with 150k miles was getting real sluggish on cold weather starts and not even real cold only like 30's +/ - deg. I tell you I'm amazed ! those temps don't even phase it after only a 175 mile round trip right after a oil change and adding all 3 products, outstanding !

Delivered to West Australia in reasonable time, well packed, original products, all good

Been using archoil for about a year now on my 7.3 powerstroke , it works almost instantly you’ll see on a cold start when you fire up and get that white puff of exhaust from The tail pipe with archoil that goes away . Even use it on my tractor and I’ve noticed a huge difference in the injectors I’ve had sticky injectors for awhile , poured the stiction and injector cleaner in one tank of fuel and it cleared up right away no more white cloud for 5 min till it warmed up it was instant clear and running smooth. Will continue to purchase .

A must have kit for all 6.0 owners. This stuff is liquid gold. When I first bought my truck it had the typical stiction issues and fuel system/turbo issues that 6.0 liters have. After using these products only once, it removed the stiction problem, cleaned my turbo and improved my fuel economy. I went from 3.8 km/litre to 6.2 using it as a daily driver, and on a long trip, got 7.3 km/liter. Outstanding!! I use this at every oil change. Worth every penny :o)

1995 powerstroke was very smoky on cold start up. Archoil 9100 virtually eliminated this when added to the oil change. I am very impressed. I will need a tank or two of runtime to see if the fuel additives live up to the claims, I am confident they will.

This product is expensive but works wonders. Helps with injector stiction, better performance and fuel economy. I've been running this stuff for a few years now and I won't go back. The peace of mind that my engine has another layer of protection is priceless. I would buy again.
