- 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.

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.

Love this product. If you have a diesel do yourself a favor and get it. Buddy turned me on to this. Oil change in goes the additive at each oil change, every fill up put the injectior cleaner and fuel system in the tank. Got better mpg. Protect your investment

Delivered with care and speed

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 !

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)

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

Great stuff!!

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 .

Truck definitely starts better using these products fuel additive has my old 6.0L running nice under load.
