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.

Did exactly what I needed.

What a difference this product makes in my powerstroke. Towing and gas efficiency is up, immediately feel how much smoother amd quiet my F350 superduty diesel runs. I use all the combined products as directed and is great.

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

With all of the "snake oils" on the market,its hard to tell what's real from fake,but this product is as real as they get.If you own a vehicle with a diesel engine,this product is the best thing you can use,for a maintenance supplement,or to restore performance,now common sense should tell you it won't rebuild your motor,but if you have injector issues,and performance is fading,before going broke replacing injectors and stuff like that,give this a shot,you will be amazed!

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.

Works amazing, truck ran better quickly

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.

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!!

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

Cleared up white smoke on startup, runs noticeably better, haven't tried other brands so nothing to compare it to.
