- 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.

This is an outstanding product that works well with my diesel truck. Very satisfied overall and will continue using these products.

My '95 7.3 powerstroke appreciates these products. It starts better, smoothens up faster especially when cold and overall just runs better. I've considered adding some to my 7.3 idi to see if she loves it too.

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

Works great for a 2003 Ford F250

seems to be working good

Did exactly what I needed.

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!!

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

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.
