"Since I started using Archoil products on my 2005 Ford 6.0 diesel I am pleased to report that my engine starts easier even on the coldest mornings, it runs quieter, the turbo responds perfectly and my fuel mileage has improved." - Frank R, NY
> Diesel Starter Kit
AR6400-D rapidly restores the diesel fuel system, removing heavy soot and carbon build-up from the key components - injectors, turbos and DPFs. AR6400-D should be used every 5,000 miles or as required.
For the best results, use AR6500 at every fill-up between AR6400-D treatments. AR6500 has been formulated to address issues with modern diesel fuels by cleaning, lubricating and protecting your fuel system while also incorporating Archoil's combustion modifier technology and a cetane boost to increase power and response. The 16.5 oz bottle included in the Diesel Starter Kit treats up to 165 gallons.

"My 1995 F350 was starting very rough and smoking for a while before clearing up. I have only run 1,000 miles with both additives in but I noticed a significant improvement in cold weather starting after a few hundred miles. The truck starts easier, doesn’t sound/feel like it’s missing and barely smokes at all." - M. Wells (1995 F350)
> AR9100 Two Pack
AR9100 oil additive is suitable for all gas and diesel engines, providing extreme pressure protection, reduced friction, engine deposit reduction and extended oil drain intervals. AR9100 forms a solid boundary lubricating film which protects engines and extends component life.
AR9100 eliminates hard/cold start issues caused by HEUI injector misfires in 6.0L & 7.3L Power Strokes.

"I was skeptical having been mostly disappointed over the years by almost every additive. After adding this to my 2006 Duramax work van I noticed a much smoother operating engine and all my subsequent morning starts are instantaneous. I will be using in all my vehicles from now on." - Chad L, Oregon
