Best Value. Best results.

Regular use of AR9100 Friction Modifier, AR6500 Diesel Treatment and AR6400-D Diesel Fuel System Cleaner will help protect your engine and fuel system and also boost performance. We recommend using AR9100 at every oil change, AR6400-D every 5,000 miles and AR6500 in every tank of fuel.

★ Ultimate Diesel Kit

The Ultimate Diesel Kit includes three Archoil best-sellers at a huge discount and provides the best results for your engine. Upgrade your oil with AR9100, rapidly restore your diesel fuel system with AR6400-D and get a boost at every fill-up with AR6500 Diesel Treatment.

"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.

"I have been using AR6500 Diesel Treatment for just over four tanks full over the last month. My truck seems to be running smoother, regen cycles have been extended to around 270 miles and my MPG has increased by about 1 MPG (10% increase)." - Danny S, Colorado

★ AR9100 + AR6400-D 

Improve performance and enhance your driving experience by adding AR9100 to your next oil change and Archoil's one-tank treatment AR6400-D to your fuel. AR9100 Friction Modifier's benefits include increased power and response, anti-wear and anti-corrosion protection and injector stiction issues eliminated in 6.0L & 7.3L Power Strokes.

"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
