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.

> 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. 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 16.7 oz bottle included in the Diesel Starter Kit treats up to 165 gallons.

"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 AR6400-D treatment 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 + AR6500

This limited-time kit will restore power and boost your vehicle's performance. AR9100 Friction Modifier protects engines and is suitable for treating injector stiction in 6.0L & 7.3L Power Strokes. AR6500 cleans, lubricates and protects the fuel system while also packing a powerful cetane boost and Archoil's combustion modifier technology for improved performance after every fill-up.

"We just bought a 2015 F350 and are using the fuel and oil additives. So far so good. Great mileage and runs so quiet and smooth. Only 69,000 miles and plan on many more using these products." - Forest, WA

Great product

I use AR9100 at every oil change, and fuel treatment every other tank full, keeps my 2004 6.0 with 290000+ mi running great!

Mark B. (Dallas, TX, US)

224,545 miles on original injectors on 2004 6.0 ..... thought it was finally time to replace them..... truck was running bad.... jerk... surge.... hard to get started... replaced the IPR screen.... installed a new FICM power supply board... helped it some..... changed the oil & all filters ..... added both the oil additive & the fuel additive "2oz to 10 gal"...... & AMAZINGLY ENOUGH...... it fires right up & runs smooth. . So smooth I can run it on the cruise control without it Jerking the drive train! I'm sure it's just a Matter of time before the injectors will have to be replaced...... but I'm going to get every last mile out of them as possible !
