"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 16.7 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 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)

Great product!

Great product! I have used them in my 2016-F 350 6.7 Crew Cab for the past couple of years. I just started adding their gas products to my wife's 2017 Ford Edge. I'm very pleased with the results.

AWESOME PRODUCTS

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. Love that you help Military coming back from duty and entering the work force.
