"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.

"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.

"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

Powerstroke performance

My 2000 Superduty 7.3 Powerstroke is stock and what I would consider ordinary in performance. It has 240K and the only issue really is a minor oil leak which I am taking care of this summer. Over the past couple of years I felt like I could notice a drop in power and acceleration. I service the truck myself completely on a more regular interval than anyone else I know, so the truck is definitely well cared for and not abused.
A friend told me about Archoil additives and I thought "no way."
Well, I am a believer now! I first put in the oil additive and within 100 -150 miles or so it just felt different... smoother and easier starting. After I put in the fuel additive I was amazed how much power I had been missing out on, it's like a new truck!
Thanks Archoil!

No more black smoke

Archoil’s additives took care of my Powerstroke’s rich fuel problem. Had 6500 miles since my last oil change (I know. I know. That was stupidit not to have done it sooner). But an oil change with T-6, Archoil’s oil additive, and gas their additives took care of the black smoke. Very glad I happened to discover their additives.

Starts better! Not much increase in mpg. Overall guess it hasn't hurt anything!

Jimmy L.S. (Haines, OR, US)

It would be nice if it was that price , was a every day price. I was having trouble with my power steering on 06 f250 deisel 4x4 superduty, I took two ounces of power steering fluid out and poured in 2 ounces of 9100 arch oil in it. Have not had a problem with power steering again.
