Archoil AR9100 Friction Modifier (16oz) Oil Additive for All Vehicles - Powerstroke Cold Starts, Eliminates Injector Problems

Made a noticeable difference with fuel economy within the first 100 miles. Using a programmer chip for improved fuel economy. After adding Archoil I was seeing 1 to 1.5 mpg increase on the monitor while driving on a flat highway.

helped my 7.3. starts easier and smokes less

had a lifter sticking and as soon as i changed the oil and added this archoil it unstuck and ran like new

Very good product, helps with the starting of my 6 liter

use this every oil change works great

After one month, I noticed a smoother acceleration and better acceleration than before. This is a GM V6 vortec engine with 220,000 miles. It handles better than before I added it the friction modifier. I recommend this product.

I used to use a competitor's additive. at around 100,000 miles the turbo would fail. Since I started using Archoil 9100 I have not had a turbo failure. I have put 250,000 miles on this turbo with no failures. The truck has over 418,000 miles on it now.

I first started running Archoil 9100 and their 6200 fuel treatment in my 2006 Ford 6.0 diesel approximately 15 years ago. Shortly after adding Archoil 9100 to an oil change I noticed my injectors quieted down and the engine was running smoother. I continued to add Archoil 9100 religiously to every oil change in my stock 6.0 diesel until selling it with 130,000 miles. the engine was purring when I sold it but it was time to downsize. After selling my 6.0 I purchased a 1995 Ford 5.8 gasser as a beater, I replaced the engine and after break in have been running Archoil 9100 as well as their 6200 fuel additive in that to date. That ruck idols smoother than some newer vehicles I've been in. I have since purchased another low mileage 6.0 diesel and immediately changed the oil adding Archoil 9100 and like my last 6.0 could hear a difference in the injectors shortly after. I will continue to run Archoil products because I have heard and felt the difference they make in an engine

I had used this product in the past but because it was hard to find and expensive I decided to try something else. Well the stiction was returning so I broke down and ordered it from Archoil direct. It's the only product I've found that works. I wish it was more affordable but you get what you pay for.

It work a miracle on my 2007 f350 6.0 powerstroke. My truck was going to the shop for injectors because the stiction was so bad I could barely drive my truck. 2 days before it was set to go in the someone recommended that I do an oil change with amsoil and the AR9100. After the oil change the stiction was basically gone. It's been 7 months now and multiple oil changes and my truck has been doing great. I daily drive and only time I really have stiction is first thing in the morning. I let the truck idle till it's up to temp and then it's good to go. I definitely recommend this product.
