AR9100 Oil Additive
Richard F.C. (Tacoma, WA, US)
Great product

I use the fuel additive and oil additive every fuel up and every oil change I can sure tell a difference in how the engine sound and performs. I will continue to use.

Archoil 97 powerstroke

I do believe the exhaust color on startup of the old 7.3 definitely improved. Used fuel additive first and then oil additive also. I will use the oil additive again with my next oil change 👍

AR6400-G

First time using the concentrated gas cleaner. If anything like the AR6400-D should be great.

If you have a emissions controlled truck, please buy this product and be strict about using it

I have a 2015 ram 3500 6.7 that i tow 30k miles a year with, bought the truck at 100k miles and noticed from 140k to 160k miles on it that the truck was running through DEF fluid compared to when i first got the truck, about 10k miles ago i got a Banks idash for the truck and noticed it was in regen a lot (i just couldn’t tell because it must have been in regen while i was driving all the time vs static regen while in Park) after putting about 40k miles on the truck after i got it i did become lazy about adding the AR6500 in it so I figured out why my truck was going through so much DEF fluid, it was because i was being lazy about adding the AR6500 at every other fuel up, i know all of archoil’s products are expensive but I beg you to get this product, it truly is worth it, don’t just use it for a short time and make up your mind about it, run it for several thousand miles and prove it to yourself, with the price of fuel so high i know paying for this product and adding it to your fuel is the last thing you wana do but if you have a DPF truck and you care about longevity then it will pay off in the long run, also if you have an emissions controlled truck then you have the money to put this in the fuel, if not then you probably shouldn’t have a newer diesel truck, don’t be lazy just buy it.

Archoil - For Any Engine

I've got about 300 miles now on my 250,000 mile Toyota 22R engine and the engine feels pretty good and seems like it is smoothing out a little. I couldn't see any smoke coming out the tailpipe before adding archoil, but I know the engine was using some oil about a quart every 3000 miles. I'm still watching to see in more driving time if the oil consumption becomes less. But yeah, the engine does feel a bit smoother and should continue to do so as I drive my 4x4 truck more. Archoil seems very well be the safest engine oil additive with noticeable results.

Since using the Diesel Treatment on every fill up, I started to see a gradually increase in MPG. I have not used the other products yet, since I have not done an oil change. But I am curious in how this will improve the engine oil in the engine that has over 300,000+ miles on the odometer.

Love Archoil

I've used the Friction Modifier and fuel treatment for a few years, also use the fuel cleaner now. Definitely makes my 6.0 start easier and run smoother I use the winter additive during colder months.

Works wonders

Works Great

Been using this stuff for years in both 6.0 and 7.3 trucks haven't had an injector issues since I've been using it for the cost with a DINO 15w40 oil change I'd say the product works and pays for itself in the long term if you can get 200k more out of your injectors

Great product for the price.

It came to me quickly and in these days we need all the help we can get saving a few extra dollars at the pump. Thanks Archoil!

Revived a rough running 7.3

I put a bottle in a tank of old diesel fuel in an E350 (370k miles) that had been sitting for a year. It ran for a few miles then must have picked up algae and started running rough. After changing the fuel filter and adding the AR6400-D it’s cleared right up and continued to run really well. I’m about 200miles in now with topped off fresh fuel still running good.

Repeat Customer Extremely Satisfied

I live in a small mountain town in Colorado. The winters often see weeks at a time with sub zero daily high temps. I run the winter fuel additive through the winter, and have had trouble free driving for two years now. I use the oil additive, and regardless of oil, notice quieter injectors and happier cold starts with the oil additive. The summer fuel additive contributed a small bump in economy, and less smoke on start up. Together this additive package seems to keep my 27 year old Power Stroke chugging along. I recommend archoil to everyone who I talk to about Diesel trucks, especially in harsh cold climates.

Seems to help vibration and gas mileage.

I used AR9100 in two cars, an '08 Mercedes E350 and a '94 Ford Taurus GL. In the old Taurus, there is a noticeable improvement in vibration during warm-up and improved gas mileage under both highway and local driving conditions. The Mercedes was already running at peak performance, and there has been no change with the AR9100 added.

Used in my 2012 Can Am 900 commander that was running rough on startup and bogged down on low speed. Now it’s running perfectly.

Charles L. (Albuquerque, NM, US)

I have a stock 2009 6.7 Cummins with 85k miles. for the past year my mpg has been decreasing little by little The best mpg was 12.5. I used one treatment of the AR 6400-D diesel fuel system cleaner. It took about two hundred miles before I noticed any change. Happy to inform you all that my mpg increased to 19.6. Very satisfied with this product!!
