AR6500 Diesel Treatment
Jim M. (San Jose, CA, US)
Seems to work as advertised, but way too expensive.

I have a one year old 2021 Chevrolet 3500HD with a 6.6 liter Duramax Diesel L5P Engine. It is bone stock and will stay that way (ie emissions intact). The truck currently has 16,000 miles on it and I started using the AR6500 at about 8,000 miles. The engine idles smoother and does fewer regenerations using the product. As far a fuel mileage is concerned, not a lot of difference as far as I can tell. The truck will get 18 to 21 mpg not towing on flat highway driving and 9-12 mpg towing a 12,000 fifth wheel camper depending on terrain. I believe this product works well but the price seems excessive, I would like to find a less expensive alternative. Diesel fuel is already too expensive and this additive make it worse.

Doing the job

Bought this on a special and as far as I can tell it is doing the task set for it. Good price was the motivation.

Good overall fuel additive

Good all around fuel additive for general use. Engine runs smoother and quieter immediately upon use and I like to use as a maintenance additive.

The Best Stuff!

I have used Archoil products since I bought my ‘05 F350 6.0L 5 years ago. I had a stiction issue which was resolved by AR6400 & AR9100 (oil additive). When winter came & freezing temperatures I needed an anti-gel product. AR6300 was my only option since I had great results with the other two products. Never had a problem with cold starts. The truck runs great! I highly recommend all Archoil products for diesel vehicle owners.

Archoil

Did quite down the motor some. But unfortunately for me the hard starts did not get any better. Truck starts and runs rough for about 3-5 min and smokes until it gets a little warm. I will try this again next oil change and possibly shim my injectors and do new o rings on all them.

Satisfied!

You guys are making Preventative Maintenance a whole lot easier! My 2002 F250 7.3L Diesel loves Archoil!

Works like promised

Only diesel additive I use. Noticed the truck ran quieter with the fuel system cleaner.
Will continue to use Archoil products!

Muy bueno!

Excelente producto, lo uso en mi Lobo ecoboost desde hace dos años, he observado através de este tiempo que hay menos carbón en el escape y no "cascabelea". Lo seguiré usando.

Archoil guys: It really needs to be available again in a P1 kit.

Works great in my 03 F350. No issues with gelling and my truck does run better and starts easier, even after sitting for extended periods.

Needs to be available again in a p1 kit!!!

Awesome

It's unbelievable how this stuff has smoothes out my idle and its so much easier to start. I will be buying again

Great Stuff

My experience on both gasoline and diesel (2016 MY MB Sprinter) is that the improved mileage (ca 1mpg+) helps pay for keeping injectors and engine in good condion as evidenced by smooth and reliable performance on high mileage vehicles.

Great stuff!

Awesome product! I noticed a difference in my 99 powerstroke in just a few miles. The engine quited down and runs a lot smoother

New pep

I used this in my 2004 Mercedes S430 with 220,000 miles on the odometer. I experienced an immediate increase in responsiveness and some zip-bam-boom on acceleration.

Really pleased.

Funkiest bottle I've ever seen. But, every Archoil product I have ever used has worked incredibly well. Use anything you make for the Ford 6.0 Powerstroke. If you get around to making a transmission additive, let me know. I'll be the first one to buy it.

The Archoil Fix For Ford Power Stroke
Kevin J. (Peoria, AZ, US)
7.3 Diesel 2003

It works! Last oil change I flushed my HPOP reservoir with Seafoam, then added half & half synthetic Rotella (hard to find right now) and ArchOil to the reservoir. The engine now runs smoother, quieter and starts with ease. Hopefully this will preserve the injectors until the top-end O-rings (all of them, HPOP to the pedestal) need to be replaced. I'm convinced that Archoil not only works but will help prolong the life of the engine.

good product
