I ordered the product and it was delivered in a timely manner.

Product arrived smoothly, first time using, instructions were very simple.

To early to tell but in all honesty I think I have encountered a small drop in fuel mileage and a bit harder to start may be me ,but in the product favor I have noticed that my truck does idle smoother and excellerates smoother and faster than before so having said that I have only been using it for a month and a week now waiting to see how it works out for our colder weather here in montana northwest part above Missoula, so thanks for the opportunity to get back to you 👍 😀

I have owned over a dozen diesel trucks during the past forty years, ranging from a 6.9 International in an '85 F-350 to a 7.3 PowerStroke in an '02 Excursion (recently sold after 23 years), to a 6.6 Duramax in a '15 Denali 2500 and several EcoDiesels (across all 3 Generations) in Ram 1500s and Jeeps (current '22 Wrangler HA), and have a current Duramax 3.0 in a GMC AT4 1500. I had never used any fuel additive until trying Archoil Ar6500, so I do not have any other products to compare it with. What I can tell you without reservation is that after a couple of months of use, both the Jeep and AT4 crank quicker, run smoother, and consistently get 3-5% better fuel economy under the same circumstances with the Archoil than without. Your experience may vary, but I will be sticking with it. Happy Smokin'

Great product. Noticeable improvement in performance and fuel economy

Product works as advertised. Bought it twice now

Archoil sent the product very quickly, which was great. Can’t say enough about how great their additive worked, got more MPG, can tell that my pickup ran better more better acceleration. Will definitely buy Archoil additive again. Haven’t had an opportunity to use their winter additive yet, but will try it out when winter comes. Great product!

I had been using your competitors products when switched to yours and noticed a change in the way my truck started to run
For the better
Now this is all I use

I bought product for my 24 diesel pickup and my 12 gas Volvo car. I have really only driven the pickup any miles, but think it helped improve the mileage. I’ll be driving the car for the next month and hope to see improvements there as it needs better gas mileage performance. I expect these products to make more impact on the old car than the new pickup.

i have been using the products for a year now not sure about mileage increase but def use is certainly decreased 2023 Chevy Silverado High Country 3.0 Baby Max.

Fast service and a great product.

Great product. Received it quickly. So far it has made a noticeable difference

Received in a timely manner

I just added it so too soon to give results. Company seems legit. Shipping fast and accurate

Great product and super fast shipping

I made my order 8 days ago and still haven’t received and tracking shows it’s still in Connecticut.
It is now over 30 days and nothing. Absolutely no customer service. I’ve emailed them several times with no response..

Update 10/17/20225: Archoil made it right and reshipped my order no questions asked. I have still not received my original order.

Original Review:
Never received my order, though USPS claimed it was delivered, so it's probably their problem. However Archoil customer service hasn't responded to my inquiry.

Reasonably priced product with great reviews and product well packed and shipped quickly.
