ArchoilUltimate Diesel Kit - AR9100 Friction Modifier (16oz) + AR6500 Diesel Treatment (40oz) + AR6400-D Diesel Fuel System Cleaner (12oz)

The Archoil Ultimate Diesel Kit is fantastic! After using the AR9100 and the included additives, I noticed my truck runs smoother, quieter, and with better throttle response. Cold starts are easier, and I’ve seen a small bump in fuel economy as well. Everything is packaged well and easy to use. Definitely worth the investment for anyone wanting to protect their engine and improve performance. Highly recommend!

Great product!

What a difference this product makes in my powerstroke. Towing and gas efficiency is up, immediately feel how much smoother amd quiet my F350 superduty diesel runs. I use all the combined products as directed and is great.

With all of the "snake oils" on the market,its hard to tell what's real from fake,but this product is as real as they get.If you own a vehicle with a diesel engine,this product is the best thing you can use,for a maintenance supplement,or to restore performance,now common sense should tell you it won't rebuild your motor,but if you have injector issues,and performance is fading,before going broke replacing injectors and stuff like that,give this a shot,you will be amazed!

Excellent product, easy to use, has a preset measure. Works great as needed.

Shipping was good.

Works exactly as shown,, milagage went up from 11 to 12 mpg to 13 or 14 mpg

Great products I can tell with my F-350 when it on board.
