"My engine is noticeably quieter and a lot more responsive. It runs better now than it did in 2006 when I bought it!"


Fully restore and maintain your vehicle's fuel system with this kit.

AR6400-D delivers a rapid deep clean to remove carbon build-up from injectors and key fuel system components. AR6500 boosts cetane, improves lubricity and keeps the fuel system clean to increase MPG and prevent premature failure.

"I had some turbo lag - gone. Engine had rough idle at times - gone. Fuel economy has increased between 1 and 1.5 MPG."

"As a former mechanic I never believed in additives but this is my 3rd purchase of this product and used on 3 different vehicles with great results. On my BMW X5 it made the idle smooth and the MPG up by 2. On my LML increased the regeneration interval from 300 to 600 miles."

AR6400-D Diesel Fuel System Cleaner

"The engine noise became noticeably quieter after about 20 to 30 miles. Before Archoil this truck was lucky to get 14 MPG on the highway. I drove back from New Mexico with a slight tailwind and AR6500. One leg I got 20 MPG!! This truck in 60,000 miles has NEVER gotten 20 MPG before!"

AR6500 Diesel Treatment

"I use it in all my diesel engines. I was amazed when I pulled the valve covers. It was showroom clean - no sludge, no blowby residue, nothing. Could easily read the serial numbers on the injectors. As far as stiction goes, I don't have any with my Power Stroke and it runs smooth and fires right up."

Woke my 6.7 up

I ran the cleaner for a tank and now the additive. The truck is more responsive and gained 1-2 mpg. Seems to work better than the hot shots I was using before

I have a 2007 f250 6.0, been having some shuttering issues and no power almost like it was skipping. Not bullet proofed and no programs just stock, I've tried nearly everything on the shelf, lucas, hotshots secret, and diesel kleen, the only thing that helped a little with power and decrease the shuttering was diesel kleen. Then I saw the ad for archoil and was skeptical because of the price like hotshots secret, I was almost to the point of giving up on it and just selling it. No, I promise I'm a real person and not paid by archoil, so I gave the truck 1 last shot. Still skeptical at this point, just another diesel treatment... I bought all 3 in the kit and when I changed my oil and used the oil additive along with the fuel cleaner and cleaner booster I felt like I was driving a new truck, no more shuttering and no more lag, talk about power. Man, the boost and response of that turbo is awesome and the power going up hills. Haven't checked fuel mileage, but why at this point. This is a major improvement and will buy again. So you can quit being skeptical and spend the money, trust me. Thanks guys and or gals at archoil....
