Best Value. Best results.

Regular use of AR9100 Friction Modifier, AR6500 Diesel Treatment and AR6400-D Diesel Fuel System Cleaner will help protect your engine and fuel system and also boost performance. We recommend using AR9100 at every oil change, AR6400-D every 5,000 miles and AR6500 in every tank of fuel.

> Diesel Starter Kit 

AR6400-D rapidly restores the diesel fuel system, removing heavy soot and carbon build-up from the key components - injectors, turbos and DPFs. AR6400-D should be used every 5,000 miles or as required.

For the best results, use AR6500 at every fill-up. AR6500 has been formulated to address issues with modern diesel fuels by cleaning, lubricating and protecting your fuel system while also incorporating Archoil's combustion modifier technology and a cetane boost to increase power and response. The 16.7 oz bottle included in the Diesel Starter Kit treats up to 165 gallons.

"I have been using AR6500 Diesel Treatment for just over four tanks full over the last month. My truck seems to be running smoother, regen cycles have been extended to around 270 miles and my MPG has increased by about 1 MPG (10% increase)." - Danny S, Colorado

"My 20 year old truck had been a little cranky as of recent starting below the freezing mark. The smaller the number outside the more cranking has been needed. On my second tank of the Archoil winter additive and at 18 degrees she fired up in moments!" - Matt M, MT

Excellent products!

I have a 2000 Ford F-250 with a 7.3. This was my second purchase of the ultimate diesel kit.

Prior to using the products cold starts were difficult, producing heavy smoke and the injectors were extremely noisy all the time. Performance was sluggish.

After starting the use of the archoil products the improvement was immediate and dramatic. Starts quickly,
No more heavy smoke, injectors are much quieter and a better performance and mileage.

If you have a hard to start, smoke belching injector clattering 7.3 this will give you a much better performing ride.
