Archoil AR6500 Diesel Treatment (40 oz) Two Pack - Treats 800 Gallons, Diesel Fuel Additive - Lubricity Improver, Injector Cleaner, DPF & Turbo Deposit Control, Cetane Booster

Works great, my truck loves it, saves me fuel and engine runs smoother, also less regens .

Great results , have been using for about a year and a half on our Baby Diesel 4.0 Chevy 1500 pick up. Highest mileage has been 41.4 per gallon but around 30 to 31 average driving city and highway. Fewer and shorter regenerations. Very satisfied with the product would recommend.

Our truck was starting to have occasional issues with turbo on our diesel engine. Things were running, but not as well as usual. First we ran the Archoil cleaner through a tank of fuel. Now, we use Atchoil additive regularly. No more issues, and our MPG has increased too.

So fair its working very well helps with easier starts and smother running very good product

Great product. Cut back on frequency and duration of regens. Been using faithfully for about a year.

Fuel mileage has increased since I started using this at every fill up, close to 2-3 mpg.

Best diesel treatment I've ever used. Just wish they made it large enough for semi trucks. It costs a fortune to run through my semi. I buy 4 bottles of the cleaner, every oil change. I could go through a bottle of the treatment a week. Great for a diesel pickup. Not practical for a semi but I tell ya, it works great.

This stuff works well in my 2005 5.9 Cummins. I don’t see a mileage gain, but engine runs and idles smoother.

Good product noticed big difference on my Mercedes diesel

I found it helps with my mileage and trucks runs smoother !

Works very well, had to order again

Works well

Using it in my 6.7 f350 Diesel to try and keep the CP4 from blowing up. Seems decent.
