Worked well for my 6.7 powerstroke!
Archoil makes very good products and I did have a substantial gain in fuel economy on the hwy.With and newer diesel you can expect much more the 17 mpg because of the restrictions of the epa and there def/ diesel particulate filters.But I noticed that my truck had less regen cycles was quite and smoother and on the hwy I hit 21 miles per gallon on a 2017 f350 4 door long bed.Since I've been without for a bit now I'm back down to 18 mpg.

Keep that diesel engine running best
I'm using in my F250 Tremor, 6.7L Powerstroke. With all the chatter about the CP4 failing from wear & friction. I'm not taking any chances. Better mpg also. Last two trips to Colorado pulling our GD Reflection 337RLS, we've gotten over 14mpg.

Going off forum reviews
Don’t really know how to rate this but we are using 1 ounce of this with every tank of fuel in the 3rd generation ecodiesel in the Jeep Wrangler. It’s expensive but an engine is WAY more expensive. We plan on using this even after the Jeep gets the junk off of it. I haven’t seen any proof other than claims on all the forums. There are a few other additives that are recommended I just happen to lean this way.

Use at every fill up
I've been using this at every fill up in a 2021 Ram 2500 6.7 Cummins. I've noticed my truck doesn't regen as frequently when I run this product in every tank. The truck has 30,000 miles, so I can't attest to a "high mileage" vehicle having similar results. However, it does lubricate, increase fuel mileage and help keep your dpf clean. For no more than what it costs when you break it down per tank of fuel, it's 100% worth it to me.
