Not sure where to stick this (so if it needs moved, I'm ok with that..Anyone with a Ford PSD using the Archoil Friction Modifier in their oil and does it work as claimed? It's not cheap, 16 ounces is about 35 bucks and needs to be added with every oil change (5000 miles) I just changed my oil and filter and added a 16 ounce bottle of the stuff.Not a big fan of additives but after reading a bunch about it, thought I'd give it a try. My 7.3 cold smokes a bit and idles rough until warmed up. According to Archoil, that is injector misfire cause by sticking spool valves in the HEUI injectors, something that their additive is claimed to eliminate. Engine is basically stock with no emissions controls and a Banks quick spool turbo and 5" straight exhaust. No chip and don't want one.Is it phooey or fact? I'm curious.

I use Molybdenum Disufide, which is NOT for anything with a friction clutch...too slippery and will ruin it in a hurry.It bonds at a molecular level to metal, so does NOT drain off and I also use synthetics, which has a higher film strength. So it does NOT drain off as quickly as most dino oilsThis quote from their web site says it all to me: "...AR9100 is also safe for wet clutches and limited slip differentials..." and why I'd not and stick to molybdenum disulfide additive that is in powdered form (less than 2 micron particle size) and mix it with 1 qt of synthetic engine oil. Oyster blender cost $5 bucks at Goodwill and dedicated for that

The 'additive' in the Archoil is 'Nanoborate' whatever that is.PSD's have an ongoing issue with shuttle (spool) valves sticking in the injectors and causing erratic injection. Like I said, just added a bottle with a fresh oil change and filter and according to Archoil it takes about a hundred miles of driving to have any effect, so it's a 'wait and see with me'. Was curious if anyone else uses it or something similar (there are other 'additives' on the market from what I understand.

I just put some in mine last oil change. I have driven it about 700 miles or so since and it seems to be smoother especially warming up.

It sound nice (with a straight pipe) but being an opposed V8 it should run smoother.People tease me about my noisy diesel (the new ones sound like a gas motor). I don't mind the combustion ignition clatter at all but I would like it to idle a bit smoother and cold start easier. We will see how this stuff works out. I haven't read anything negative about it yet, why I ordered a jug.

According to a post on BITOG it is synthetic sapphire ( the nano ingredient )explains the $$$$$
