Archoil Substitute?
Am investigating the impact of using Archoil in a 2005 Power Stroke application. Appears that the main beneficial friction reducing ingredient suspended in Archoil is Hex-Boron Nitride (hBN) in a sub-micron size for effective suspension in the carrier. As a firearms manufacturer, we have access to the hBN powder in 0.50 micron form. Since the size of these particles is well smaller than most micro filtration, I was wondering if it could be used as a DIY friction modifier in the Power Stroke engines using Rotella or similar organic oils as the carrier. If it works as well in motor applications as in firearms and bullet coatings this could be an extremely cost efficient alternative to "additives". Anyone had experience with nBN (other than Archoil) in their Power Stroke, or similar size particle additives (experience with filtration elements at this particle size)?

Stick around here until the fall/winter when cold weather sets in and you'll have a bunch of guys willing to try it I'm sure. The cold brings on stiction in the injectors if it is present.
Personally I've used Hotshots Secret with positive long term results on a few trucks. If the Hotshots didn't work ended up replacing the injector.
It would be interesting to see if your additive showed immediate results.

Thanks. Will be probably be testing it on our F350. Same compound as in Archoil it seems, so I expect the benefits and results to be the same if added in the same concentration ratios. Could probably be a cost reducer for those using friction modifiers who want to mix a DIY with their oil changes. Only unknown at this point is filtration concerns. bHN is supplied in our industry in a 0.50 micron size. Haven't seen very many filtration solutions in the Power Strokes that offer less than 2 micron filtration.... so should be good-to-go.

I have tried them all, my personal best with stiction is using the Ceratec from Liqui Moly and using the Liqui Moly MoS2. Also had decent results with motor silk ( think it's over priced). I do know that the 4 ball wear tests indicate between 2% & 4% is the key area for boron and outside that and the wear numbers go up.

Personally, I would post over on BobisTheOilGuy before doing that. The properties of simply adding a solid, even a solid as a very small particle, are almost certainly not the same as formulating a homogeneous liquid that mixes well with the oil.

Our research for oil applications shows that about 5 gram/liter of hBN/oil is optimal. Using the price of hBN in bulk from the suppliers that should add less than $10 to a 14.2 liter oil change for an initial dose. And if the "peening" of the bHN deposits as expected, than retreatments (maintenance doses) at oil changes should fall to less than $5 added.

Will follow up on that post site. Are testing suspension of the particle size in Rotella now. hBN is available down to 70nm size (used in some current lubrication formulations) for about the same cost as the 0.50micron size. At 70nm there may be a MSDS concern however in handling/mixing.
