Also, the claimed improvement - did you notice that their website says:
Quote:
AR9100 Nanoborate reduces friction to coefficients of 0.037, half again the friction coefficient of 'micro boron', and a fraction of traditional lubricants like zinc, phosphorous and other additives presently used in popular oil and grease formulations.
Read that carefully and note that it give the COF relative to additives,
not to oil? Is that correct?

lawnguy I really like the specs (.003 coefficient of friction) of the AR9300 but due to cost I just ordered a gallon of Archoil AR9100 with .03 coefficient of friction and a quart of AR6200 fuel additive. Winter is coming on and I have a lot of engines that have not had the oil changed in a few years around the place.
By going with the gallon size AR9100 is $2-3 less expensive for a 5 quart engine than MoS2 the way I was buying it and it has a lower coefficient of friction the best I can tell. It is about $20 less expensive than Ceratex for the same engine yet is still a nano technology additive with a lot of usage history on the web.
kschachn your question is one I have been trying to find the answer to but I have found no lab results just marketing statements. What is needed is data using the treated motor oil that will be in the engine.
It is so much less expensive than the Ceratec for a nano additive but the main attraction is its internal cleaning ability if the marketing hype is remotely true.
Our engines that we service around the place are 70's through early 90's for the most part so I would like to clean them up but after running the Rotella 5W-40 T6 for a few years they may be clean to the max. In that they can set without starting for 6 months or longer having the parts coated with lube should stop/reduce cold start ups is a major reason I want to try the Archoil 9100 at this time plus some only get the oil changed every 5 years or so.
The Archoil AR6200 is less expensive than Seafoam to keep gas fresh and should be good for the diesel injectors and injector pumps.
If pressed for time I may just change filters for now and add the AR9100 in the tractors and F700 truck so some of the cleaning can happen before going with new oil next spring.
I have mixed feeling about the value of most additives when using a top notch oil like Rotella T6 especially. I like doing is as a hobby and it is cheaper than some hobbies.
