Which US store shipped it to you if I may ask? I think I previously got it from Amazon, while a number of US bike stores refused to ship it as apparently putting bike oil on a plane can lead to another 9-11 style attack on America.
This topic has been flogged to death on MTBR, so run some searches there, you'll find all the info, opinions, substitute recommendations, etc...
There's also a thread there about using oil vs grease in the air chamber.
The factory red grease in the Revs is PM600 military grease.

I couldn't find it easily in Aus so just used what I had on hand (TF2 Teflon grease, at least it was the same colour ha ha). Read some comments that teflon grease can damage the fork glide rings but no logical reasons were given so I ignored them. For the last service on my 2013 Revs I used Slickoleum for all the O-rings, in the air spring chamber and in the dust wiper cavities. This is what SRAM use for the dust wipers. No issues to date. It's the same thing as Buzzy's Slick Honey.
For the oils I've been using genuine RockShox 5W and 15W interchangeably with Maxima 5W and 15W fork fluids. Maxima is available at one of my local moto stores. RockShox oils are apparently made by Maxima. The bottle shapes look the same but the oils don't have the same colour or smell. They may be using different additives but I'm hoping that if they are from the same manufacturer then at least the weight ratings are equivalent.
Until recently most bike shops in my area were using Motorex. It was probably the cheapest and easiest one to get, judging by the fact that virtually every moto store in 100mile radius carried it almost exclusively. Recently I noticed Motorex is gone and replaced by Motul, probably better distro deals. I expect LBS sheep will follow soon. I'm sure those oils are as good if not better than RockShox/Maxima (Maxima=US made, Motorex=Swiss made...) but the issue is that the weight ratings are not necessarily equivalent between different manufacturers, you need to compare viscosity numbers at various temps, etc, but you work at a refinery, so you already know all that. One source often quoted is this - worth having a read but note it has not been updated in many years and some info is obsolete:

I couldn't be farked comparing viscosity tables or doing subjective ride tests myself, and since I'm able to get hold of RockShox/Maxima I'm sicking with those.
