I spend a good part of my time teaching in the vocational schools and universities, as well as oil fields and power plants, industrial plants, etc. about industrial lubrication.
I often give out CD's. Sometimes with my website in autorun, as a lot of times they have no access to the internet, and most of my site is dedicated to industrial lubrication.
Here education is sevberely lacking, equipment comes with bad recomendations (I saw a Chinese made front end loader the other day that recommeded the use in the convertir (Komatsu copy) oil that meets SAE 40, TDH ISO 46, API GL-5 specs. I had to take the chinese manuals, the equipment and the mechanics and figure out the best oils for each compartment.
xI find some hydraulic oils that oxidize to double viscosity in 500 hours of operation. We have a country where the lowest bidder gets a lot of contracts, and there is no standard for what you can call "hydraulic oil", although motor oil must be at least a CD when imported. (they forgot to regulate the retail side) So some people import CC oils as hydraulic oils and sell them as motor oils.
Some manufacturere os equipment have told me they don't recommend the latest oils because people won't by their equipment if they are told they need CI-4, borate gear oils, or anything else not found in the corner oil shop.
I check in this section as time permits, which has not been a lot lately.
