I dont know why people are so shocked, this is NOT new news. I am not sure if it is posted in the instructions for the UP valves but I have always known that UP recommends only using DOW Corning grease on its valves. I am trying to remember for the life of me where I read it though. It is posted on the UP site though:

Lubrication
This valve has been lubricated for life. It should not need re-lubricating.
The “o” rings in the valve have been lubricated with silicone grease(Dow Corning #55). If it becomes necessary to re-lubricate, do so only with Dow Corning #55 (if you have problems finding this product, it is a stock item with Ultra Precision).
To gain access to the door control mechanism, remove the two screws holding the round cover in place at the end opposite to the quick link connection end. Using a thin piece of music wire, with its end made very smooth so as not to scratch the valve bores, insert it through the hole at the opposite end to the round cover and very carefully push out the cover, followed by the actuating cylinder, spool and spring. Clean with a lint free cloth then lubricate with Dow Corning #55 and re-assemble. Use the music wire to guide the spring into its seat. When inserting the spool it may be necessary to “jiggle” it to get the spring back into its seat at the end of the spool. To remove the strut spool, remove one of the snap rings and pull out the spool.

Even if you use BVM O-ring lube on just your cylinders it will probably make its way back to the valve at sometime so I have never used it in my planes that have a UP valve. You could try removing the cylinder, lubing it a little, actuating the cylinder and then getting out as much of the lube before putting it back in the plane.
