Oil expiration
I realize that oils used in servicing movements eventually lose their effectiveness. I've been regularly using D-5, 9010, and 9415 that I bought 7 years ago. They've been kept sealed, cool, and in low humidity the entire time. Also have been playing with 8141, 8217, 9020, and KT-22 bought around the same time. All my oils were rated for 3 or 6 yrs at the time of purchase.
I haven't noticed any performance issues from using these "old" oils but then again I tear down and service the affected movements at least annually (to stay in practice). So I haven't seen any long term effects of oil degradation. Is it time to buy new oils or do you think I can just keep plugging along for now? Anyone else have experience with "expired" oils? |

We have many expired oils at school, don't think it's an issue if you do not notice anything strange going with the viscosity.

Thanks Bas! Out of curiosity what are the recommended oils for Rolex movements these days? And do you treat with Epilame/Fixodrop before reassembly/oiling?

When I was there I used: TEPA for the barrel wall, MR4 as grease (similar to D5), HP1000 for most of the geartrain, 9010 for balance and escape wheel. RL2 on the pallets.
I used fixodrop on the pallet fork, reversers and escape wheel. |
