We have a 20-year-old OTIS hydraulic elevator (5 floors) Our maintenance company is recommending we change the Hydraulic Oil for $8750 since our elevator is over 10 years old. Our maintenance company has been maintaining the elevator since it was installed 20 years and never recommended an oil change before. There is no reason given other than age. Questions:
Do we need to change the oil? Why didn't they recommend changing the oil 10 years ago? Is this a new requirement? Should we wait for a malfunction? Is $8750 a fair price? Plue $2500 to dispose of the oil - $11,250 total
We are in San Diego

I have been working on clearing violations with an abused motel 3 stop inground hydro. Working through all the rust, deteriorated sill, and rotten wood was a real challenge.
I have only been involved with this unit for the last month. Not part of the violations but instead a new issue that maintenance and the guests have been complaining about. Only in the down direction at start there is a loud thud/ bang. Always happens at the 3rd going down and intermittently at the 2nd going down. Even in cartop inspection.
Speaking with maxton tech support about the valve. He quickly mentioned that the piston is most likely sticking and binding up do to lack of lubrication with old or burnt oil. He suggested lubricating the piston with maxglide or other additive. Mentioned to lift the wiper and poor onto the seal. if that stopped the thud then suggested to add a gallon to the power unit.
elmcanic sounds like as you mentioned. The piston is dry. What have you done in this situation??
The better the effort, the better the result.

elmcannic Im certainly no expert, are you? Im sure your not on a forum for just giving advice. Surely you have gained knowledge and opinion from others since 2010. What is more disturbing to me is working for a CET/ QEI that owns a registered elevator company and has never installed or serviced ever. Better yet put unqualified persons to do the work and figure it out on their own. I have worked along side "mechanics" with 10-15 years "experience" and they don't know where to start with wiring better yet read a schematic. no b.s. I have 5 years experience, licensed, and do pretty damn good install/service. Certainly don't pride my self with perfection but I give my best effort.
Ive done a hand full of hydro seal replacements, couple telescopic twin posts (1 beings two weeks ago), 1 casket lift jack, and assembled 4 tradesman twin post jacks. To reseal a jack in this area runs about 8-15k.(depending who does it) But facilities like this one would leave it running rough till an inspector or monitor writes them up. Therefor I reach out to the community for advice and knowledge to attempt a bare minimum fix to resolve the issue. I prefer to give the better effort but they don't want to pay for best result. You definitely should understand this part being in the field as long as you have.
The better the effort, the better the result.
