Engine oil pressure

[ErixCZE]

On my last flight I got a R ENGINE OIL PRESS warning after 4 or so hours of cruise flight. I decided to proceed to nearest airport and the moment I retarded the throttles I got the same warning for the left engine. Any ideas what may have caused this?

Both warning disappeared after descending below FL200 and adding power.

How’s your engine oil quantity? If you’ve been flying the same Challenger airframe a lot, but not replenishing engine oil it’s likely the reservoir is low. 

You can access the engine oil replenishment system window through the ground services menu. 
 

Instructions for how to use it are in this video:

I had no idea I had to do that. I've though there were no maintenance features implemented. Thanks

That's not classified as maintenance technically. You're not changing the oil, you're merely filling it up from the reservoir, similar to filling her with fuel. Maintenance on oil would be the 50 hour replacement.

would it be bad to run it for a while with low pressure..say until I got to my dest and fill it there
