So I have had the TVS2300 on my car going into three years now. Everything is working fine, but got to thinking and wondering if there is any routine maintenance that is required to be done on the compressor itself. I have a oil separator installed, so the inside of the compressor is still clean like new, but I'm curious if there is a specific oil change interval that is recommended? I have Googled, YouTubed this and search the Roush website but can not find any info pertaining to oil change intervals, how to go about changing it or even what type of replacement oil to use. Not sure if the maintenance info was part of the install manual (don't remember seeing it) but I'm surprised it is not readily available out there on the net somewhere. I'm pretty sure the change intervals are quite long, but would like to confirm and have info on hand when the time comes.
