A little more info will get you some good advice. Compressor type, model number, load rating, oil in use now etc. I've managed the lubrication program for dozens of compressors of all types from 60 year old recips to new screw compressors so give me something to work with here.

Rgf12, I would like to follow up this post of mine.

That looks to be a very small packaged unit. Have you checked the manual or asked the OEM for advice?

I would contact Compair for the manual as John suggested. Do you have any oil analysis data or is this a time based change? Are there any indications of varnishing? If so you might want to do a flush before the change. If it is an older machine off warranty you can save yourself many $$$$ by going to an aftermarket lubricant. All of the compressor OEMs sell a very expensive "special" lubricant for their machines. Most often they buy a PAG or some other oil in bulk, repackage it, slap their sticker on it and raise the price by double. I've had good experience with going from the synthetic to a dino oil formulated specifically for screw compressors. The additive packages are more robust.
