Hey guys,

So I'm finally tearing in to my AC system and am at the point where I need to add oil to my compressor and dryer. Actually my compressor appears to be filled already, but I want to drain and refill it for peace of mind (unless that is a bad idea and I should just leave it).

Anywho, where am I able to pick up compressor oil? I can't seem to find it at any of my local autoparts places, and ordering it online seems to be my only option. Does Mercedes carry this at their dealerships?

Also where am I able to rent a vacuum pump from to remove all the moisture from the system? Or am I stuck buying one?

So far I have everything out and have flushed the system, just need to oil the compressor and dryer, tighten everything up, pull vacuum for a bit, and charge it.

And sadly I will be using 134 :/
