[QUOTE="tyromeo55, post: 3574353, member: 1719"] Why do you think your system is out of oil? There are few reasons to add oil. Even a lot of new compressors are pre-charged with it. Adding too much is not good for a couple of reasons and there is ZERO benefit. The best practice for adding refrigerant (and really the only correct way in a vehicle) is to pull a good vacuum and add by weight. Have not needed to mess with self sealing cans yet. I have a 30# jug or I use a tool that pierces the side of the can. My gauges have a valve at the vehicle port. You can also get a little lead to add to a hose with a ball valve close to the end. Car running..... Close valve on Hi side port at the vehicle tap, (with yellow bottle hose capped, to the bottle or valve body) crack hi and low valves on your gauges to that they can equalize. Remove low side from vehicle. Kill engine (or A/C) wait for a moment, Disconnect Hi side from vehicle. [/QUOTE]
