You still have to get the old R12 oil out by flushing it. The two oils are not compatible so your looking at problems by mixing the two like early compressor failure possibly. I don't see a backyard mechanic with the proper tools to flush and evacuate an AC system.
I just mean if your going to go to the trouble to do the job then do it right the first time.
Im an aviation electrician and work on military jets so maybe I'm a little to over zealous about doing preventitive maintenance when possible.

This is possible, when I was told by my mechanic he knows me for one and what Im capable of, and two, we were talking about a system that is currently open on my car (meaning, I have to do a compressor swap as is, so my new (used)compressor will be empty)

so my information was in regards to something in the middle of both ends of the spectrum.

I just did a conversion on a suburban this past weekend and the oil that comes with the conversion kit is definetly compatible with the r12 oil. just go to the autoparts store and buy the kit for no more than 35 dollars, you might have to buy the extra cans of R134 refrigerant to make up the amount that your system requires. Remember to look up the amount in ounces of refrigerant that your system requires,that total includes the oil that you are adding with the kit. IT IS IMPORTANT NOT TO OVERCHARGE THE SYSTEM... as the kit also informs you to only fill up to 80 percent. follow the instruccions on the packaging, its is very simple.. the amount required for your system should be on label on top of the accumulator/dryer it itll be in lbs. good luck..
