That's not entirely correct. There is a new R-134a oil available that does not have to have the old 12 oil pumped out. You can buy that kit at Wal-Mart for $33 and it will probably be enough for the D. BUT-- you do have to get all the 12 gas out. I had a friend with a pump and reclamation canister to store it. And it does not require more pressure. It might be more effective with more pressure, but it does not require more pressure. But you are probably better off (living in Arizona) to get 12 if you can. I'm in Houston... thinking I might regret going to 134a. We'll see.......
