I was told it had R-12 in it. I will be going back with enviro-safe. I usually use PAG oil with it and its molecule is large enough the old hoses seem to work fine.
Thanks for the flush procedure. I will be putting in a new drier and possibly a new expansion valve. I need to get in the dash first and see what is in there.
