Thanks... Yeah I am privy to the information you described.. Its just that these old MB's have these sensetive, (specific pre requisites), systems and I don't want to screw it up..

That being said, I can't find any places around here that carry these types of specific oils and such for my "old sensetive R-12 system"... Hence, the questions for PAG and such...

I will be using enviro-safe, an R-12 replacement / substitute. I guess I will simply order the oil from envirosafe which is supposed to be a great oil that is
Compatible with mineral, ester or pag oils... I tried purchasing some polymax2 from an online source but I think they are a fly by night operation and I must dispute for a refund... hohum...

Thanks again for all the help.....

Im off to get cleaned up as I just had enough of screwin around for 3 hrs getting that damn new expansion valve replaced... (what a PITA)


Cheers!
