First off, how about how many oz's of R134a is needed? Second, what kind of oil? There are 2 kinds that i know of, PAG????? and something that starts with an "E". I noticed I have a retrofited R134a sticker that a dealer put on my fan that says to use 2 lbs of R134a, 12 oz's of "E" oil. I dont know if that's going to be the same for the LT1 compressor. I'll have all the thirdgen a/c components except the LT1 compressor.
