Im using 134a tonight to charge my system... .i read that it used 80% of the capacity that r12 uses... my sticker is no longer readable... What is the correct amount of lbs to put into my system and what is the correct amount of pg 150 oil to use...


I did a complete flush with a citrus smelling ac flush... I will spread the oil out to the condenser compressor and drier.... This is my first attempt on this system i have no clue if it leaks or not but the drier and compressor are new... any advice would be appreciated... I cleaned the evaporator with cleaner and a snaked brake line to reach all the sides... i shot the cleaner through the brake line and onto the evaporator... squeaky clean...

I knew it was here somewhere.

thanks for that i was looking all over for it... new question though... my new compressor says it was shipped without oil but when i removed the plate for install my hosing bracket... oil poured out of the holes....

perhaps you got a compressor someone returned to the store. I'd be concerned if it was full of oil...

good point i will call them.. its a 4 seasons compressor

Since you've already flushed the system, this would be the PERFECT time to put it back with R12. It would cost VERY little more than 134 in today's market and make it cool better and last longer.

yeah your right on that one... i think i may actually switch back to r12... i am nitrogen testing first to make sure i dont blow my money... i got set back from the freon temp sensor breaking off inside the old drier when removing
