how much oil RV-2 comp

You should make sure you flushout all the old mineral oil with a special fushing solution availabe from most big auto parts stores. Then with a new drier and with an empty compresser that was either new or flushed out ( remember to replace the crankshaft gas seal and lube it with the new oil type) it needs 10 to 12 ounces of oil. This came right from a Chrysler service book.
