According to chart I found, the PAG46 is a substitute for the ND8 speced by Honda.
I have used BVA 100 (polyol ester oil) from ackits.com for my two, R134a re-builds. I drained the compressor, evaporator, and receiver/drier in each case, and blew the condensor w/ air to remove any oil. I then installed slightly more than full spec amount of oil.
ackits.com sells a double-end capped Pag46 which is supposed to be a very good PAG. Many PAG's are susceptible to moisture contamination if stored, so it might be worth buying some new oil before charging your car.
I've installed 8oz of oil in my 94 EX and my 99 Subaru Forester. In each case, this is slightly more than spec amount. I simply emptied the 8oz bottle of BVA100 I had purchased. Both systems cool fine, and the 94EX has been working now for over 2 yrs since overhauled.
