Since Oasis is land side in T4, one could check in at T5, go to T4 for the lounge, and then return (allowing sufficient time for the air train, security, and possible delays) to T5 for the flight. Not ideal, and of course if the airline doesn't give access to Oasis, one must obtain it from other means (DL SC membership, Priority Pass?).
