Thanks for the quick reply, carguy7. So based on the discussions, it is not uncommon to not see any indication of oil in the filter? Hmmm. This is all new to me since with all my other cars, including my es300, I have always seen some oil when I remove the filter regardless of how long the car sat before I removed the filter. I have checked the RX330 oil at the dipstick since the oil change and the oil still looks clean. I will try removing th filter and see if I have the same dry filter.
