110K miles on our RX330. I use Pennzoil Platinum 5W30 in the winter and 10W30 in the summer. Pretty sure this run was 5W30. I change the oil every 5K and change the filter every 10K. I usually use Mobil 1 oil filters, but got the Autozone special this time and used a K&N. The air filter is Toyota OEM and I usually change every 15K. BTW, the first run on 3/9/06 was Mobil 1 EP. The others have all been PP. Appreciate any comments.
