I found the instructions and pictures on how to change the oil on the RX-330. They seemed very similar to the RX-300 but when i got under the car, I could not find a way from the top or bottom to get to the filter. I could put my whole hand on it from the bottom but my neighbor, who has every tool known to man, and I tried fro about an hour and finally gave up. We changed the oil and not the filter and unless we can figure it out, I will have to submit to the dealer or similar oil change place. Any suggestions on what tool someone has used, would be great. The filter was so tight, there was no way to loosen it by hand and it is recessed with equipment to the right and left of it, making it very hard to have any leverage!
