Thanks for the advice from you all. I should have said also that I am not a do it your selfer. Girl, whose husband is hands off my car, for such things.
I did take the car to the Toyota place to have the service, (not the Lexus dealer). I guess I got taken, as the service guy did bring in the old filter to me and it looked dirty (he said) then I read tonight that it's supposed to be gray on one side! But it did look dirty, and the old service records which I have, don't mention it ever being changed.
I did use synthetic oil, and paid to have the tires rotated (convenience since I was there and I work), so I had a hefty little bill. (Filter alone was 48$ plus labor to put it on.)
Just paranoid about my car not getting the right stuff at the right time. And I am not wealthy so it needs to last a long time.
For the person who asked for pics, I don't have a digital camera yet and not savvy about pics on the computer.
But I really value the info I read on this forum. Haven't posted much, but I read lots!!
