My son just bought a 07 IS250 AWD and I told him I would change his oil as I do with my LS400 and RX330. He is reluctant because of warranty issues, but the dealer says as long as we keep track and use Toyota filters it shouldn't be a problem.If it wasn't for your description and pictures, I would be completely screwed. I wouldn't even know where to find the filter! At $150. for a synthetic change at the lexus dealer, my son is ready for me to take a crack at it. Without your help I wouldn't be able to do it.
My many thanks!
