I use sythetic blend and I change it every 3 months or 3k miles. I wonder if I do flushes before draining oil if that's going to help. I used to do that for my Catera since it had some weird problem with coolent leaking into oil. I was just expecting a much superior product from Lexus based on all the reviews. My brothers are very happy with their Avalons from 00, 02 and 05 now no problems with anything at all.
Also I'm seeing something about transmission problems should I be worried about that or not? Mine is 2001 RX300 2WD 45k. Is my model affected by this issue or not? If anyone knows please fill me in on that one. Thanks guys.
