You know, I started reading this post before seeing who wrote it, and could instantly figure it out. I mean that as the highest of compliments, Stan! Another great tech tidbit, thank you very much for the info!
I have a general question about oil filters and warranties. I know I can do oil changes myself and not invalidate the warranty, but do manufacturers typically require that OEM parts be used? It seems like a logical thing for them to request, as there are proven differences between effectiveness of various oil filters. Perhaps a better way of phrasing that would be, *can* a manufacturer deny warranty repair work on engine internals if a non-OEM oil filter were used? I am a little reluctant to mess with anything on this engine until I see that there's no oil starvation problem with this motor in this application (to recap for those new to this subject, the early 2ZZGE motors in the Celica had an oil starvation problem under high cornering loads, but this has supposedly been fixed well before the introduction of the Elise).
