Just bought a quart of Redline 75W85 GL-5 for the PTU and a quart of MT-LV 70W/75W GL-4 for the RDU. Planning on doing the first fluid changes on the 2024 ST somewhere between 10-15K. I know this is a bit early, but after all the horror stories, seems like a good idea. Peace of mind too.
"Sometimes..."? I think most times. The search functionality on these forums is just not very good. Not just this forum, but almost all forums I visit. I have never had much luck finding anything on any of the forums I am on. But your advice about using Google is spot on. It even sometimes brings you to the very thread in a forum you were trying to find! Very frustrating.
That is usefully info. I commented on engine oil but that is different. The fluid that came out of the ptu at 158k was absolutely burnt. It is amazing the thing drove in a parking lot up till 168k. It may have been the longest lasting ptu ever. It was very noisy but no metal fragments in the case. When they say it is a regular drain and fill, that is no joke, 30k, in my estimate.
