I have been reading so much about GC on BITOG that I finally had to try it. Last weekend, I put GC in my 1997 Nissan pickup and it's been great so far. The engine has been running a lot quieter than it did on M1 5W-30. My wife's RX330 is coming up soon for an oil change. I was thinking of using GC rather than M1 5W-30 in it. I searched the UOA section but found no info. Suggestions/opinions?
GC in Lexus RX?

I almost posted the same thing.......we have a little over 24,000 miles on RX330 and I have been running Mobil 1 5W30. It just seems like Mobil 1 and Toyota engines are good match (based upon the UOAs I looked at). I thought I remembered reading how Toyota engines liked a light 30W vice a heavier 30W.
It was a no-brainer for my Audi A4, it LOVES the GC 0W30.

...but of course
I must add my standard caveat however...while I don't think it likely that you would have an oil-related warranty problem (not with the Elixer of Luxurious Lexus Lubrication), you should check your manual. If it calls for a 5W30, 0W30 should pose your service department no concern.
There's certainly nothing wrong with being cautious about one's warranty, but in this situation, I don't think it's much of an issue. As a practical matter, I think that the mfr would have an exceedingly tough time proving, which the mfr must do to sustain a wty denial, that the use of GC led to any engine problem that would not have occurred on 5w-30 or 10w-30. When hot, GC is on the thick side, but still a 30. When cold, it simply flows better than a 5w or 10w oil would. Based upon its basic syn composition, and its known HT/HS vis of 3.6, there won't be any shear issues as there might be from a theoretical mineral 0w-30 (has anyone actually seen a mineral 0w-30?).
