You may want to check out "The car care nut" youtube channel. Ahmed, a Toyota master technician and owner of an independent shop created a video in which he explains reasons for thinner synthetic oils. One is an oil pump system that monitors oil pressure and flow. A thicker oil would eventually prevent it from working properly. Lake Speed recommends that having your oil checked is a good idea. I believe that Toyota is the last company in the world that would not thoroughly test oils that they specify. Their reputation may occasionally take a hit for other reasons, but their introduction of 0W-20 synthetic oil, 15 years ago has been cause for premature engine failure. Most youtube channels, including the car care nut show too long oil change intervals as the main culprit for engine failures.I disagree. New government regulations drives requirements for thinner oils. It's a cheap way to make fuel consumption targets. If heavier weight oils were being usurped by light weight oils then heavier weight oils would be disappearing from the mainstream market which they aren't.

I also maintain that if oil analysis at your Supra's drain intervals shows that everything is good, then there's no reason to change whatever oil you are using.
