I agree with you. I again don’t understand why this is still being discussed. The manual and gas flap are very clear. Best performance with premium, despite your tests. However, in most cases, you won’t notice the difference.It will still be a choice of preference. The MDX is tuned for both 87 and 93 (91 for those states who thinks 93 is overkill). Heck, go for 89 if you want too.
