Now, if you put in some 85 octane like they have in places in the northeast, they may have a point....

You've got to understand that generally speaking, owners manuals say "use 87 octane", which really means use "regular". In most parts of the country, 87 is regular. However, places like CO, UT, etc. where we're at a much higher elevation, 85 is the norm. Every single vehicle I've owned has said to use 87 in the manual, but 85 is fine. I wish they'd just put in "use regular."
My parents have used 85 for as long as they've owned their MDX (premium recommended). Still runs great like it did on the day they bought it new, and it now has over 120k miles. 23 MPG on the highway.
