I know there are endless online discussions about this topic. From what I'm reading, 87 is perfectly fine, given all the sensors and computer-aided timing, but to get maximum performance and efficiency 91 is recommended. Does anybody disagree?
What I also don't understand is the Honda Pilot has identical compression ratios, and only requires 87. Are there other elements of the engine that are benefiting from 91? Thanks!
