What Octane does everyone use?
I know Acura recommends 91 or higher but is it just a performance issue or will the engine be damaged by lower octane?
If it's an issue of damage, will the engine last longer if you put in 94 Octane?

This has been discussed ad nauseum on the acuramdx.org as well. It seems everyone (or at least a lot of folks) want to buy a sport luxury sedan (or luxury SUV) and then scrimp on gas. Go figure.
The manual clearly states that less than 91 octane can be used but with a loss of performance and/or mileage.
I buy Shell 93 Octane 99% of the time. With the Shell M/C discount of 5%, Shell gas is the best deal in my area.

Cheveron 92.. however, I do fill up the tahink with 94 twice, and it seems I get about 50KM less for a tank of gas.... though I do notice that the engine doesn't shake/vibrate as much during morning starts....

According to Road & Track (Sept 2001 issue)...
"If it says premium, then engineers have calibrated the engine management to exploit this fuel's higher octane. True, if the engine is knock-sensor-equipped, lower octane fuel won't hurt it; it'll just run less efficiently, both in terms of power and economy.
If the the owner's manual recommends regular - and the engine exhibits no noticeable ping - then there's no benefit whatsoever in using a higher-octane fuel. No more power. No better economy."

Recently took a trip to Lubbock, TX
On a recent trip to Lubbock in my MDX (which also requires 91) I was shocked to see how low the premium octanes were.
Shell's three grades were: 86/88/90
Some other stations had: 86/88/91
But there was nothing to be had above 91. Kind of a culture shock for me. There is no problem getting 93 in Houston.
