Should call that out in your owners manual. Everyone has a different opinion on this, as well. Personally, I believe by 1500 miles the vehicle is pretty well there, I consider it done by the first regular oil change.

Yeah I think the engine is "broken in" fairly quickly but your mileage may continue to improve even up to 10,000 miles. After 10K though, your mileage is pretty much carved in stone.
Be sure to check tire pressure; also, if you regularly drive at over 70 mph, you aren't going to get the advertised MPG.

Missouri has required 10% Ethanol in all grades since January 2008, although some gas stations were offering it in at least one grade a couple of years before the mandate kicked it. I've seen a noticeable (~3 MPG) drop in mileage on my 2004 Isuzu Axiom since then. So I'm wondering if direct injection engines are more sensitive to E10 than other engine types.

Sorry to change the conversation, however my casual reading tells me that Ethanol in all grades is the least efficient bio-fuel thus far tested, and is in direct competition with humans for a ready available food source. Ethanol as fuel source should be removed our Lexicon. One day we all will regret the use of corn in this way.

2002 to 2006 Acura MDX - regular gas ok?

I believe Acura recommeds premium gasoline for the MDX.
However, I would like to use regular gasoline.
I need feedback form other owners who are doing this or may haev done this in the past. Any degradation in engine performance or pinging?
Thanks!

While it is unlikely that your engine will ping, it fairly certain that both performance and fuel economy will suffer. Long story short, it will cost you less to use premium fuel in the car.
