Maybe in the summer months you could use 10W40(if you want to get rid of some in your stash) but, don't go out and buy it specificly to run in the summer. Todays oils are very robust with good addative packages. 5W30 or 10W30 year around is fine in a Honda.
I don't use 10W40 anymore although I may buy a stragler qt(s) on a discount shelf, CHEAP... And, the only time I even use 10W30(yes, 10W30) in a Honda or any of my newer vehicles, is because that's all thats remaining on the shelves when I finaly get to take advantage of the sale price and even then I'll only use it in the summer months. For the most part, 5W30 is what I use in my vehicles unless they call for something else.
