At this milage, Honda recommends:
It's not nessacary to use synthetic, but the 10w-30 is a little heavier than the 5W-20 which can put extra strain on the oil pump. I would recommend going back to the 5w-20 at the next oil change interval, if not sooner.
The above recommendation is straight from Honda. I'd be willing to bet that Honda knows more about Honda engines, than the guy at the parts store who makes $9/hr. Stick with the Honda recommendations if you want the vehicle to last.
As for the oil life- it needs to be reset after each oil change. The vehicle does not recognize when you change the oil, it must be manually reset. Here's the procedure:
Resetting the Engine Oil Life Display Reset the display after completing the required maintenance service. You will see "OIL LIFE 100%" on the information display the next time you turn the ignition switch to the ON (II) position.Reset the maintenance minder as follows:NOTE: Vehicle must be stopped to reset.
Press the select/reset knob for more than 10 seconds The engine oil life and the maintenance item code(s) will blink.
NOTE: If you are resetting the display when the engine oil life is more than 15%, make sure the maintenance items requiring service have been performed before resetting this display.
