Oil condition sensing on new Hondas

My daughter's new FIT seems to "sense" oil condition, rather than depend on miles driven. That's clever, if it's true. Is it?

The oil condition is not sensed directly. The engine computer monitors total revolutions, temperatures and other factors to arrive at an aging curve for the oil. It is much more sophisticated then the old xxx miles/yyy months way of doing things.
GM of all companies has been a leader in this kind of technology, but many of the Germans and now Honda are also taking up this methodology.
Assuming that Honda's engineers did their homework correctly it should work out well. If you want a little extra safety factor you could do the oil change early, say at 20-30% of indicated oil life remaining instead of going until the car insists that it is time.
The new way is much improved over the old rules-of-thumb.

haven't aircraft engines been done like this forever?
it occurs to me that hybrid cars might need to do this, too, since the internal combustion engine might not even be going, for some significant number of miles / hours.

Has anyone had the used oil tested to see how consistent the oil change indicator is?

There have been a few postings on the www.bobistheoilguy.com used oil analysis forums where people have gone the distance and had an analysis done. Not many though as most obsessive compulsive oil gear heads are not able to wait that long!

basically the new hondas have a thing called the "maintainence minder" which does calculation based on engine temp and revolutions of the engine to determine the oil life (pretty much, if you drive hard it wil lower nquick, if you drive easy it will go down slower) My accord was first changed at about 5000 miles (the computer said 10% oil life left) I currently have 8000 miles on her and it says I have 40% left.

It's in the manual. I just changed the oil on my sons 2006 EX-V6, and it was simple, though I don't have the manual handy now.

From Page 170-171 in your Owner's Manual: 1) Turn the ignition switch to the ON (II) position. 2) Press the Select/Reset knob repeatedly until the engine oil life is displayed. 3) Press the Select/Reset knob for about 10 seconds. The engine oil life and the maintenance item code(s) will blink. 4) Press the Select/Reset knob for another 5 seconds. The maintenance item code(s) will disappear, and the engine oil life will reset to "100".
I know the manual isn't exactly the latest Michael Crichton novel, but it's still worth reading.

Thanks, I guess I should have read the manual instead of the quick guide. It says the dealer resets it when servicing. I changed my daughter's 05 civic oil twice and never reset the meter. Should I wait till it blinks to change?(any thoughts welcome) I am old school oil and filter 2000-3000 miles. My wife has a 06 pilot with the oil life indicator, no problem yet only 2500 on it. Carl
