Since the OLM has come into question, I thought I'd post my observations on the OLM built into the '06 Hondas...my car has been exposed to rather cold temps (up to -10F) since I've taken delivery, and I drive it lightly, for mileage, but I also drive a lot of miles (about 3900 in 9 weeks of ownership).


I happened to just catch the first two 10% decreases. The first was at 750mi almost exactly. At that point, I wondered... "will it decrease 10% every 750mi, to show 0% at 7500mi ?" (7500mi is the mileage at which the old system would flash and stay lit as a reminder to change the oil - but it wasn't an 'intelligent' system, the way this one is supposed to be.

As the car approached 1500mi, I kept my eye on the OLM. Right about 1550mi, it dropped from 90% to 80%. I started wondering how 'intelligent' the OLM really was, and figured I'd see the next change at about 2100-2400mi.

70% came along at....2508mi So far, the reductions were looking pretty darned linear to me - every 800mi on average. Temps had been increasing a little bit, but no higher than about 40-45F on average.

A few days ago, the OLM dropped to 60% - at about 3350mi., or about 850mi since the last decrease.

So, to recap:
100 > 90% = 750mi
90 > 80% = 1550mi (800mi elapsed)
80 > 70% = 2508mi (958mi " )
70 > 60% = 3350mi (842mi " )

From what I remember, the following criteria are evaluated to calculate the oil life:
Avg Trip length (shorter depletes oil life % remaining faster)
Avg RPM (higher depletes % faster)
Avg Temperature (lower depletes faster)

Now...given that the 1st 10% came during some of the coldest part of our winter up here... at about 1700mi, initial break-in occurred...an additional break-in at about 2200-2300mi, initial tire tread wore off and decreased rolling resistance somewhere along the line...and it's gotten warmer out in the last few days...

What approximate mileage will the OLM in my car decrease to 50% ? (I'm going with 4000mi, myself)
