Towed 2000lbs in 100F heat for the last 1300MI on the oil (95% Highway driving with little traffic). First 1300MI of engine were short trips in the city.
I am not going to freak out over the copper, iron, and aluminum since the engine is breaking in. I plan on leaving the oil in until the OLM tells me to dump it (as per the manual). Will do another analysis then.
code:Honda Odyssey 3.5L V-6 Gasoline Vehicle miles: 2,666 Miles on oil : 2,666 Life of oil : 7 Weeks Lab: Blackstone This is the type of oil used for Honda Factory fills, loaded with an anti-wear compound called molybdenum- disulfide and reading lighit in viscosity from use. We didn’t find anything high enough in this sample to be considered a problem. The highlighted metals typically read high in new Honda engine samples and metals and silicon will drop in the next sample. The TBN was 2.7, still some active additive remaining in the oil. We consider a reading of 1.0 or lower to be too low. The next sample should look better.

Good thing they incorporate micronic filters in the VTEC system.![[Wink]](images/icons/wink.gif){kind=icon}
) , and to tell you the truth I am on the fence about whether to drain early. Part of me says a I should, but the other part believes that there must be a reason that Honda is strongly suggesting I leave it in.
I know this has been beaten to death here, but since I did all that towing I think I might have a unique situation.
The maddening thing is that I know if I call Honda, I'll just get the canned answer from the website or the manual.
Of course my neighbor who works for Honda Racing only made the comment; "Honda generally doesn't make recommendations without any type of science behind them. In the racing division our motto is 'in order to finish first, first you must finish' - you should see the stuff we tear down to make what looks like molecular improvements to engines just to get that cushion of reliability."
Not that Honda production assembly necessarily follows the same motto, but I still can't understand the motivation for Honda to steer me wrong.
My wife thought I lost my mind when I showed my neighbor who works at Honda the UOA last night. I think she’s right.

I'll be sending Terry my oil samples from now on.
