We checked the car out tonight and the PCV was clogged,anti-freeze was low and air filter was very dirty.He said the dealer changed all that at 30k miles.It now has 45K miles so maybe the dealer didn't change all that stuff after all.Maybe all this will help the oil say a bit cleaner.
Thanks to all for the great tips.

The Dealer, Stealering? No WAY!
I was under the impression that these DOHC timing belted 4 bangers were pretty easy on the oil with no turbo. Little pressure needed to open the 4 valves and if you aren't a mad-hat with the revs, they don't spin much faster than any other below 70MPH anyway. And with nearly four-quart sumps, or four with filter, there's as much oil in the sump as many cars with V-6's now. These little sumps are as much a factor as any other, I bet.
This roller-skate Hyundai I drive doesn't darken the oil even a little in 4000 miles, let along blacken it. I vote bad skinky PCV valve. A quick run of ARX and a new filter ought to clean it up, yes? No?

Sorry for my ignorance, but how often do you change your PCV valves? I neglected mine which is likely the reason for black oil. Although both my engines are small, so probably run hot.

Bob, I change the PCV valve at every air filter change. Lately that has been at the 10,000 mile mark. I think that the older the engine, the more often it should be changed or at least inspected for proper function.

Duh, of course.
Still learnig new things every day. thanks
P.S.: By the time I learn everything I need to know about gas engines we'll go electric

The oil in my honda odyssey was always dark brown after a few hundred miles and all I did was pour seafoam in the crankcase and the oil has been much lighter ever since and its the color of tea when I change it at 7k miles now instead of black like it was when changing oil beforehand.

Try a EAO filter, oil stays noticably cleaner.

I started using the $6 wix 51356 with its beta ratio of 2/20=6/19 instead of continuing with the honda filters so that will help keep it cleaner. Those EAO filters are more expensive correct? The $6 wix 51396 that I use on my corolla does a great job of keeping it clean too, much better than the toyota filters did. It has the same beta ratio as the 51356.

Mine's got 60,000 on it, I haven't changed it, but I've pulled it and made sure it's "breathing", so to speak. I hit it with a spray of brakeclean and re-install it. They really shouldn't go bad unless they sludge and stick. All it really is, is a lightly-sprung check valve after all.

Well they are not that expensive anyway, so I'd rather change.
Actually, I had a [censored] of a time finding it on my older 1995 Civic CX. Seems new cars have them right on top of the engine for easy maintenance. However on my CX I just couldn't find it. I found one or two valves which I am not sure about.
Anyway I'll change it 1st, then take apart the old one to see what is inside. Maybe I can just blow compressed air to clean it.
Why "breakclean" in particular? What about other solvents, or carb cleaner?
