Logging oil changes

On my 172, I have an O-300D with the larger engine access door. I write the
hours and date on the oil filter when it was changed - that way, each time I
open the access door, I'm reminded of the time for next oil change.

I do log oil changes, otherwise I wouldn't know when to do the next 25 hr
or 6 month change. Also, I want to have a good maintenance record in case
I decide to sell the airplane.

As some of you know, I'm in the market for an airplane. To this
endeavor, I
find myself reading through a lot of maintenance log books.

I've noticed that some people log oil changes but some do not.

I'm a little worried about the owners who don't because I don't know if
the
oil is ever changes or not. (Yes, I know that it just being in the log
book
doesn't mean it is actually done, but it does a lot to put my mind to
rest.)
All the owners I've talked to claim that they do oil changes in 25 or 50
hour intervals, but they don't log it.

Do you log oil changes?
