I've been doing it for a long time. Nothing easier or better.
I even note wee things like bulb replacements because:
a) as mentioned above, it's good to see if trends appear. It's how I was alerted to the weak connections for my headlights. They ran red hot and ate H7 bulbs. No more.
b) it marks a date and mileage point if nothing else.
Most recently I was able to see how many miles I got out of a pair of tires a friend gave me.
30,000 miles on 2 used Cooper CS4's mounted on a Harbor Freight mounter and balanced for $5 each was worth it.
I could go on......I think I will.
Keeping records is how I know my "big deal" Bridgestone Turanza with Serenity tires-that's 80,000 mile rated Bridgestones-lasted only 51,000 miles with religious rotation and pressure monitoring.
They wore evenly.
The conclusion I arrived at was that tire companies, because they get to employ different meanings to words, get to lie like rugs.
Somehow the 80,000 mile rated "touring tires" I bought magically became "performance tires" when I mentioned it to my dealer.
