Of course she sits in a climate controlled garage 99% of the time and I send off samples regularly to monitor for wear particles, ZDDP levels, the presence of water, coolant, or fuel and to watch the TBN value. The latter is 10.6 for Brad Penn right out of the bottle, and I believe it was down to 8.8 when I changed it. And if you're thinking, "gosh, wouldn't it be cheaper to just change the oil more often?" you'd be absolutely right... but not as much fun.
