Not market related, but useful if true:

The overly long article makes the case that:

1. It is severe overkill to be changing your oil every 3,000 miles. 5,000 may even be more frequent than necessary–try 7,500.

2. If you use Mobil 1 Extended Performance synthetic oil, you can stretch it out to 15,000 miles.

3. Not included in the article, but I recall a big study by Consumer Reports that came to roughly the same conclusion. The experiment was done on NYC taxi cabs (iirc).

I hate changing oil and had been thinking of how great it would be to have a Tesla for that reason. But I could live with once every 15,000 miles.

I think you can make an analogy here with time, risk, and energy spent on unnecessary trades that among other things, don't meet certain criteria, are part of a preset dogma that doesn't take advantage of market price movements, use of energy, capital, etc. that could be used for other activities, etc.

    You can send used oil samples to Blackstone Labs for analysis to determine precisely how well the oil performed. Why guess when you can look at the facts?
