-I think the best idea, is to change the oil whenever we feel like it, regardless of the
manual recommending 10,000 miles. I mean seriously, who do a whole crew of Japanese engineers think they are writing this nonsense?
Seriously though... Here's a good one. So I'm in PepBoys, and I see a little display that has some interlocked wheels on two sides. There's oil in the bottom of the display and two places to turn the wheels. The idea is, on the left is untreated oil, and the right has a oil sample with some nonsense additive added. The right is slighty more viscous, obviously making it better... Yeah. Better.
Sorry for having to be such a wise-***.
