Ken: I still think you have hit on something
here. I would worry about needing pressure relief bypass when oil is cold, cold,
cold, like it starts out on almost any winter day. jofarr
I disagree. I'm using 5W-30, so when it's cold,
cold, cold, the oil still isn't thick, thick, thick :-) Also,
airplane guys are kind to their engines. We crank them, and allow them to
gently warm up before running them hard. This is very different from how
it would be used in the car, which I suspect is why Mazda included the oil
thermostat. The only hassle is waiting for it to get 140 degrees before
takeoff. I see the thermostat as being nice, but not
necessary.
Cheers,
Rusty
