Low temp thermostats....

[Sputter]

Out of curiosity. Did you find that oil consumption increased with the lower t-stat?

No, we have not seen any increase in oil consumption with the LN stat; and (in fact) if anything would expect that we would see consumption decrease with lower operating temps, not an increase........................

Why I asked is because with lower temps you might see lower engine tolerances due to lack of expansion. (though at that temp difference it may mean nothing).

Oil consumption would decrease with the low temperature thermostat, if nothing at all, because the oil will be cooler, thus more viscous.

This is akin to the difference between running 0w40 m1 and 15w50mi in an aircooled 911 - a change as little as that has a huge affect on oil consumption, with the thicker oil using significantly less. My 964 would use 1 qt/700 mi with 0w40 and uses 1 qt/1500-2000 mi with 15w50 m1, for example.
