OK to be more accurate the loss of one mile per gallon was constant across
five fillups. I expected the first one or two tankfulls to be off but the
computer did not compensate even after the fifth one.

My bottom line is that a replacement of the t-stat alone may not be as
beneficial as replacing it along with some performance upgrades. Also, if
you get pinging under hard acceleration then forget about the gas mileage
and run the engine cooler.
