MPG loss at the expensive of a LONGER life transmission
gas is cheap you would only lose like 1% while extending the life of the transmission for many many extra miles
mine runs between 145F-165F winter/summer those are the ideal temps if you want the transmission to last 300,000-400,000 miles
once you get into the 190-210F range it will last about 115-150k miles
