Would you sacrifice a small amount of your engines life expectancy for a small gain in fuel ecconomy?
I base this on the proposition that manufacturers are willing to accept a (small) increase in engine wear to gain a (small) increase in overall fuel ecconomy.
Gains and losses will of course depend on your areas climatic conditions and the anticipated length of ownership of you vehicle.
