I have "ZERO" self control in that category, so I am lucky to get 10 mpg daily use. Other than mpg, I guess the gear difference would take away from the life of the motor? Yes, no?

I get as much as 24MPG on long distance trips. The only change I saw in gas milege between 4.10's and 4.30's was long distance driving. I drove back and forth to the Georgia races and with 4.10's got 27MPG and 24 MPG with 4.30's but with my daily commute there was no difference. I do drive the car normally and get on it every so often. A lot comes down to driving style.
I don't believe in the whole life of the motor vs gearing, etc... If that was the case my motor would have failed 40K miles ago. Think about it I launch my car on the rev limiter on slicks (just imagine sitting at a stop light holding the gas to the floor and dumping it with zero tire spin), have over 600 passes on the car, 96K miles, 40K with 4.30's and 30K with 4.10's. My car went 12.55 three weeks ago I'd say the motor is running just fine. Seriously these motors can take the abuse you put at them as long as you maintain them properly. During my commute I'm at 2700-3000 most of the way and I put a lot of highway miles on the car.
