Good God, Ya'all!!!
8 mpg?! I've never seen THAT low, even with my 4.6L 4x4 SCAB in pure city driving. ...Even with my "leave it idling while I wander around and talk to people" wife driving I've never seen that bad of mpg. The worst I ever saw was while slow 4x4 and letting it idle some in the woods, 10 mpg. I usually get 15-16 mixed and as good as 20 mpg if the traffic cooperates on the highway. Maybe I'm just lucky...

This is why proper service, including the transmission is critical. I'm sure the OP's issues with mileage were primarily related to the transmission. I'll advise everyone to be careful with engine flushes. If you are using a good oil at proper intervals there should be no need for additives. If the motor is varnished/neglected there are a few additives that don't harm lubricity or seals, but there are many more that harm lubricity. Be smart about additives.
