I have 40psi in my front tires....and they wear even. The rears are 38psi, same wear pattern.

The reason for different front/rear is that the front of the car weighs more than the rear, and needs more air to hold it up.

I get 19mpg on the highway doing 90mph with s/c......

Also might not be a bad idea to run some STP Fuel system cleaner through your next rank, and try buy name brand gasoline. But dont buy any more octane than you need.

So I filled my tank and drove it until the Low Fuel sign came on, that's 13gallons, right?

I drove 220.

That's 17mpg.

My engine is right at 30k miles, should i get a tuneup?

How much do those cost?

To me, this is the hardest things to do in order to increase gas mileage. I think you should try it out though. Don't drive it hard. lol

Fill it up with gas, and the pump will tell you how much gas that is. Fuel gauges are not accurate by any stretch of any imagination.

To get a real MPG reading you have to fill the tank at the same pump.All gas pumps are not created equal.
It doesn't matter what the gas guage says.
Fill the tank as full as you can get it.
Drive the car for awhile,as uniformly and aslight footed as you can.
Go back to the same pump and refill the tank to the same level you did the first time.
Now do the math.
Fifteen to seventeenMPG in town is about right as far as I can tell.It really doesn't make that much difference whether the engine has six cylinders or eight.Eight cylinders just allow you to burn more gas but if you drive both engines the same way it really won't matter that much.It takes the same amount of energy to move the car at any given speed regardless of the amount of cylinders.
For a real close figure try driving the car at a constant speed as close to fifty five mph for as long as you can.I can get thirty two honest MPG at a nearly constant fifty five mph out of my 04 GT 5 spd.This is granny driving at it's finest and every hard take-off drops the miles per gallon by about one per tankfull.
