noob needs help with mileage - only 10 MPG!

Captain Easy,

Thanks for your input.

What I'm most worried about is that the low mileage I'm getting now indicates something very wrong with this car.

I posted this in a earlier reply, but I almost got a Subaru wagon, but just couldn't get excited about it. I really do want this Valiant, and I'm motivated to learn how to do things like valve adjustment.
