forget the TB spacer.

keep with the basics and master those. you have a very good list at getting the best MPG possible with your XJ, keep up with those things and you will do fine.

synthetic axle lube really makes that much of a difference?

you may want to consider getting a rear tire carrier for your rig to cut down on the wind resistance.

Get a lift and bigger tires. In all seriousness I was getting like 10-12mpg when my Jeep was stock about two months ago. Since then I have did a 2in BB 30's Surco Roof Rack and I am now getting 14-16 mpg. I plan on doing a tune up in about a week. We will see what happens after that.

that is true, however your spare up top is one of your main reasons for loss in MPG.
