Hey Rich... Welcome. You can only get better by reading web sites like GH.
Also try

if you have not done so already.
I feel I'm a "seasoned" Escape Hybrid driver, and I'm getting about 37 MPG to 40 MPG on a regular basis... in a 2WD model... now that I 'think' I know what I am doing!
I started out at about 33 MPG, so if I can improve about 5 MPG with simple tricks, you can too! What have you tried so far?
I must say, putting 44psi in all 4 tires is the easiest way to get better mileage.
There are about 10 things you can do to help in a cumulative way.
Tell me more about your situation, and I'll try to help. You can send me a private message if you wish not to post.
Good Luck!
