It may not seem like much, but when you do close to 50k miles a year, the savings are enormous!

9 MPG = 11.1x Gallons per hundred miles
12 MPG = 8.5 Gallons per hundred miles
Per thousand:
9 MPG = 111.x Gallons per 1k
12 MPG = 85 Gallons per 1k
And ten thousand:
9 = 1,11x Gallons per 10k
12 = 850 Gallons per 10k
Yep.
