Wow…$4.57 per gallon! Yikes. Cant imagine how much it must cost to fill up a bigass SUV at that place.
$81 for an Acura MDX (6 cylinder 3.5L engine, and it's really not considered "big")
$65 for an Audi A4 (4 cylinder 1.8T)
Mileage is about the same (mine's slightly worse, especially with the "non-stock modifications" in the later). Of course both take the 91 octane(craptane) they have here in CA. I suppose I could go down to 87 in her car, but it doesn't really make that much of a difference in terms of cost. My car cannot take anything lower than 91, nor would I try. Fortunately, she drives less than 2 miles to work and I drive about 6 miles to work.
