My mpg on my Honda CRV is really bad this tank of gas. I do alot of highway driving, and usually get between 24mpg and 26mpg on a tank of gas. This time, I noticed my numbers quickly plummeted to the 23s then 22s...and now is hovering in the 21s. I haven't really changed my habits on this tank, and I bought from one of the usual places. I've got about 6k on the OD.
Is it possible to get a "bad" tank of gas?
