I know the original post is over a year old but in case any new member is looking at this. My average fill up is right around 9 to 9.5 gals if I fill up when my light comes on. The car has an 11.9 gal tank, which means that I would usually have about 2.4 to 2.9 gals left. So depending on time of year (temp) or driving habits I can go an additional 80 to 150 miles. I have only had my CT through mostly winter months where I was only avg 37 mpg's but my last couple of fill ups have gone up to 44+. Hoping they keep going up as it warms up.
