Don't forget to fill your tanks if you have to drive any where on Friday morning! (that prevents water that may be in your tank {from condensation} from getting into your fuel line where it can freeze, expand, and cause a fuel line rupture) The last time it was that cold, I must have seen 20+ cars on the side of the road on the way to RDU that morning! ...and who wants to be stranded in that COLD? 9 degress BRRRRrrrrrrrrrrrrrr!!!!!
Not to mention the gas is more dense the colder it is. The pumps measure volume, so ya get more bang for your buck.
