 My Nissan is a Gas Hog.  I am getting 
13 miles per gallon,in the winter, and 
15 in the summer.  I know why the 
differnce form weather to summer is the 
cold, and no my foot is not to the 
floor.   But this kind of mileage is 
very very very poor.   I live in the 
north and we have bad winter,  I had to 
get snow tire because nissan put summer 
tires on a 4x4 truck(how dumb). I wish 
nissan would do somthing with the 
frontier.  with out the supercharger 
they are the weakest small truck out 
there.  I had a Toyota Tacoma with the 
v6 and was getting 19 to 20 year 
round.  I should have kept my Toy.
