In warm weather I've made it to 170 miles. However, in cold weather I'm lucky to make 70. This is the result of having a bladder in the tank.
Im only on my second tank but do wonder if the gauge is anything like accurate. It seems to take a long time to move to the second pip but after that it goes quicker.
my previous car was like that. I would drive for about 80 - 100 miles before the needle would get down below the F. After that every quarter of the tank took about 100 miles.
