[s-cars] cooling problem and question

[Twobro12 at aol.com]

Hey, 
I have some questions/concerns about my engine temperature.  

I drive my car everyday and usually use it in durations extending over 20 
minutes at one time.  Strangely, my water temperature gauge continues to read 
cold (sitting on righter most cold black bar) and never moves past that.  Also I 
live in Boston so i wanted to know if anyone else in the area is experiencing 
this or if its my car

Is this normal or do I have a cooling problem?  
Could my engine be warm but my water temp. gauge off?  
oil also reads around 60 degrees C but I don't know much about oil temp (oil 
pressure is normal though).  And also, I've been getting only about 255 miles 
per tank, and in this temp. i haven't been able to drive it hard so that seems 
particularly low to me.  any help would be great, thx
