15.5 mpg - How can I improve this?

4765 Views 20 Replies 8 Participants Last post by  AtlanticBlue99
I recently calculated my mileage for my 2001 v6 (stock, no mods). 15.5 seems way too low.

All of my driving is local streets (school, sports, parties, etc), but it still shouldn't be that low I think?

Is this normal, or is there something I should check for? How can I improve my MPG?

I will look into the seafoam, and have read some pretty positive reviews and even tutorials on how to do it. Thanks for the suggestion guys!

how did you calculate you MPG? by pump or by what your gauge read?
and yes a tune up will help you save gas
I set the trip a week ago when I last filled up, and when I filled up today divided the trip by how much gallons of gas the pump said it put in.
ohh yeah that's another thing bad o2 sensors really **** up the mpg's
Is there any way I can test to see if they are bad, or should I just assume so?
