FUEL TANK All 60.5 L (16.0 gal.)

 

I just took my '02 r/t on a trip from delray beach fl. to Orlando, approx 2.5 hour drive (I have a very heavy foot) and I got 35 mpg there and back, all highway, mostly around 90-100 mph. I have a cold air intake, catback exhaust, and a bored throttle body if that makes any difference. Driving to and from work I get about 25 mpg, and I drive like an A'hole most of the time. my cars pushing 100k miles to, so i'm pretty happy with this little 3.0l v6. Oh yeah, As soon as I stop blowing money the nos tank will go on and I'll let you know how that goes. hurray for engine upgrades on a piggy car!

 

I know I get 28-29 miles per gallon, with combined highway and city,in my Stratus Coupe 2.4L. Of course the 2.4L in the coupe is different than the Sedan, but I am pretty sure your miles per gallon should be pretty close.
