I get 20 to 22 mpg and I drive like an old lady 60 is fast as I go unless passing...aftermarket open air filter is the only upgrade...well my 18" G-Spiders w/225.40.18 at 38 psi may have a little more rolling mass and weight than it's been designed to use but, I have to look good while depleting our fuel supply

GS300 = 350 miles of travel with a full tank of gas tank. Average is 22.5 mpg.
75% highway @ 70mph
25% citydriving
(yes, gas milage isn't as good as I hoped, but safety built into the car compensates it!)

Getting 13.8 mpg in 2000 gs400 city driving. Think I was getting about 20 on hwy going 80mph (which feels like about 50 mph). I have to use cruise control on the highway or things can get ugly quick with speed.....oooooppps am I going 95 mph

Although my 02 GS300 on 22", I get average of 310-320 miles per tank(16-17gal). thats both city 30-40mph & hwy 65-80mph which is about 20mpg.
I think im going to change my gas filter this week end. Hopefully, i consume better gas milleage after..

Honestly for some reason I never really bothered to exactly calculate how many miles I get to the gallon, but I guess you can say my driving is aggressive and tomorrow I will start and see what my final outcome will be in a few days also I travel on the Belt Pkwy and its not always a smooth ride, therefore most of my time is spent in traffic
