Yeah that's pretty much normal. I get exactly 20 on the highway and noticeably less for just city type driving.

i think he might mean early model SC300s because those have been notorious for being worse than SC400s on gas.

I average 17.3-17.7 in my SC400. I bet with tune up it would reach into the 18s.

Hmm...I have '95 SC300 and I get about 21 mpg average when city and highway driving are combined...So that'll roughly translate to 18 mpg in the city and about 22 in the highway seperately...I can get about 390 miles before the reserve tank kicks in. Not bad huh?

Right now, my trip computer says I average 21.3 MPG. Try pumping up your tires to 40+ psi. Ever since I started keeping mine at 45 psi, my highway MPG has jumped from 21 to about 25 MPG, plus the car feels much more agile and responsive. If I obeyed the speed limit, I'd probably average a couple more MPG.
