Man, that sucks. We just ran our first tank through on our 08 Rav4 V-6 2wd and it came out to 24 mpg. Driving mostly 2 lane hwy at 60mph and the other half Interstate at 70mph for a total of 300 miles.I just bought a near perfect used 2006, 14K, 6cylinder, 2WD, and got 21.5 on the 300 mile trip home at 70 mph.
I love the car and didn't really think I needed the 6, but got a good deal ....... maybe. I'm VERY disappointed with MPG.
My GMC Envoy does as well.
