I average 15-17MPG, I could get that out of an F-250 Turbo Diesel. Direct injection technology makes engines ever more efficient. A 2007 V8 is more fuel efficient than a 2000 V6. The 4Runner is a bit of a turd in the engine department.

 

It was tough selling my 98 4runner and with all the mods took about 8 months. So if you've got time, someone will come along. Sweet Tundra!

 

Ehhh.. I donno about that. But, check the fueleconomy.gov website, they have actual data from people. I really cannot see how a V-8 could physically get more fuel economy than a V-6.

My dad has a 2003 V-8 2wd Tundra. He gets 15 mpg max, and its stock. I get 17 mpg and I have 35's!

I'm not talking about diesels, they are much more efficient.... problem with them is the emissions. I forget, but doesn't a gasoline engine work at about 30% efficiency and a diesel is like 40-50%... less heat is being lost into the atmosphere and used for actual engine power. Pretty cool stuff. Im learning about heat engines right now in my engineering class, I'll get back to you on that one

 

I think it has everthing to do with gearing, the new tundra has a 6 speed. My father-in-law has one and cruising down the freeway at 70mph the tach is at 1800 RPMs
We recorded avg 16mpg with a best tank of 18mpg from Tucson to LA and back.
