I'm talking identical. I mean identical, like straight from the factory virgins. I just have a feeling that there is no consistency from one 1NZFE to the next rolling off the assembly line. I'm probably totally whack, but after 11 years on here, reading all the economy stories, that is my conclusion.

Ah, yes that could very well be true. I remember when the Yaris first came out, the guys on the hypermiler forums were reporting 60mpg with their runs and made fun of people trying to get $7000 for a 15 year old Civic VX which does about the same mpg. I guess that's where my rant originally came from for the Yaris economy figures I've been getting.

I used to drive a Civic HX which was the newer upgraded model from the Civic VX and although the mpg rated numbers were pretty high, I was getting about the same mpg figures as my current Yaris. I like the fact that the Yaris feels like it has much more torque than both the Civic VX and HX though, I can actually peel out with the Yaris easily which didn't seem possible with the civics. Then again those civics only opened up one intake valve on all 4 cylinders and later opened all 8 when you reached 2000 rpm. It's also possible the bad mpg on my old HX never had the EGR and throttle body cleaned, nor the oxygen sensor / air fuel sensor replaced which I hear makes a big difference.

This brings me to another question, is there an EGR valve on our cars? The only thing I've read on this forum was a way to clean the MAF sensor but nothing comes up when I search for EGR cleaning or emissions related cleaning.
