Crazy you're getting near the mpg my corolla gets (at speed at 45mph, 45-50mpg, but averages ~40-45mpg).
I'm wondering which method of P&G you use, there seems to be no real standard. I haven't seen too much of a change with my truck, but I'm not EOCing atm.
I had fair success with my corolla P&G, 80% load to say 50mph, then EOC down to 30-35mpg and repeat. Sadly it was an automatic so I had to use the starter.
I'm finding it strange that my truck seems to have a hard time meeting the EPA ratings for highway with me driving, I suspect there must be something going on that is eating up my MPG besides the areo. I have been thinking it is just the cold.
My dad has a T100, I drove it 65mph in warmer weather up and down hills and averaged around 20mpg with a check engine light and leaking intake boot.
Cold start this morning at -4F coolant temp was 1.58gph @ 2200rpm. Driving home at 45mph I was using around 1.8-2.1gph depending on hills etc. Warm idle is 0.33-0.35gph. Side note on this, my corolla idles at 0.33gph warm too).
Thanks for the input so far. and lets see a v6 truck get 40mpg average tank (in the summer of course)!
