This is great so far.

Here's how it's shaping up so far:

GenI 3.0
20.3 manual
19.2 unknown
15.5 auto
20.? unknown

GenI 2.6
12.2 manual
12.1 manual
22.? auto
16.? manual
13.? manual
15.? manual

GenI 4.3
20.5 auto

GenII 3.5
16.? auto?

GenII 3.0
18.7 manual?

So far it looks like the EFI trucks are getting much better fuel ecomony.

I'm a little suprised that the smaller, lighter trucks with smaller engine are doing so poorly. I have to wonder if this is an accurate trend or if this is only because the only rigs posted have problems.

Please keep posting your results. Be sure to include actual miles and actual gallons used. Accuracy is key.

And keep posting even if you already have. We're looking for patterns here (and it's something the government didn't look at when they did their testing). <img src="/forums/images/graemlins/wink.gif" alt="" />
