6.5 TD Highway Mileage Poll by GMC Hauler

[GMC Hauler]

Did I miss something, but what is or when are we going to see some results?

You havent. I was hoping to get 20 responses before I put something out. I have most of the data computed. I'll give it another week. If I cant get the desired responses, i'll put out some info.

In the meanwhile, everyone that hasn't posted, please post.
