Every car and setup will yield different results as far as what speed they can achieve before wind resistance overpowers its efficiency. I like 70-75mph. Never showed enough of a difference in Mpg either way for me to justify being the a-hole slowing down traffic.

Same thing happened to me, the cold weather could have some effect on it.

Well I assume/understand that, Teej said there was research showing that every mph over 65 makes you loose 1mpg...making it seem like a universal statement across the board for all cars, which I highly doubt is true.

Was hoping to read whatever research he found is all. Not like it's going to change my driving but I'll read it for curiosity to see where they are trying to come from.

That is where I got the info from. I mean its been said a lot all over the place, but that is one of the legit backed up resources.
