GrassHopper, how fast do you normally drive on highway? During highway driving speed can make more of a difference than a little extra weight.53k miles 90% highway, so far avg 18.6 on the 136WB. lots of times I'm loaded with more than a 1000lb
Ollie, there is something wrong for sure. I got my PM last January while it was really cold. Drove maybe 1,500 miles in cold temperature in City/Hwy mixed mode and I got an average of 13.9L/100 km, that is 17 mpg.136 LR i am getting between 9-10 mpg suburbs/city driving , when cold below 20F , used to get 16.5 in the summer.
I drive usually 65-75mph on the highway, I cover all kinds of land, Pennsylvania Appalachian mountain to chattanoogas mountains to rocky mountains to flat lands of indiana and Ohio, Michigan and Illinois. I sometimes got more than 3000lb in the back, that makes the PM stick to the road like glue.GrassHopper, how fast do you normally drive on highway?

Also wondering if most of that 90% highway is flat, hills, or mountains? In other words which part of the country? Or does it make much of a difference with your van if you've covered all terrain?
