I have not seen a lot of people modifying vans in the group (understandibly) so I wanted to post some of my own test data for others to have access to.

I have a 2012 Dodge Grand Carvan with the 3.6l Pentastar V6. It has 93k miles on it. I just replaced the spark plugs / air filter / engine oil. I took it on a 240 mile trip last weekend and averaged 26.44 mpg per my scanguage 3. The engine temperature hovered around 170 degrees F with outdoor temps in the mid 50's. With this information, it appears I am safe to experiement with grill blocks. For some quick/cheap trials, I purchased some clear vinyl to experiment with. I am going on a simlilar trip this coming weekend, and will update with my results. Pic below for reference.
