Warmer weather brings improved economy. All of my mods from over the winter are starting to pay off. It was about 70F yesterday, and cruising through rolling hills I was about to get my factory gauge (which is within 1% accurate) up to 102mpg, over the course of a 20 mile +500ft elevation drive.
Warmer weather means I'm having to open up my grille block! I'm now at 100% upper blocked and only about 80% lower blocked, down from almost 100% lower, and I might have to back off a bit further. I ran the heat to keep the radiator fan from kicking in a few times during some particularly long and steep hill climbs, where I was WOT in 4th or even 3rd gear over a period of several minutes.
