I think everyone is switching to summer gasoline as well, so that helps some too. winter gas isn't as potent as summer gas because of the additives and things they put in it. Good to know the mileage is increasing
I know that i don't worry much about the coolant overheating because my mechanical fan keeps it under 200, and I've never been able to get it over 200, even while high rpm mudding sessions, but I do care about oil overheating. i monitor this by oil pressure. once when I had a full car, load and full grille block and driving at 65 and city driving, my oil pressure went down into the low teens and made the engine run really rough. then the lower block fell off somewhere and it's been good ever since. normal oil pressure is between 40-60 in my vehicle, and it's ok to be in the 20's if you've been hauling or doing heavy accelerations, but low teens isn't good.

What do you drive mostly? highway or city?
cerdmier, if you drive mostly highway, you could probably get by with blocking the top one, which you have done already, and the big bottom one between the two "teeth" looking pillars. Just leave the two side ones open, and combined they make about half of the big bottom one. that should be a big enough opening for cooling.
