Well it's early yet, as I said the outdoor temp is not real low. But ya it seems to be gobbling a few less pellets. Now your brush is more efficient than mine, I just use a soft paint brush, so who knows how long that back side crud was on there. The thing is it was kind of tacky crud, sticky. So I used some glass cleaner soaked in a paper towel this time.I would have thought that the ESP would have to have been pretty cruddy to affect temperature.
I have seen some pictures of 1/2" crud on some.........but,
if u end up getting better mileage after cleaning, then you convinced me to Actually remove it once in a while ass opposed to brushing it.
