Haven't updated in a while!
Started running 89 octane gas in Rawhide, and he liked the first tank. Mileage went from 10.5 to 13.85! Not bad at all for this ol hoss in Houston driving. So... second tank, hopefully as good. Nope! The AC had quit working partway through that one, went back down to 10mpg. Windows down, maybe more idling. So...third tank, first part is still w/ no AC. Second half was after I fixed it (by removing and reinstalling the blower motor, making sure the connectors were both plugged in good, and replacing the HVAC fuse, 25amp). Blower motor makes more noise than I like, but it's 2 days older than the truck. So it'll get replaced by the end of the year, sooner if the funds are available.
So I was hoping to see improvement in the mileage. Nope, got 8 this go round....was there really that much idling?! I'll fill it on Monday and see what this one looks like.... I know there's some idling and low speed operation on this tank, from moving those trailers, and moving the '06 so I could get inside of it and try to clean it out. No pix of that cause it was too hot and I wanted to get back in the shade!
