dang. 23.6 mpg on a 235 mile trip to
Tipsoo Lake since cleaning the MAF sensor, replacing the air filter and "resetting" the EFI. I haven't been able to find anything about the EFI reset procedure in the FSM, so it fits in the category of "black magic" for now. Stumped around in the snow for awhile and took pix of a wee part of our little planet with my tired and sand-scratched old phone (it's an antique). got home and dumped 8.3 oz of Seafoam in the crankcase oil, pre-oil change and the rest in the tank with fill-up. I weighed the 8.3 oz out. The remaining was 5 oz. All this from a can said to contain 16 oz. muy suspicioso! Anyway, it was a two-pack of 16 oz cans, so what went into the fuel tank was probably somewhere between 21 and 18 oz. It's supposed to be 1 oz per gallon of fuel. Whatever. I'm sure the Seafoam people would be delighted if I put 18.5 gal of Seafoam in my tank, and I suspect the T4R would probably not complain too much. Snake oil? We'll see.
