I finally got out on the highway for a 150 mile run at speed. Mostly at speed because the traffic is so bad even on a Saturday afternoon.
Of course strong headwinds had to interrupt a smooth day between traffic jams.
I took the photo just as the Nissan 10.8 gallon tank went dry.
That's 166.8 miles or 15.4 mpg. I don't believe it so I've put exactly 15.9 gallons in the main tank, ran the auxiliary tank dry, and will burn off the 15.9 as a second test.
I may have overfilled the auxiliary tank with the click clack pump so this test will be much more accurate.
The transmission shiftpoints need some tuning as it doesn't downshift without absolutely standing on the loud pedal. No problem as I've still got the vacuum switch sitting right on the doghouse.
