Woohoo! Broke 80 mpg... barely ... for my summer tank!
(
blackfly fuel log)
Also, I cracked 1000 km for the first time (legitimately), and could have gone a lot farther (put 32 litres into a 40 litre tank).
FYI, this was 100% highway trips (with sub/urban stuff on each end). The first part of the tank would have been P&G, but by the second half, I had decided to mostly just drive with load, and keep working on the aero mods.
Also, the alternator was disabled for about 1/3 of the distance (end of the tank).
I don't have SG data for tank avg speed, etc, because I loaned it out partway through my tank (so it messed up my data).
