[101Volts]

Though I retired Moony from fuel logs here, I thought this was worth posting as it's the highest MPG tank I recorded so far. (I say "So far" since I'm not sure if I'll take it out of retirement or not.) Here it is, Straight from the fuel logs though with some unnecessary-to-post parts left out and a few parts changed while remaining relevant and true:

2013-October-18
359.8 miles/579.04 kilometers
12.598 gal (US)/10.49 gal (Imp)
47.69 L
424.55 kWh
Gas Cost: $3.309 ($41.69 total for this fill)
28.56 mpg (US)
34.3 mpg (Imp)
8.24 L/100 km
3.5 gal (US)/100 mi
1179.96 Wh/mi

"Fillup #14: At the tail end of a long trip. I drove for all of this tank except when my Father drove down the driveway this morning. About 346 of these miles were today and most were highway miles. For about 13 miles (On the previous day) the van wasn't loaded, For about 170 miles we had it loaded to Ohio with a telescope and the rest was loaded heavier to the gas station."

I don't recall the pressure the tires were at - 55 Hot or thereabouts? The roof-rack was also removed and we had plastic (or the pizza pans?) on the hubcaps along with tape on the wheel wells if I recall it properly, but I recommend using something other than duct tape since when I removed it I also removed part of the finish and ended up with a rust hole that was later filled. Also, At the time there were still parts that I think hadn't been replaced ever such as the spark plug wires and fuel filter.

So, There you go.

EDIT - Note, the middle and rear seats were removed for this tank.
