Hi Robby,

The Syncro manual says it holds 18.5 gallons of fuel. Some people report
having a hard time getting it that full. I've traveled 300 miles on a tank a
couple of times, stopping with 2-3 gallons remaining. The other big factor
regarding your economy will be the weight you're carrying.

High altitude will increase your mileage, but decrease the power available.
The sluggishness you notice above 6500' is to be expected. At that altitude
your waterboxer has already lost about 20HP, so it's kinda like powering
your heavy Syncro with an air-cooled engine at sea-level.
