The one time I had a VERY long downhill, I used the engine for
braking (as I normally do anyway). This was from Monarch Pass in
Colorado (US Route 50) heading east. The waterboxer engine will use
VERY little fuel when run this way. I easily got 20 mpg on that tank
of gas (normally got about 18 in the lowlands.) 300 miles, 15
gallons...and I overflowed when filling up. :
