Today the temperature was at 100 + most of the day, My bike, an 09 C 14 has been covered up for about 2 weeks because of the heat so I decided to take it out for a ride. Some freeway riding but mostly mountain twisty roads, total was 202 miles on my odometer. The AVERAGE was showing 48.5 and of course I thought that was wrong because I never got over 42 MPG. When I filled it up it took 4.16 gls to go 202 miles, thats equals 48.55 mpg. I guess it likes running in hot weather. The temp was showing 3 bars most of the day. Coolant is full and the bike only has 8500 miles on it.
