Best C5 Gas mileage

sting66ray · 09-03-2012, 04:37 AM

I'm about to take a 750 or so mile trip with an '03 6-speed all on Interstate. What is the best cruising speed for mileage and the best for the engine?

one that doesn t get you any speeding tickets!! seriously, these cars are very fuel efficient at 70-80 mph.. I go to Atlanta once a year in my convertible , I drive 80mph , and usually average 28mpg...its a 1300 mile round trip ... yours, being a 6 spd, will probably do even better..

Although mine is a C6, it is also a 6-speed and when on a trip I set the cruise control at about the speed limit +5 and routinely get between 30 and 30.5 mpg. On many trips I have gotten over 31 mpg.

I got about 32 mpg going from Oakland to Monterey (mine is auto).

Lost, thats because of the loose nut between the steering wheel and the seat!!

Averaged better than 34mpg on Texas 130 while driving @85mph (2000 auto/coupe)
