I’ve now done one and a half commutes using my new motoring strategy: on all flat pieces of road and going up hills I maintain 70mph or about 3000 rpm, and going down hills I’ll go faster but not so fast that the it feels like I am hurting the fuel consumption. If I turn the OBC to current mpg and notice that it is less than the average then I ease off.
So, the results… trip one started with a little city driving, then to Brawley and back to San Diego, got my best mpg yet – 26.9 (OBC said 28.1). Trip two started just outside El Cajon on the freeway to Brawley and the OBC currently reads 31.3 so I am hopeful of a 28 or 29 mpg. I’m impressed with the results and doing 70 ain’t so bad.
