Farthest tank yet, it lasted one month! Front right caliper was sticking and smoking, warped disk. replaced at 3/4 empty tank. much better now. Max speed 76.3 mph, min temp 40F, max temp 85F. Miles coasting with engine off are not counted on the odometer, now using GPS for distance. Fuel cutoff button would be good. Larger tires (205/70R15) defiantly have more aero drag but balaced with lower engine rpm. Front wheel fairing wold be good. Replaced front calipers on hf (crx) and took for test drive, boy this car could get great mpg, It has another gear compared to the sc1, engine is missing at part throttle, though, needs work. Used 89 octane on this fill up instead of 87, we'll see next on log entry if any improvement in mpg.
