Absolutely not. I own both cars and I drive civic with utmost care and on hi-octane and still it gives me a max of 8.5km/ltr. Even Honda mechanics say that maximum one can extract from prosmatec is 8.5km/ltr. On the other hand, I drive cruisetronic carefree and it gives me 11km/ltr in city with A/C on, if driven with the same care as civic, and 9.5-10km/ltr if revd like anything
