Guys, need your opinion. I usually drive my spark 1.2lt at 50m/h(80km/h)5th gear at a distance between 50-100km driving which is somewhat im happy coz the engine does'nt sound stressed (its about 2,100-2,200rpm accdg to the stock tachometer) but i do want to give the pedal to 60m/h(100km/h) but im worrying if the engine can't take that 3,000rpm for a long 2-3hrs steady. I need ypur opinion.. Thanks!
