expect a small decrease in fuel efficiency though, if you go exclusive on e10. carbs mix air n fuel in the carburettor, less efficient than fuel injected engines. i think fuel is lost in this mixing process from evaporation... and we know how ethanol evaporates more quickly...
Tama si Sir Volts, that is why it is generally recommended for fuel injected Engines, i think medyo palyado ung takbo mo nyan at medyo magiging maingay ung makina mo. Maganda ung sa Petron na E10 95octane sya mix mo na lang ng Extra Unleaded nila 50/50 pra hndi masyado ramdam ung pagbabago.
