hmmm... sobrang drastic naman ng fuel consumption...

when I was using SeaOil's E10 before, halos pareho lang ang fuel consumption ko.

Tama M2 sobra ganitong fuel consumption difference. I just wanted to impart that E10 has less energy compared to pure unleaded. You may not even notice the difference in consumption or acceleration/power.

Alcohol will raise the octane rating of gasoline, but at the expense of fuel economy. I've seen both ethanol and methanol used to dilute gasoline. Ethanol used to be employed in concentrations as high as 10 percent to formulate oxygenated fuel. ......as high as 0.3 percent are acceptable, and specifically permitted by most of the car manufacturers. Higher concentrations in vehicles not designed for alcohol can cause corrosion of metal parts wetted by fuel--things like the inside of the tank and the lines, and the pintle valve in the injectors. High concentrations of alcohol also can make non-alcohol-rated plastic parts turn to Jell-O in a few months.
