Mga tsikoters, I have been using E10 on my 1993 Corolla XE 1.3L carb engine since Its introduction in the market with no problem. Since the car is already old I replaced all rubber fuel hoses with a new one from fuel tank to carburator. Hatak is ok with Shell E10 and mas ok sa Petron E10 considering its 95 octane rating. FC also improve a little bit . Hinataw ko sa skyway up to 120KPH ok naman.
