I have always been very iffy about using E10 in my car (2000 V6 Camry).. there have been a few times i have been at the servo about to fuel up and looked at the E10 and thinking of trying it (just because it was cheaper). I always had thoughts in my mind that E10 fuel could ruin my engine.. glad i trusted my instincts after seeing that pic  

 I wouldnt have tried it without asking my mechanic anyway
