To dig up an old thread............
Is anyone using Liberty E10??? its quoted at 95 octane. I use it in my shitbox 4wd and its OK. But I haven't used in the Line yet and generally always reach for the 98 - but its like 20-30 cents/litre dearer. And before everyone says go E85, I can't, the servo is in a neighbouring town, not in mine. But I do know that Caltex also sells an E10 but it has no octane label and I haven't really checked it out.
BTW I searched and this was the newest thread I could find on the topic.
