E10 Fuel

i did a comparison in our 2002 corolla, a tank full of e10 got me about 400kms. a tank full of 98 premium went for over 500kms and the car ran a lot smoother.

Yeah, well, not really an apples and apples comparison. The Toyota ECU should wind in a lot more advance on the 98, making it a lot more efficient. So, couple with the increased fuel density of 98 (over normal 91) and then the decreased density and energy content both of E10 (compared to normal 91) and it's no surprise you can do 25% better on 98.

Do it again with 91 and E10, the gap will be a lot closer.

I did it with a Toyota Echo hire car in FNQ about 20 years ago (so, same basic ECU tech as the 2002 'Rolla). Shell or BP 91 got nearly 10% better economy than the supermarket brand 91 (which was imported from SE Asia at the time and was probably E10 and was shit compared to Aussie refined juice).
