Running straight ULP it used to get all sorts of cr@p build up on the plugs but with Ethanol fuel it was always clean as a whistle. The denatured Ethanol (basically metho) cleans the combustion chambers, so there is no hot-spot buildup to make it ping.

This is of course back when E10 sold by Bogas was good stuff, sometimes you get cheap rubbish. Although my Cross8 was tuned for 95 or E10 and ran fine on both, developed good power on both, just used a little bit more fuel on E10 but not 10-15c/litre more that you pay for 95. It pinged its guts out on normal ULP. My SR5 Hilux actually runs better and gets better economy on E10 than it does on straight ULP or 95 octane ULP. I tend to buy it from high volume sellers though.
I must be the opposite you, mine will run on after turned off and also ping on heavy accleration on 91 or normal unleaded.
(wasnt super or leaded 96 octane.)
i have seen 3-4 late model engines say from 93 to 2002 pulled apart that have been run on e10 and the valve recession was terrible, also a green tinge on all the back of the valves, maybe its the fuel we get in albury, but everyone i know that has used it has had major problems and engine damage, i wouldnt even run my 2006 commodore on it.
