E10 vs Regular Unleaded for P38

[redandy3575]

What is everyones thoughts about E10? and would you recommend using it in P38 Rangies?

[DT-P38]

I'm not touching it... but most of my km's are done on gas. The petrol I do give my 'pretty pig' is generally premium unleaded. The benefits of that have been debated somewhere here before... I just figure she can have some 'nicer' juice considering that she doesn't get it that often.

I've done some testwork myself and here's the results:

91 Octane - Lower performance and worse economy (urban cycle of approx. 20l/100km).

95 Octane - Great performance and reasonable economy (urban cycle of approx. 15l/100km).

98 Octane - Same performance as 95 Octane but worse economy (urban cycle of approx. 17l/100km).

I don't ever plan on touching E10 or the like, and I don't have any real scientific documentation to back up my claims (notepad with GPS kms and bowser reading), but mine gets 95 Octane at every fill!
