Fuel

Actually they had this exact kind of test done in the cars guide comparing between the performance/fuel economy and price of different types of fuel.

Any petrol that had a blend of ethanol was the most expensive to run because of the fact that is has less energy (not to mention screws up your engine.

91 still worked out the be the cheapest and 98 coming second. The test was conducted on a Holden captiva 7 (60l tank) because it can use up to E85 blend.

Fuel economy results are as follows:

E85 - 14.6l/100 (413km) @ $1.19
E10 - 11.9l/100 (514km) @ $1.34
91 - 11.1l/100 (536km) @ $1.36
95 - 10.7l/100 (569km) @ $1.44
98 - 10.2l/100 (600km) @ $1.50

Cost over 20,000km:

E85 - $3472
E10 - $3187
91 - $3017
95 - $3080
98 - $3058

Think the results speak for them-self!

Agreed, except that the typical e10 is around 93-94 Octane (Shell)

I've not seen a test done with 100RON with e10, and would be interested in seeing it in a comparison

Yes - I remember that test - $107 less to run 95 is compelling
It seems like a big price difference at the servo but mileage makes it work out ok
(Other tests have shown E10 to be marginally more cost effective )
Trouble is prices have changed, I have not bought 98 for $1.50 for ages
I just don't worry about price/value any more - 95/98 all the time
