Reporting for Today Tonight on Channel 7 is pretty cool - it gives you the chances to throw significant resources at stories. (And it's v-e-r-y cool to call up the Ch 7 chopper & its FLIR...)
Anyhoo, we got five identical cars and filled them full of e10, 91-, 95- and 98-octane petrol, and diesel, to help decide which fuel drives your dollar further.
I especially liked Professor Tim White's comments at the end, which neatly explains the rough running problems commonly claimed by callers to the motoring programme I do on radio 2UE - Friday nights with Murray Wilton @ 10pm.
