Ive been doing some experiments - In my Barra 182 equipped XR6, I have been measuring what I can get from a single tank (repeating the tests for accuracy) using different fuels. I have a mix of city and highway driving.
On Mobil Synergy Premium (the 98 OCT one), the best I have got from 2 experiements was 480kms from a full tank. Now from regular unleaded (91 OCT), I consistently get about 480km with a once off best of 520kms. I cant notice any difference in power either. Now although the falcon has a knock sensor, im not sure if it will advance timing (i think its mainly to protect against knock from poor quality fuels). Today I filled up with a full tank of Caltex Vortex (96OCT) will let you know how it goes.
Despite the apparent lack of performance or economy gain, I still fill up with the 98OCT once a month due to the cleaning properties of the fuel.
Did anyone read the Sunday Drive in the herald?? there was a big article about it - they reckon that even if the car has a knock sensor it wont make a difference if the car is optimised by the factory to run on regular unleaded (different for XR6T as this is optimised to run on premium).
Im also investigating getting a programmable UNICHIP, so that the computer settings can be changed on the dyno to suit 98OCT fuel (the only way youll probably get a noticable performance gain).
