The below data is what i have recorded so far in my 2007 Corolla SX hatch
All figures are based on the same road and distance travelled (Sydney to Newcastle freeway 131km's), with the average fuel per 100km's meter cleared at the start of each run.
United PULP 95 7.2/100
Shell unleaded 91 7.1/100
Vortex 98 6.5/100
Would still like to try Shell V-power racing 100, but this is only sold at very few stations.
I have a fitch fuel catalyst which i intend on installing in the next few months. I recently lent this to a friend (ford falcon ute) who claimed he acheived an extra 100km's on his return trip to Queensland. So i will advise you of the outcome of this once it is installed. At that stage i will also be running the car on Amsoil Synthetic oil.
