Hi all
Synergy 8000 is possibly the best we can get here ex Mobil refinery at all Mobil fuel outlets.
Shell Optimax and BP Ultima are both ex the Geelong Refinery and both without additives at 96 RON. (Run Octane Number)
So I guess at $1.05 a litre its not that bad. Shell tell us motorists that the more expensive Shell Optimax actually improves economy.
Cheers
Bernie
