read somewhere on these forums that other CL9 owners get more kms out of their tank from Mobil Synergy.
So i decided to fill up @ 7/11 Mobil.. and unknown to me the Mobil Synergy was no longer available and had been unavailable for many years.. i didn't know this since I've never filled @ Mobil nor 7/11 due to always filling at BP (ultimate) & Shell (v power) in all the cars I've owned.

Anyway, i was already low in the tank with about 15km left and decided to fill the CL9 with Mobil Supreme 98 (red cap).

Has anyone had Good/Bad experience with Mobil Supreme 98?

My last tank got me 543km from 60L roughly 11L/100kms using BP Ultimate.
