i converted back to BP ultimate after goin on optimax and vortex the last few fill ups....
and i'm finding my fuel consumption on ultimate quite consistent...running at 9.1-9.5L/100kms (100% city driving)...
on vortex and optimax i had +10.2L/100kms...
finding it quite weird though since other euro owners don't see the same result i do with ultimate...
must be my driving habits? :wave:
