agreed, i just find that there is a heap more from shell fuel.
guess it just comes down to personal preference really.
shell was my problem as well iam seeing a trend....:p
dam that 4cents a ltr sucks me in everytime!
bp 10%/5% off is better ^^
gotta sign up to their CC and they'll give you 10% off for a month then 5% after that, but you gotta use the cc to pay for the fuel
Lol, I was explaining this about how shell was dodgy fuel in another thread, no one seemed to believe me.
Believe this. :)
