I get a set of Maxell T-120s.To be honest every quarter I get about £15-20 in shell fuel vouchers.
I'm not sure they'll raise the octane. Shell have already been told off by the advertising bodies for suggesting that octane improves performance so if they did raise octane they'll have to rely on the public's incorrect assumption that more octane will be better for them. I'd rather not pay more money for more octane I don't really need.Yes but raised octane = more money, Its already £1.30 a litre. And with evo economy it doesnt last long
