The cheapest!
I then add fuel additive to make it premium, essentially, that's what premium diesel is......just save the dosh.
I normally top up at supermarkets.
Tend to avoid Shell as over priced.
Driving mostly with speed limiter and some short and long journeys...most 16 mile trips and the odd occasion where I just throttle it....I'm getting 49.4mpg D4 S90.... Brilliant if you ask me.
