I use any garage, i get out of a class 1 and get into a Peugeot 106, 
i always stall the thing on set off because i end up pressing revs and brakes with my right boot,pedals are like a 2 pence piece, but i just drive it for fuel economy. sorry not one for posh cars there a piece of metal to me.
Use Shell as it is closest to me poss 1p pl more than the supermarkets ( which I would have to go out of way for )
I do get more mile to gallon on shell full tank will do me about 400miles on a 2lt V merc clk
hotel magnum:
both teso at Westbourne and tower park poole have had major problems, wrong fuel, dirty fuel and cleaning fluid left in tanks ?, Westbourne shut for some months, lots of coverage in the paper but no comment from Tesco other than investigations under way.
