Being a tanker driver, doesnt all the fuel come from the same wholesale depots? is it really different? i only ask as I tried switching from sainsbury fuel to shell for a month and the only difference I noticed was in my pocket (and nectar points.....
)
and on the mpg front, I have an S4 now so obviously cant look at mpg as its too depressing, but before this a had the 2.5tdi cab and with a remap (that added 4-5 to the gallon plus a big smile) I was getting 36-38 around town 50+ on a run. All from the dis so taken with a pinch of salt of course.....
