Same notice here , DONT BUY ASDA FUEL , ITS RUBBISH , same as Sainsbury and Morrison's fuel "rubbish "
I've got a highly modified Bike and it wont get out the forecourt on Morrison's petrol , pops and farts bangs and splutters it does .
Got a guy comes for service with an L200 , he does moon miles per year , so 2 maybe 3 times a year its in for service , New Fuel filter every time as its blocked , Because the firm he works for has a Morrison's fuel account . found fuel rail issues once and it was the filter .
Another Hyundia i10 customer took her car to ASDA from us EML light on as it left the place , she bought it back , we checked it out turned the light off told her to fill it up with Shell or BP round the corner and it was fine afterwards never a problem since . .
There will be stories the other way I know , but I wont go near them .
