Im coming up for my 2nd year service and was wondering if i can buy my own oil and filter, was thinking of, and could i use any of these for the filter, i will be going to MIDPOINT Garage in middlewich to have it done, can he refuse to use what i supply or demand i use his same stuff at inflated prices, last year i used same guy and charged me £48.75 for oil and £11.29 for filter without vat which was @ 15% and no doubt he put prices up and vat @ 17.5%, and does anyone know what Arnold Clark in Winsford (closest to me) charge for their oil and filters, thanks guys.
