Hello all , Picked up my antara which as a Q car supposedly was serviced and oil and filter changed . At the time i did not check engine oil dip stick to check if oil was clean . But i did after 80 miles and was surprised that oil was already discoloured . I checked with garage and they are say oil and filter were changed ,but i am not sure . Garage foreman said it does discolour quicker on antaras . Does anyone have similar experience on oil colouring ?
