hi all. when i had my 1.9 asv 110 cambelt changed i had the garage change the oil aswell. the guy mentioned something about it being a pd engine and using pd oil. i now see that it not a pd engine and uses non pd oil. so if he has put pd oil in it, can i top up with non pd oil or does it have to be pd oil. as the oil is low and needs topping up.
thanks.
