Car just serviced, despite being on Time and Distance, they put in Longlife Oil, which going by other posts is the norm. I've got a top up litre of Castrol Edge in the boot, will this be compatible with what they put in?
Got to say I question whether they changed the oil as the car only has 3500 miles on it. I expected to see clean golden oil but it doesn't seem so. Is longlife a darker colour? The filter has been changed for sure, as I have a previous under bonnet photo but jury's out on the oil
