Thanks for the reply Paul. My concern is that it has been topped up with water. Completely white. The seller is saying that they topped it with water because they didn't have anything else. As you are saying is long live anti freeze it wouldn't need to be topped up. My concern is what if that antifreeze is going into oil and mixing up. The car has stood off the road for months so if they changed the oil and left it without running I will not be able to see/smell water in the oil.
