Is this a problem? Its usually when Ive been driving for a bit and stop at traffic lights and can there are at least 5 other cars around me, so i wonder if its just a collective smell from all the cars, or if it's just me? Im driving to dp's tomorrow which will take at least an hour and a half and will be mostly on M25 so don't want to drive if my car is going to break down on me especially as this will be my first time on the motorway on my own! Im going to check the oil levels tomorrow morning when it is light as I dont have a torch to see.
