I bought my first Volvo a few months ago and it's a 1998 V70 (non-turbo). I am trying to get the best gas mileage I can get out of it. I already changed the timing belt and the spark plugs. I understand that the car has a whole PCV system rather than just a valve. How would I go about cleaning this system out? Also, if any of you know any other ways to improve gas mileage, that would be appreciated.
Thanks, Matt.
