kinda confusing! I've just picked up a 1998 VW Golf with 105,000 miles on it. It does not currently leak any oil, and appears to have been using 10w40 and 10w30 dino oil for most of it's life in California.....I'm in NYC now (abusive city driving).....should I change it out to proper VW spec syth 5w40, or should I just feed it what it knows to avoid leaks? Any pros-cons?
Thanks!
Thanks!
