I have a goofy question. I use synthetic oil in my Traverse and go 10,000 miles between oil changes. Do you think it helps to change the oil filter at 5000 miles if I'm using the AC Delco filter that comes from GM? Or should I not worry about it until the next oil change? I know some are going to say that I am crazy for going 10,000 miles and that is fine but I am just looking for opinons on the oil filter. Thanks.
