Here is the deal, I have a 2014 ford fusion with the 2.5 w/o turbo, and it has 17000+ miles on it. It last had the oil changed in march of this year with MC 5/20 and MC filter. It was then short tripped for a couple months, then taken on a 700+ mile trip, and 700+miles back home. over the next months it had a couple 100+ mile trips, but all the rest of the miles were short around town trips. For a total of about 3500 miles to date. Now in about 2 weeks I am going to drive it about500 miles then in a couple days back home 500 miles. My question is--- do I change the oil and filter before the trip or after. I won't change it again till spring, with lots of short winter trips. I live in Nebraska, so cold winters, but the car is garaged, and it rarely gets to below freezing inside. Also the oil I will be putting in will be QS 5/20 full synthetic, with a fram ultra filter.
