I last changed the oil 2 years ago in my 1996 Ford F350 Powerstoke using Chevron DELO 15W-40 LE. I have ony put about 1,000 miles on this oil, with very little towing. I antcipate towing my 5th Wheel camper on a couple of short distance (200 miles or less) trips this summer. Should I change the oil prior to these excursions?
Thanks
