I was in a similar situation this past summer. Except mine is a mini-van. PP 5w-20 that was in, was around 4500-5000 miles into it. Drive to FL is 2000+ miles round trip. I could have just changed the oil when I got back from Florida...
But I factored in the weight. We were 6 people in the van.. along with the whatever stuff in the cargo, plus a roof bag. So I knew the engine will work harder due to added weight. Plus speeds of up to 80-90 mph. I opted to change the oil before the trip. Gave me peace of mind. Oil is cheap. $22 of PP, is worth my peace of mind.
More important is the condition of the tires. If tires are good, just put manufacturer recommended tire pressure. I never subscribe to the idea of over-inflating a bit for the fuel economy. IMO, any fuel savings is negligible, compared to cost of the whole trip, especially that gas prices is lower now. Proper tire pressure if safer.
If you really want better mpg, there are other ways of doing it... Like driving 65mph or lower. Gain speed before a hill, do not accelerate uphill, and go easy & let it pickup speed downhill. Drive steady, and anticipate other cars movement, and avoid them. that will allow you to avoid slowing down. Go easy on the airconditioning. etc. etc. etc.
