Synthetic Oils Integrity, Road Trip Options

[RavenAegis45]

I'm planning a road trip basically from Los Angeles California to Nashville Tennessee my question is the whole trip back and forth is a little under 4000 miles (each trip is roughly 1991 miles according to mapquest). My question is since im planning to change my oil not long before the trip would it be able to handle the stress of the whole trip there and back or should I look into changing it while over there? I understand highway miles are alot less stressful on oil than stop and go city traffic but its still a long trip. And I am taking care of other issues namely brakes, suspension and other fluids as well but the oil is my biggest concern
