05 Expedition with 180k miles, since 2 month period of time , I place all brake , new coolant ( motorcraft ), fuel filter, air filter.....
rear diff I replace with valvoline 75w140, but I had to add half quart of OLD OLD ( 4 year old ) redline 75w140, should I change this out ?
expy run and drive good, very smooth in town and highway. All good tires. Anything I should check before this trip,
about oil I change it month and half ago with mobil super 5000 , I roughly put 1100 miles on it. Should I leave it alone ?
anything I should add in fuel tank on this trip ? or tool to bring on this trip ?
13 hours each way.
