11 Months & only 8,500 miles on oil. Changed oil in August of 08' & ran until July 09'. First ever Amsoil use on this vehicle, first ever UOA. Ran Amsoil flush through engine with 10,700 miles on vehicle and then added Amsoil. Used Amsoil's oil and air filters. Driving conditions were PA mountains and backroads, 1/4 dirt roads, 1/2 two lane paved rough roads, 1/4 Hwy. Lots of hills. Moderate to easy driving style, minor towing. Regular cheap dino oil was used (Napa) prior to Amsoil.
No top off oil was needed during this run. Xterra is a 4X4.
