I have PP synthetic in my 4 cyl Highlander right now. I have been doing 5000 mi oci's.
Due to a death in the family I have to travel 1000 mi up, and 1000 mi back, all highway. I have about 4700 miles on this oil so far. Would I be safe traveling the extra 2000 mi over the oci, or should I change it now? It's awfully cold in the garage.
