I am running Valvoline Synpower 10w30 in my 2012 Nissan Pathfinder VQ40DE V6 I have aprox 3,000 miles on the current OCI I will be towing my 5,000 pound camper soon 1,500 miles. The Nissan VQ 40 V6 is known to shear oil even without towing so should I dump it early and have fresh oil for towing or just run the current Valvoline Synpower to my normal 5 to 6,000 miles?
