So today at WM they were out of 5 quart jugs of 5w30 Mobil 1 that I usually run in my 2012 Nissan Pathfinder VQ40 DE V6 so I went with M1 10w30 I'm sure it will run fine as May people run 40 weight oil in VQ40 V6 motors without issue. My question is for my trailer towing summer season is the M1 10w30 a better choice over the 5w30 or will it even matter?
