Best synthetic oil for Toyota 4.7

[Pitbull]

Will switch at 5000 miles, now have 2000 on engine. Want to keep the warranty in good shape so I will be doing a 5K mile OCI. I was going to run Mobil 1 5w30 year round. Any other oil or grade of Mobil 1 better for my truck? I live in the Midwest SW Missouri. 90's summer and down to around 0 in the winter. Thanks

Mobil 1 10w30 would work well.

I agree 10w30 is the ticket. Add a splash of 15w50 at the rate of 150 ml. Actually I would go ahead and use 300 ml of the 15w50 with the 8.
