The 2011 Tundra's with the 5.7 came from the factory with non synthetic 5w-20. When I was still under the Toyota Care the dealer said all Toyota recommended was 5w-20, non synthetic oil. The very first oil change after Toyota Care was over, the dealer recommended synthetic. Amazing how that changed.
I am getting ready to change mine soon and I'm thinking about trying PUP or PP 5w-20 or Valvoline SynPower 5w-20. Got a few cases of M1 5w-20 that I bought on sale last year with some Amazon points so I may just use it.
