The Tundra and the Lexus GX 550 use the same engine.
The Tundra powertrain also uses HV, but the engine is the same.
The V35A engine is produced in both Japan and the United States, depending on application and build year.
Primary manufacturing plants:
1. Toyota Motor Manufacturing Alabama...
My 2 cents...
If your vehicle is leased, follow the owner's manual; if you purchased it, consider more frequent engine maintenance.
You can follow the owner's manual and listen to the dealer...Or change the engine oil and filter more often.
The V35A engine should have regular maintenance...
