Oil Specification for 2009 Toyota Venza - Will 10W-30 give longer engine life than 5W-20? - oils specification olive

Toyota says 5W-20 or 0W-20 for my new 4-cyl. Venza. It is about the viscosity of water. I suspect that it is specific to less friction at startup to provide and improve the fleet (numbers) km easily. I suspect that these very light oil at the expense of engine life and wear. As the engineers of the automobile with 10W-30 oil in the vehicle of all, even if it means more difficult in the winter game. I bet that other oils have in the life of the engine results in reduced long-term and wants to keep this car for 200,000 miles. No speculation please fans.
