I would like to point out that the most important aspect of motor oil is its rating/ service classification.
Since 2010 onwards the automobile manufacturers have opted for thinner oil, the reason being lesser tolerances in the engines and to improve the fuel economy.
Pls ensure that you use fully synthetic oil having API grade os SN/ Islac GF-5.
Hybrid/ Start & Stop engines have to undergo multiple start ups, due to this reason they require even thinner oil like 0w-20 which ensures that the oil reaches the critical parts rapidly.
As Crude101 has pointed out Atlas Honda is recommending 5w20 in their cars, same is good for Toyota too.
I have kept 2010 Altis for 8 years and through out the ownership I used thinnest oil available. I never had any problem with my car.
