No it's not. That is old ustaad ji logic valid in 70s to early 90s.
Not anymore.
0w20 is the engine oil of choice since 2 decades.
MAX 5w30. Don't go thicker than that.
That diagram is misleading, inaccurate and not valid in today's times.
Check any user manual of car from manufacturer. Since at least a decade 0w20 to max 5w30 is recommended.
