Oo really
0w16 is recommended for non hybrids like Swift 1.2 litre with K12M and K12C engines
And 0w20 is recommended by manfacturers for hundreds of non hybrids till now
Like 1kr fe in vitz passo, 0w20
And suzuki k10b, even maruti suzuki recommends 0w16 for that, also 0w20,
Cultus/ celerio k10b, same 0w20
Suzuki ciaz, ertiga, same 0w20
Corolla 1.8 grande, Civic 1.5 turbo, same
Many others too
Edit: even for suzuki M13A like old engine, 0w20 is recommended by suzuki
