That's true. But if your car in warranty you don't have choice because if you won't use Honda's oil it will void the warranty.
Yes keeping in mind hot weather and constant AC usage in summer, SN 5w30 is best choice for Pakistan's weather. The recommended oil for R18 engine are 0w20, 0w30 and 5w30. I don't believe liqui moly have fully synthetic oil in 5w30.
Rest choice is yours
