AOA, I have purchased Honda CB 150f recently, which brand is the best for this engine and also recommended the oil grade pls. I am not satisfied with Honda oil grade 10w30. Kindly advise.
you can consider zic m9 10w40 (made in Korea imported one)https://zicoil.pk/product/zic-m9-10w-40-vhvi-tech/other than that,amsoil 10w40 metric racing oil, depending upon budget you can pick one
When to change it after 1k kilometers or more?
