I used AHL till my first 2000 KMS, After that i moved to Zic 4t 20W-40. It sure was an improvement over AHL, But due to the Viscosity being less i guess, My bike started to heat up a lot and produce more sound after 800 KMS. I got it drained at 2850 KMS and poured in again Zic M7 10-40 and the results are even more worse than the previous one. I am at 3900 KMS currently and confused between Kixx Ultra 4T and Liqui Moly. I am in Multan and the issue here is that its very hard to find both these. Even if someone has one of them or both of them i still remain at doubt whether these are original ones or not.
One more thing, The basic viscosity level recommended for CG125 is 20W-40, but i think 20W-50 is a better choice because i have seen both 10W-40 and 20W-40 performing their best but in the end both failed.
