I have changed my first engine oil in my Suzuki Gd110S at 850 KMs after initial free service maintenance.
I have put in Liqui Moly 20 W 50 Engine oil 1000ml in my bike. And replace Engine oil filter with Original Suzuki.
My verdict: the bike has become more responsive and engine sound is decreased. Pick is improved.
y not 10 w 40 ? as it is spacified by the company ?
10 W 40 is not good for such high temperature here in summers.
It is thin and has low temperature limits.
10 W 40 and some others can also be used. As they are mentioned in User Manual of Suzuki Gd110S.
