Salam to all after reading you must be like again this dumb question the problem that in every oil thread things are so confusing and messed up so the purpose of creating this thread is to keep things simple and choose the best oil with ODO reading so that members can decide easily what drink to put in their bikes. So previously I was using Valvoline 4T 20w 50 in my 70cc it was performing so good that when I bought 125 I just poured Valvoline without a second thought but the problem is that oil is not performing upto mark also its not available online from where I used to purchase so I did a little research here at PW and found the oils considered best according to fellow riders so the confusion is which one to choose also if you know another oil please mention below with viscosity and grade try to keep things simple for other rider fellows my bike has clocked 5k+
Castrol Activ 4T 20W50
Castrol gtx
Caltex havoline
Shell Advance AX5
PS I am no pro so if I made any mistake kindly guide me . Thanks!
