stievorex said:I suggest you try Q8.Best of the lot.Alot of motorsports fellas also using.120bhp below try 10w-40 or 5w-40.If engine got more power put Q8 F1 10w-50.Very smooth.
As mentioned by bro extemeleo, the number indicates the viscousity of the oil, smaller number for low viscousity (low operting temp) and vice versa (high operating temp)... Btw, what's the first number represents?
20 50W
---------
20 = ?
50 = viscousity
w = ?
