All -
I got my Ninja ex500 last summer & immediately used Rotella 15w40 weight in it, without considering the weight. Seemed ok.
This summer, I am actually trying 10w40 (in Castrol) and it seems to be a smoother shift.
Was I wrong to use a heavy weight for summer last year? My owners manual says use 10w40.....
