Thanks. Is it Amsoil 5w20 thats 9 centistokes at 100c? if so go for it , its close enough, to what your happy with. The last time a ran Amsoil a few years back, their 5w30 was more like 12 centistokes? I cant remember which one it was! If you live in a warm climate I would go with a heavy weight 5w30. you won't see much milege improvement with only a 1 or 2 centistoke reduction, so go with the cheaper or more readily available one. I live in Canada and its not that hot so I feel safe running a lighter weight. If I lived in Texas for example I would find a 5w30 on the heavier side.
