It calls for 5w30, iirc. 0w20 is, in essence, 5w20, with additives that effectively thin it to (almost) 0 viscosity when it's cold. Since oil thickens as it warms up, I don't really see where the issue would be. I'm running 15 cold viscosity oil right now, and it doesn't burn oil when it's cold... So 20 weight shouldn't burn when it's warm and clearances are tighter...
