welcome to the forum

good to hear you're using quality products on your Spark. I guess your doing these oil changes by yourself at home?

You can try 5w20, since it's thicker (am i right?) it should help with keeping the engine cooler and maybe resulting in better performance, rather than a thinner oil that would allow for more friction when fully heated up.
