But you can also get some value brand 0W-40 synthetic oils. I stick to the store brand 5W-40 at the moment. I've heard arguments that the low 0W- oils contains more of those viscosity stretching additives, which burns out quicker, but that is probably hearsay. The store 5W-40 does the job nicely, the engine hums over quietly, you can really sense the smoothness when the oil has been changed. Johannes
