^^^depends on how you drive, could be anywhere between 5 and 10 thousand Km's. In my wifes new corolla we use the 5w-50 mobil and I change it every 6-7000kms, it is still usually very clean though, but then it's a new engine. I also use that oil in my GSR and I change it every 5000km's because of the way I drive and the fact that my car is now 12 years old, and still at 5000km my oil is quite clean, however I'm always concerned about the breakdown in the viscosity (sp.) of the oil.
