17000 miles is ok with modern good quality oils.

The reason why I know is because I deal with oil samples for our durability cars at work (I'm an engine development engineer at a luxury car brand in Crewe.......) - the oil sample results I get back for similar mileages show that oil viscosity is still acceptable and lubrication properties are still high enough for component protection.
