Not a typo, the trend is going towards longer service intervals for all new vehicles. Manufacturers can claim lower servicing costs....
Most mineral oils will only last 3k to 5k before the oil molecules start to shear and break down, longer with synthetics.
A bike is much harsher on oil than a car because the gearbox and clutch are lubricated by the same oil as the engine....
Anyways, it's all academic in the end...... change your oil each 2500km and your engine will last forever, change it each 10,000 and it'll probably last a bit less than forever...... I always recommend the aircraft owners change their oil each 25hrs, proven to help the engine last a lot longer.....
If you want have an oil analysis done, you'll know the condition of the oil as well as the engine, that'll give you an excellent idea of when to change it. One company is Wear Check in Bris 32437203, good service
