C'est vrai, mais ça revient cher, je le fais chaque 10000

I do around 17k miles a year. Car goes in once a year for a service. An average car mileage a year in the UK is around 10k. That seems very low. My car would be in every 3 months

Haven’t done an oil change for three years.

Enak per 3500 km dah ganti

I do it once a year, which never reach 5000km/year so.... well, each has their preference

Every two years or c30,000 km (whichever is first) based on BMW service schedule. Diesel X5, for reference.
