For most commuter bikes using mineral oil, change every 2,000–2,500 km. Semi-synthetic oils may last 3,000–4,000 km. Always follow your owner's manual first.
Jaipur dust increases air filter load and engine stress. Combined with summer heat, oil breaks down faster — making timely changes critical for engine life.
Never mix random oil grades. At our workshop we use manufacturer-recommended oils and replace the filter during every oil change service.
