The 40,000 km service is the first true major service your car receives. It's significantly more expensive than a standard oil change service — and it's also the service where the most unnecessary upselling happens. This guide tells you exactly what should be on a legitimate 40,000 km job card, what's optional, and what to refuse outright.
What is genuinely needed at 40,000 km
These items are specified by virtually every car manufacturer for the 40,000 km interval:
- Engine oil and oil filter: Always. Non-negotiable regardless of when you last changed it.
- Spark plugs (petrol cars): Standard copper plugs need replacement at 40,000 km. If you have iridium plugs (most modern cars), they last 80,000 km — check your owner's manual before agreeing to replacement.
- Air filter: Replacement at 40,000 km is standard. Cleaning is insufficient at this interval.
- AC cabin filter: Replace. A clogged cabin filter reduces AC performance significantly.
- Coolant flush and refill: Coolant becomes acidic over time and corrodes the cooling system. This is genuinely important — don't skip it.
- Brake fluid flush: Brake fluid absorbs moisture and degrades. At 40,000 km or 2 years (whichever comes first), flush it.
- Fuel filter (diesel and some petrol cars): Mandatory on diesel engines every 20,000–40,000 km.
- Drive belt inspection: Visual inspection for cracks or wear — replacement only if needed.
- Suspension and steering check: Inspection only, not automatic replacement.
What's optional at 40,000 km
- Wheel alignment and balancing: Recommended but can be done separately if recently done.
- Battery load test: Good practice, especially if battery is over 2 years old.
- Throttle body cleaning: Only if you're experiencing rough idle or hesitation — not a routine item.
What to refuse at 40,000 km
- Engine flush (engine cleaning): Not required if you've been changing oil on schedule. An engine flush on a well-maintained car can dislodge sludge and cause more problems than it solves.
- Fuel system cleaner: Marketing product. Regular fuel is sufficient.
- AC freshener / sanitisation: Optional comfort item, not maintenance.
- Shock absorber replacement: Unless there are symptoms (bouncing, noise, poor handling). At 40,000 km on normal Indian roads, shocks are unlikely to be worn out.
- Tyre replacement: Unless tread depth is below 2mm. At 40,000 km, most tyres have 50–60% life remaining.

How to get the best price
Get a written itemised estimate before handing over your keys. Ask the service adviser to walk you through every line item and confirm it's in your owner's manual schedule. Decline anything not on the standard list. At a multi-brand garage after warranty, the same work typically costs 30–40% less.
