Knowing exactly what should happen at each service interval lets you verify the work, refuse unnecessary upsells, and catch it when something important was skipped. This checklist covers the first service, every 10,000 km, the 40,000 km and 60,000 km milestones, and the annual time-based items that matter even for low-mileage cars in India.
Manufacturers set service intervals from engineering data on how engine oil, filters, plugs and fluids degrade in normal use. Following them protects the engine, preserves fuel efficiency and is a warranty condition. The most common Indian schedule is 10,000 km or 1 year, whichever comes first — always cross-check your owner's manual, as some diesels use 15,000 km intervals and turbo-petrols and hybrids have their own schedules.
A run-in check, usually free at authorised centres. The engine oil and filter are changed — the run-in oil carries metal particles from the engine's initial wear-in, so do not skip or delay this — plus fluid levels, leak checks, fastener tightening, alignment and brake inspection.
The standard periodic service. The critical items each visit:
Several monitored items reach replacement age. Standard copper spark plugs are replaced (iridium/platinum plugs last 80,000–100,000 km). The air filter, fuel filter and cabin filter are replaced regardless of appearance, the accessory belt is inspected for cracks, brake discs are checked for grooves and warping, and suspension bushings get a visual inspection.
The most significant milestone. On engines with a rubber timing belt, replacement is due around 60,000–80,000 km — a snapped belt causes catastrophic engine damage, so confirm belt versus chain in your owner's manual. Coolant and brake fluid are replaced, automatic transmission fluid is inspected, and the clutch is checked for wear on manuals.
Some items age with time, not distance — vital if you drive under 10,000 km a year. Brake fluid absorbs moisture and should be replaced roughly every 2 years, coolant every 2–3 years, wiper blades every 12–18 months in Indian conditions, and batteries should be tested from year three. Keep every stamped invoice — a complete record protects resale value, as explained in the service history guide. To decide where to service, see authorised vs multi-brand centres, and if you are evaluating a used car, service records are your best defence against odometer tampering.
Ask for an itemised invoice listing every part and task, and ask to see old parts — the oil filter, air filter or plugs — before disposal. Legitimate workshops comply readily. Photographing the odometer at drop-off and matching it to the booklet stamp is another easy check.
No. The first oil change removes metallic particles from the engine's run-in phase; skipping it leaves abrasive debris circulating in the oil. It is also a warranty condition with most manufacturers, so do it within the specified window.
No. Iridium and platinum plugs typically last 80,000–100,000 km, while standard copper plugs need replacement at 30,000–40,000 km. Check your owner's manual for the plug type, and ask the adviser to show you the packaging before any replacement.
Whichever comes first. A schedule of 10,000 km or 1 year means the annual trigger applies even if you have driven only 6,000 km, because oil degrades chemically with time and brake fluid absorbs moisture. Low-mileage drivers should service annually.
Mostly, with extra checks: more frequent spark plug inspection because CNG combustion runs hotter, plus CNG kit maintenance including the pressure regulator, cylinder valve and pipes every 30,000–40,000 km. The CNG cylinder itself must be re-tested every 3 years under PESO rules.
