Petrol: every 7,500-10,000 km। Diesel: 10,000-15,000 km। Synthetic oil: 10,000-15,000 km। Indian conditions (dust, heat, traffic): change MORE frequently than manufacturer says। Cost: authorized service ₹2,000-5,000। Local garage: ₹800-2,000।

Tips

Castrol, Mobil, Shell: premium brands। Local garages 50-60% cheaper — fine for routine service after warranty period।

⚡ CalcWolf Insight

Quick-lube chains (Jiffy Lube, Valvoline) recommend oil changes every 3,000 miles because it doubles their revenue per customer. Your car manufacturer recommends 7,500-10,000 miles for synthetic. Follow the manufacturer, not the shop that profits from more frequent service.
