🛢️ Oil Change Reminder
Calculate next oil change date and mileage
About this calculator
Clean oil is the cheapest engine insurance you own. Enter your last oil change date and odometer reading, plus your oil type and driving conditions, and the calculator tells you when the next change is due — by both kilometres and date. Conventional oil runs about 5,000 km; full synthetic stretches to 8,000–12,000 km or roughly once a year, whichever comes first.
Tip: if you mostly take short trips in a Canadian winter, the engine rarely warms fully — change on time rather than mileage, since moisture and fuel build up in the oil.
