Regular oil changes keep your engine running smoothly and prevent costly damage down the road. But the old "every 3,000 miles" rule is outdated for most modern vehicles.
Most manufacturers now recommend oil changes every 7,500 to 10,000 km (roughly 5,000 to 6,000 miles) for vehicles using conventional oil, and up to 15,000 km for those using full synthetic oil. Your owner's manual is the best source for your specific vehicle.
Several factors can shorten this interval. If you frequently drive in stop-and-go traffic, tow heavy loads, drive on dusty roads, or make many short trips (under 10 km), your engine works harder and the oil degrades faster. These are considered "severe" driving conditions, and most Canadians experience at least one of them regularly.
Watch for these warning signs that your oil needs changing sooner: the oil looks dark and gritty on the dipstick, your engine sounds louder than usual, the oil pressure warning light comes on, or you notice a burning oil smell.
Modern vehicles often have an oil life monitoring system that tracks your driving habits and tells you when it is time. Trust this system over a fixed schedule since it accounts for your actual driving conditions.
The cost of an oil change in Canada typically ranges from $50 to $120 depending on the type of oil (conventional vs. synthetic) and your location. Skipping oil changes can lead to engine sludge, overheating, and eventually engine failure, which costs thousands to repair.
