At what percentage of engine oil life remaining should it be replaced?
1 Answers
Generally speaking, engine oil should be replaced when its remaining life falls below 20%. Here's more detailed information: 1. Oil changes should be performed based on mileage. 2. The vehicle's onboard computer settings should be considered - when properly configured, the system will alert you when the oil reaches replacement indicators. 3. Conventional mineral oil should ideally be changed every 6 months or 5,000 kilometers, whichever comes first. 4. Semi-synthetic oil can extend this interval slightly, with replacement recommended around 7,500 kilometers. 5. For full synthetic oil, which has better oxidation resistance, the standard recommendation is annual replacement or every 10,000 kilometers, whichever occurs first.
