Using 5w30 instead of 5w20 in a high mileage engine may be acceptable in some cases, but it’s best to check your vehicle’s manual first. 5w30 oil is thicker and can provide better lubrication for worn engine parts, potentially reducing consumption and leaks. However, if your engine is designed for 5w20 oil, the thicker oil may not flow as effectively, especially in cold starts, which could reduce efficiency. Always consult with a professional mechanic if you're unsure.
