How Often to Change Synthetic Oil? (Every Car, Every Driver Explained)
Stop following the outdated 3,000-mile rule. Here is exactly how often to change synthetic oil — with manufacturer-by-manufacturer intervals, severe vs normal driving breakdowns, and what happens when you go too long.
How often to change synthetic oil: Every 7,500–10,000 miles for most modern vehicles using full synthetic. Toyota and Honda recommend 5,000–7,500 miles. BMW, Mercedes, and Volkswagen recommend 10,000–15,000 miles. Severe driving conditions (frequent short trips, towing, extreme temperatures) cut any interval by 30–50%. The 3,000-mile rule is obsolete — it applies only to conventional oil.
