Every vehicle manufacturer has its own service interval that reinforces its marketing strategy. We recommend following the manufacturer’s service interval. However, if your long-term goal is to keep the car beyond its warranty period, then we recommend one intermediate oil change in between services.
For example, most BMW and Mini Cooper models have a recommended service interval of 15,000 miles. Therefore, we would advise an oil change every 7,500 miles and 5,000 miles for Audis and newer BMWs and Minis since their service interval is 10,000 miles. If you are a low-mileage driver, then we recommend an oil change and/or service once per year.
Why do we recommend a shorter oil change interval? Your oil lubricates the moving parts of the engine, but with the heat and friction in this environment, the oil will eventually break down. The fresher the oil, the better job it does, keeping your engine running smoother. The less wear and tear on your engine, the longer it can keep your car moving. Additionally, since high performance engines naturally consume oil, you should check your oil level often. Running your engine low on oil can cause excessive wear, engine damage, etc.
BMW has stated that their engines can consume 1 quart of engine oil per 750 miles, and M models can consume 2.5 quarts per 1,000 miles. Audi states that consumption of 1 quart per 630 miles is normal. Keep in mind these numbers are the limit, and the norm is approximately 1 quart every 2,500 miles.
By performing an intermediate oil change and checking your oil level frequently, you increase your engine’s longevity and reduce the risk of damage. Don’t take our word for it: Even BMW has realized their 15,000 mile interval was unfavorable. Therefore, they recently changed the recommendation for their new models back to 10,000 miles.
