Regularly scheduled oil changes are the key ingredient to a healthy engine. Using BMW Factory approved oil and filters is the most important aspect of all BMW specific oil changes. But just as important is the interval – most BMWs oil change should occur every 5-7,000 miles [or once per year on seasonal cars]. But why does BMW recommend every 10 to 15,000 while under warranty? In short, that’s changing and does change when out of warranty. What’s not considered in these German engineered cars is our American way of life. The high levels of ethanol in our fuel, and the way we drive. Lack of regular oil changes are causing a long list of issues now that range from oil usage to deposits on pistons [for which there now is a treatment].

Case: We did a pre-purchase inspection on a 2015 5 series. In the process we opened the oil reservoir to check the level, and discovered a good amount of burn on oil on the head of the engine. The vehicle was freshly out of warranty and only had it’s oil changed every 12,000 miles. To compare and show the client how important oil changes are, we opened the oil reservoir to a car with the same engine, which has had regular oil changes every 5-7,000 miles [frequent drivers can stretch it to 7,000].


With regular car oil changes, your vital engine parts stay well-coated and protected against excess heat and friction. When you skip oil changes, the oil begins to thicken, break down, and is consequently less effective, resulting in damage and engine wear.

When you don’t change your oil regularly, you could end up needing costly engine repairs or even an engine replacement. Don’t risk it – follow your vehicle’s maintenance recommendations. It will save you a lot of time and expense in the long run, and in the short run, you’ll even save on gas, as a well-oiled car burns fuel more efficiently.
