The weather is finally turning warm and it’s time to get your BMW in shape for the coming summer. You may be planning to do an oil change on your BMW yourself, rather than bring it in to a shop.
If you have the right tools and know what to do, there’s no problem with it.
We want to make sure that you have the right information for the summer driving season.
What kind of oil should you use?
There are so many myths surrounding engine oil that we’ve been led to think that winter driving is different than summer driving when it pertains to the oil. In truth, the two numbers that you see on the oil represent cold and hot temperature protections.
Higher viscosity oil is said to protect better. Whether you choose 10-40 or 5-30 isn’t going to matter all that much unless you’re planning on taking your BMW to the track and really pushing the engine to its limits.
Most BMWs require synthetic blends, though. This is more expensive than regular oil and offer a higher level of protection. If you change to standard oil, you could end up having trouble with your BMW before long.
Don’t forget to change the filter.
Your BMW probably doesn’t have the same type of oil filter that you may be used to seeing on other vehicles. BMWs use an actual filter cartridge that sits inside its own reservoir cap. Other oil filters will unscrew by hand and then go back on in the reverse process. You will need a special tool to remove the oil filter casing, drain the oil from it, remove the filter cartridge, and replace it with a new one.
While this may be frustrating for some people, it’s important that you don’t skip this crucial step. Why? When the new oil passes through an old filter, it will become instantly contaminated and the foreign materials that were trapped by the filter could then be flowing back through the entire engine, causing damage and reducing the protective nature of the oil.
Resetting the oil change light.
On your BMW, you likely have an oil change indicator light. This might be a series of squares, highlighted in green or the number of miles left before it’s next due. When the life of the oil begins to diminish, you’ll be able to tell with this indicator.
Be sure to manually reset this oil change indicator light or system for your year and model BMW.
