Right oil for my bmw
It has worked great for me for the BMW X5. The price is great. I am purchasing these for a few years now I know every Bmw needs to have one Handy in the car just in case the signal comes to add more oil. I am very happy with this product.

BMW Branded Oil
The is Genuine BMW branded oil that I use to top off my oil changes for 5 litters. Definitely a little pricy, but it is BMW branded. I'm sure there are products that are comparable at a lower price point.
