I drive a BMW, and this is the oil I always keep with me in the car. I even have a special holder made for this exact bottle, because it fits perfectly and I trust it that much. The oil quality is excellent, and since it’s fully synthetic, it performs well even during long drives and temperature changes. In terms of functionality, the engine runs smoothly and quietly after each change. Longevity is also great. I notice that the oil keeps its properties for the full interval, so I don’t have to top it up too often. There’s also no oil leakage from the bottle, which is important when you store it in the trunk. For a branded BMW product, I think the value for money is good, especially if you service your car yourself or like to have backup oil on hand. Overall, a dependable synthetic oil for anyone who wants to use what the car was designed for.

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.
