Best Oil Brand Available
Best automotive oil on the market. Only brand I will use in my cars. Used specifically for a 2018 BMW X5.

Great oil and makes my engine run quieter
I noticed the engine running much quieter using this oil. The pour mouth is pretty unique for this brand, you can just open the interior cap, pull up the accordion neck and pour into the engine which provides better control over traditional wide mouth, thus less messy. This oil rarely goes on sale and is typically 1.5x to 2x more expensive than the more common US brands.
