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.

Actually works on BMW!

I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!
