I’m going to purchase this product again. I drive a lot and it’s perfect for me and yes, it does work in my opinion. I noticed a difference right away after the oil change. My vehicle was much smoother.

Got this for my 2015 Subaru outback for its notorious oil consumption. It seems to be doing the trick causing less oil consumption after 1k miles noticable difference for sure.
