Awesome stuff
Number of Items: 1
This stuff is awesome. I just did an oil change on my 2001 suburban with 400k miles and It increased my oil pressure at least 10lbs. Very impressed. Even made the engine tap disappear. Will recommend.

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.
