Best full synthetic oil I ever used.
This oil I use in my outboard and I also buy another wt oil for my car. My cars mileage went up 2-3 consistent MPG on the digital mileage counter and use in my 2020 Merc 40hp and the outboard runs smoother and oil stays clean longer. Confident in this oil better than re-branded oils and higher cost. This oil exceeds by far manufactures oil ratings. Use high quality oil filters also.
