## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great oil for marine applications
  

*by D***D on Reviewed in the United States on 28 March 2024*

I use this in my Baja 26 Outlaw equipped with the 496 MAG HO. I change my oil & filter once per season regardless of hours, and always use this oil along with a quart of Lucas synthetic oil stabilizer. High RPM use and hot ambient temps break down oil quicker and this helps to keep the oil cleaner, longer and keeps oil pressure high.
