### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good product.
  

*by F***R on Reviewed in the United States on September 7, 2018*

Cheapest synthetic option for my boat. Good product.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Company stands behind their product... and listing verbage!
  

*by G***. on Reviewed in the United States on November 22, 2022*

I've used this oil for years in my Volvo Penta 5.0L.  But these 5-stars are mostly for the supplier, Neobits. The listing says you're buying a 4-pack, but only 1 container arrived. After calling Amazon CS, Neobits got right back to me, explained that it was a listing error and refunded my full purchase price, no questions asked, while I got to keep the 1 container I got. Thanks, Neobits!

### ⭐ 1.0 out of 5 stars







  
  
    Price per oz. is not 9 cents
  

*by J***K on Reviewed in the United States on May 4, 2023*

If you don't mind paying $.34/oz, and NOT the $.09/oz shown on the listing, then I expect you will probably be satisfied with this product. The trouble is that when the listing indicates you get a "4 pack" of "5-quart container", I expected to get that
