I am really impressed with this Mercury 4-stroke oil. My car runs smoother than ever after switching to this 25W-40 blend. The case of three gallons is great since I like to do my own oil changes. Highly recommended for anyone needing reliable engine oil!

Oil Arrived Opened and Leaky
Unfortunately, my case of Mercury engine oil arrived with one of the bottles opened and leaking oil. I contacted customer service, but it took a while to get a replacement. The oil itself is probably fine, but I’m disappointed with the packaging issues.

Decent Oil, But Shipping Issues
The engine oil itself seems fine—I use it in my boat, and it works as expected. However, the delivery took longer than I anticipated, which was a bit annoying. Still, the quality of the Mercury brand gives me confidence in my choice.

Great Oil for My Lawn Mower
I bought this Mercury 4-stroke synthetic blend engine oil for my riding lawn mower, and it's been excellent. The 25W-40 viscosity worked perfectly, keeping my engine running smoothly. I appreciate the 3-gallon case; it’s a great value for the price, and it should last me a while!
