Unfortunately, the quart I received was leaking due to a crack in the container. I was able to use some of it, and it seems to work well in my outboard, but I’m disappointed with the packaging.

Good value, but packaging issues
The oil itself is good, but the quart container arrived slightly dented. It didn’t affect the product, but it was a bit annoying. Performance-wise, it works great in my outboard motor!

Engine sounds great now!
Switched to this Sierra 10W30 oil for my 4-stroke outboard and my engine runs quieter and smoother. I love how easy it is to check the oil levels too. Highly recommend for any boat owner!

Great oil for my outboard
I've been using the Sierra 10W30 oil for my 4-stroke outboard for a couple of months now and I love it. The engine runs smoothly, and the oil seems to hold up well even in warm weather. Definitely a solid choice!

Not what I expected
I bought this oil thinking it would be better than what I had before. It works okay, but I didn’t notice a huge difference. Maybe I expected too much. Still, it seems fine for regular use.
