Great stuff
Great stuff for my mercury motor. Did the oil change myself and saved lots of money from what the dealer charges.

Good quality good price.
At under $10/qt for high quality marine full synthetic, this is one of the best deals on Amazon. Other marine oils are upwards of $20/qt where I live and having twin outboards that require a total of 8.5qts each every change, that is a real savings. The other great thing about this oil is it’s packaging. The shape of the container and the pull out spout make it easy to pour. I don’t need to use a funnel with these and I didn’t spill a drop.

High quality oil
Liquid moly oil is great stuff. I bought this for my Honda 9.9 outboard. I’m sure non marine grade oil would have been fine, but for the price and quality of this oil why not use it.
