We've used this oil in our previous boat and our current boat. Our old boat had the 4.3 V6 in it and the new one has the Mercruiser 4.5 V6. We've never had any engine issues with either boat. They both had good oil pressure with no engine noise aside from the expected. Even after it sits for a while I've never heard any lifter noise or anything like that when I first fire it up.
Bottom Line
Yes, I would recommend this to a friend.

Great Oil lousy Shipping

This is some of the best oil available for Mercruiser engines that I have ever used. The three star rating is for the shipment. Half the bottles were leaking oil from the caps. Enough to soak thru the boxes. Neighbor had the same problem with motor oil delivery.
