No more Mercury/Quicksilver oil for me
I have been using Mercury 25W40 oil for over 20 years in my Mercruiser stern drive engines. I got tired of paying a very high price for semi synthetic oil and waiting for Mercury to come out with a full synthetic. I also like the 5 quart container vs the Mercury 4 qt container. I am a dedicated TRIAX user now.

Need Up arrows on box
25w40 marine oil, 5 gallon bucket leaked out a small amount of oil around the lid seal, the box needs up arrows so the delivery drivers know the proper orientation of the package so maybe it wound not leak. the oil it self seems to be preforming great in my boat engine 1998 Volvo Penta 5.7l GS 350 CID Chevy engine
