I have a Mercruiser 5.7 with 450 hours built in 1988. I'm about to lay it
up for the season (northeast). Does anyone have a suggestion for engine
oil? I'm inclined to use 10W30 Dino oil which is what I use in my car.
The boat is new to me so I don't have a "what did you use last year" to go
by. Any ideas would be appreciated? Thanks, David


Hard to go wrong with MerCruiser's own 4-Cycle engine oil. It's formulated
to their specs for their engines.
