What kind of oil do you use on your mercruiser motors???? I've always used regular 10w/30.

Doesn't mercury recommend using 40?
What does the warranty require?
I run Mercury's oil. I think it is 25w-40. My motor is a 454 mag and is 16 years old. Never even had a valve cover off and still runs like a champ.

I'm sure that helps.
Well, I just figure if Mobil-1 "0" weight oil keeps a NASCAR engine alive, the 10-30 is easily gonna keep my big-blocks happy.

The shop changed my oil used 10-30 and i was a little concerned because on mercury's website they said to use a 40w or even a 50w. How long have you been using the 10w30 for?

Well, I put it in at 170 hours and it's at 183 now.
Basically, ask any engine builder, and they will tell you. A bearing doesn't know what the motor is in. Boat, car, truck, stationary pump. A boat motor is under some form of load at all times other than neutral. The better lube you throw at the metal-metal surfaces, the longer it will last.
Straight-weight oil is so "old school". 50's and 60's type stuff. I am real surprised that Merc still recommends that stuff with these "new technology" motors.
