Marine Oil vs Auto Oil

Is there really a difference between marine 10w40 and auto 10w40? Never really thought of using a specific marine oil for my boat before...

Re: Marine Oil vs Auto Oil

For my small boat I run Mercury's Quciksilver 25W40 Synthetic oil.
It costs more but sure beats issues with the oil thinning out on hot summer days.
You can use regular automotive oil in the boat but I stick with the Merc oil for peace of mind.
The bigger boat I let the dealer service it so I have no idea what type oil they stick in the Verado's.

Re: Marine Oil vs Auto Oil

I asked the same question somewhere else recently and someone brought up a good point.. I run my jet around 45-5500 rpms.. Cars don't cruise that high.. It costs me an extra $30 to use the Yamaha oil but I don't want to risk it

Re: Marine Oil vs Auto Oil

its very high quality synthetic, is it different, hard to say, good one for the boat shop mechanic.

Other thing to think about most recommend 100-200 hours between changes. i believe my Yam 115 is 200 hours in the manual. I fish a ton and only run about 75 hours a year. I still change it usually once per season. So for only one change its worth the extra cost i would say.

I was told the difference is because boats are could with water and cars are colded with antifreeze. They run at different temperatures.
