Engine Oil

[Hookedup]

I have a 115 Yamaha and a 15 Merc kicker both 4 strokes. I have been using 4 stroke 10w-30 oil. I was wondering if any of you have been using synthetic 10w-30 or regular 10w-30? Any recomendations would be greatly appreciated. Thanks Sean

In my little boat, I run Mobil 1 10W-30 full synthetic. That is in a 40HP Mercury Four Stroke.

I would think that your owner's manual would have some insight as to your oil weight requirements.

Thanks for the info. I went with the synthetic also. Thanks Sean

Sean....if you check back a little you'll see this topic by fishstix. I think that it will answer some of your questions for you.
