Ask Tyler what he reccomends... I use 15-50 M1 and In general I would say you cant go wrong with it, the 20-50 V-twin seems to be popular also but is on the expensive side at 7+ / quart..

Amsoil, change every 25-30 hours.

He recomened the Mobil 1 15/50- I didnt ask but I would assume its a sunthetic - I Just want the input form all you other boaters to see if its a good choice.

Yes !!

Mobil 1 goes in everything I own.

I have a shop truck that just turned 400K. '96 350 Chev. Never as much as had the valve cover off of it. Uses about a quart in 5K. I change every 10K.

Rotella T 15-40 in flat tappet boat engines and 2006 PSD. I had trouble with cams before this when running M1 15-50. This will now be the third season with these engines and running rotella. If you have oil temps that exceed 250f as an upper limit, use the synthetic rotella.
