SO what do I use.

First time boat owner and I want change my oil.

I'm getting conflicting recommendations on what to use.

I have a 1986 Ford 351 Windsor:
The owner's manual calls for 10W 30 or 10W 40.
The dealer tells me to use 15W 40 Penzoil Marine Oil.
Another dealer tells me to use 25W 40.

What do I use!?!?!?!

Thanks.

There are lots of opinions about oil on this forum. I have an '87 351 and not to add to your confusion I use Valvoline VR-1 20W-50. You would be fine with either of the oils recommended in the owners manual.

+1. Whatever you use, get something that has not suffered the reduction in ZDDP.

I also run the 20W50 VR-1 for my flat tappet Ford.

Sounds like I'm buying the VR-1. Thanks guys!

I love this place. I hope someday I can be a contributer, and not just thread sucking questioning member.

CBRENT is this to get the water out of your oil that you posted in another thread. If you are going to be making multiple oil changes to get the water out of your engine or determine the source of the water you may want to use a cheaper oil while doing that.

X2 that do not use expensive oil for this....Use VR-1 for your final after all AGUA is gone!

For sure guys. I just wanted to know what to put in after I was done with the water issue.

I pulled the boat out last night and drained the oil, gave it an hour and a half to drain. The initial oil that came out looked good, but then turned to caramel minutes later. I put new oil in, plan on putting her back in the water tonight for a quick test and see if there is still any water left.

Will I get results immediately or no?

Depends on how fast the leak is. Mine started at about the ten minute mark, then got quickly worse. Made it real easy to find. Good luck.
