for Mercury four stroke 10w-30 motor oil? I have been to several stores in the area and all they have is two stroke oil or 25w-40 four stroke oil for sterndrives.
I would like to find a suitable substitute available locally (preferably synthetic) since the Mercury oil is so hard to find.
Valvoline 10W30 full synthetic
regular automotive oil?Quote:

Now I just have to find some.
I finally found some oil at West Marine (BPS and Boater's World were out). I noticed they have their own brand in the certified FC-W list. They actually had Mercury oil in the viscosity I wanted as well. I chose the Mercury oil over their own brand but it is nice to know I have some options.
Now go pick up a bottle of the Valvoline synthetic and compare it's specs to the Mercury oil.
I'm sure Valvoline Synthetic is good oil but nothing that is not NMMA certified FC-W goes in my outboard.
If some of the automotive oils want to certify, I'll be glad to use them.
I have used Pennzoil Marine 4 stroke 10w30 in my Mercury 4 stroke the last 2 times I changed my oil and have had no problems,got it at Walmart.
LMAO! Well then why did you askQuote:

"Marine rated" is a marketing gimmick much like the "trail rated" Jeeps a few years back.
I'm sorry I even tried to answer your question. It's clear your logic is flawed. But hey, it's your money and the marketers have you convinced.
