Re: Wal-mart Outboard Motor Oil
You'll get a variety of opinions on this. If it's rated TCW3, it means it meets at least the minimum requirements. Personnally, I believe if I had a brand new Mercury, I'd use Quicksilver as recommended by the manufacturer. It may or may not be any better than Walmart; I don't know. But if you ever have any problems under warranty, it would be better to be able to say you've used what Mercury recommended. In the scheme of things, oil is a pretty cheap part of boating, anyway. Just my opinion.
