I have ridden that area many times, mostly the northern portions of Lake St. Clair and the river delta areas around Harsen’s Island.

YamaLube 4W oil will be just fine.

We ride in a wide range of air and water temperatures. As far north as Red Lake, Ontario and around Lake Superior, and as far south as the Gulf of Mexico, Florida panhandle. One is about 3,000Km farther north than the other.

Always using YamaLube 4W. About 340 hours now on each SVHO engine.
New Motorcraft FL400S oil filter with each oil change.
