Funny thing..... Rotella is not FCW rated
I recall seeing similar pix advertizing various brands of synthetic oil. And most people may be over-thinking this, just use what the manufacturer recommended, if you have a Merc use the Merc stuff, who cares if it costs more you only change once a year. If Volvo, yeah the syn straight 30 is hard to find and expensive, but still you do it once a season, just use what they say, I usually don't second guess engineers. As for me, I use what OMC recommended, straight 30, and even when I have started it as cold as 45* it still starts fine. I'm not boating when it's below 65 anyway! I do think for most people boating, using a straight weight with no VI improvers does help things since deposits from them can cause trouble and a multi vis oil still tends to shear down more than a straight weight, which is probably why, Volvo recommends straight 30 and the Merc oil is really not a true multi vis but a combination of 2 straight weights.
that pic is why I like a 2 stroke snow blower with electric start, no probs starting at the coldest temps (we only get to zero here once in a while), except for the nice big blue smoke cloud at start up!
