Driven racing oils. They also put out by far the most education about oils and it is not sales pitches about their own oils. IMO they do a really good job on both ends of the coin. Oil products and educating the end users.

I think this time I'll just use the regular Merc stuff through the winter. Then, I'll reconsider changing in May when I change the oil again. Thanks for all the replies!

The synthetic blend is rated FC-W. Is there any advantage to using one or the other? I'm in SW Florida, so, boating season is still on and typically 70-80 degrees this time of year. The water temp is usually in the 60's & 70's now (not to rub it in with the northern readers, but just to know what the conditions that the boat is operating in).

FC-W is the NMMA rating for 4-cycle water cooled marine engines.

Why both oils are not NMMA FC-W rated I don't know. But a lot of people, myself included do not use a NMMA FC-W rated product or even a NMMA rated product.

Personally I been using synthetic oil in all my vehicles and boats forever. Just can't go wrong with synthetic! Not sure if the FW has an advantage in salt water areas or not?

I had the graphic. Can't find it now, but the synthetic blend is the #1 to buy, #2 would be the 'regular' 25w40.

The price difference seems low enough they should just drop the 'regular' one.
