Update on AMSOIL MCF, Motorcycle 10w-40, in 2011 Bravo X drives with new Merc 502's in front of them. So far, about 25 hours, pulled one top cap, and gears are perfect!!! In that duration, one poker run, and some decently longer runs around the lake. Boat will run 91.7 GPS, so....

It all depends on what Brand of oil you are selling, in what is the best. It's all an opinion, period.
Never have I had a drive fail because of oil, if I'm using the right product. Mercury has more test time on oil when it comes to out drives and outboard lowers than anyone in the industry. In all my 45 years with the Mercury Outdrives, have I had a drive failure because of oil. And I have 15 World Titles under my belt. It's not about just oil, it's how the gears and bearings are set according to the HP. Gear setting is the most important. No matter what. But everyone out there tends to always blame the oil first. I guess that's the easy way out.

Did your boat slow down from the thicker oil? When I was doing extensive lower gear testing a few years back I found the 85/140 Royal purple slowed my boat down about 4%, In testing that was almost back to back boat ran 92-93 with 80/90 and wouldn't break 88-89 mph with the thick stuff(I had less power then than now), being supercharged with a inner-cooler boat pretty much runs the same number too regardless of weather conditions on typical Mi days unless air is really good with low ambient temp, Smitty
