Castrol Magnatec

[Suzie Chaser]

I run my Yamaha f 200 xb mostly in cold weather during duck season. After seeing a few commercials on tv about the new castrol Magnatec oil, the marketing strategy is that engine wear is occurs mostly while the engine is cold.
Most of the time we crank up at the landing and haul ..... In freezing conditions.
So my question is , has anyone tried the new Magnatec oil in any four stroke outboards ?
Thanks

If it is a marine oil use it, if not stay away from it, marine oils have rust inhibitors and other additives for a wet environment .

if its not rated FCW don't use it.
never seen a fourstroke with lack of oil wear.

if your that nervous simply add crankcase store-n-start at each oil change.

most manufacturers say to let the motor warm up before hauling A$$
