What brand of oil do you prefer

[Florida Fisherman]

Hi I'm a new boat owner and I'm about to do some maintenance, oil change,sparkplug, lower unit gear oil. What I was wanting to know is which lubricants Yall prefer to use.

All marine FCW oil are pretty much same,
These are what i use
Yamaha / suzuki engine oil- suzuki FCW 10w-40
Yamaha/ suzuki gear lube- mercury high performance gear lube- green color
Fuel water seperator filter canister - yamaha 10 micron filter with stainless steel housing

I have been using Suzuki's 4-cycle marine oil in 10W-40, which is what the boat dealer recommends. However, after reading the owner's manual, it appears that any good quality multi-viscosity oil would be appropriate. So, I am thinking of saving 75% by using the same stuff that I put in my cars. Any reason not to go that route? What does one gain by paying extra for the "FCW" pedigree?

I would use FCW oil, if It is still under warranty, FCW oil has more
Rust inhibitor than regular motor oil
Cars don't rev up to 5,800 rpm and don't sit on the water
that's why. I use FCW oil
