Best oil for large 4-strokes?

[SaltyJB]

I know that any good quality oil of the proper viscosity, changed regularly, will be OK. But ...

I have read a lot about the advantages of full synthetics (especially AMSOIL) and the multiple advantages of their use. Apparently their advantages extend well beyond the convenince of longer change intervals, and actually contribute to a cleaner burn and marginally better fuel economy. Now the big question: With such greatly extended change interval requirements, would it be wise to get two seasons (figure less than 100 hours/season) out of a change to help offset the significant expense of the synthetic?

No body’s maintenance schedule allows more than one season on Oil changes regardless of what you use

Sludge forms in any oil. Allow it to settle over the off-season and before long you have a layer of sludge that will always mix in with any fresh oil put in over the top of it. Spending the extra dollars for synthetic and then using that as an excuse for improper maintenance is counterproductive no matter how the marketing propagandists twist it.

Amzoil or any other oil supplier does not set the rules for engine maintenance -- the engine manufacturer does. Use what they recommend and change it and the filter at the specified intervals. The same holds true for your car by the way.

Absolutly, even though as most of you know, I`m a BIG Amsoil fan and I do extend the drain intervals on my cars, but an outboard is a different story all together.

Follow the maunufactures recommendations! They don`t hold a lot of oil anyway, so baby her a little.

That's still only $50 bucks per change (Amzoil is $25.00 at my local farm store). If you don't service the engine yourself that figure obviously jumps considerably. Small price to pay for protection of an engine that probably cost well into five figures.
