Some use "marine" grade while others do not

Some use Valvoline strait 50 weigh "racing" oil

Marine grade oils are formulated for a damp environment. Not a bad
idea.

How does a marine grade better protect in on the water than a standard
grade?



Using a straight weight oil in warm climates is probably preferable to
a multi viscosity oil.

Volvo Penta recommends a SAE 15W-50 API SG multigrade (natural or
synthetic). I had always thought a straight 30W was preferable.

What are your thoughts Gene?


What is your "I had always thought" based on?
