Syntetic oil has better corrosion protection than petroleum oil. One of its advantages is that it doesn't emulsifiy easily. Volvo uses syntetic oil in marine, industrial and automotive engines. So does GM, Caterpillar and many others. Where do you get the facts to compare oils from? I read the manufacturers data. If it was true what you say about syntetics it would void the warranty. However, it doesn't. All studies show that syntetic is superior in every respect.
