    Did you know that in order to burn off water vapor, your engine oil should be between 230-260 degrees (F). If it were 212 degrees, or less, the water vapor would combine with sulfur to create harmful acids. As a side note, synthetic oil is rated up to 300 degrees.

    So run synthetic is a bad idea?

    I run synthetic in all my vehicles. wife's Grand Cherokee , my ram, and even my 2009 Rt (Mobil 1 in that one. the rest of them are Pennzoil. usually change oil when they get down to 50% or about every 4-5000 miles.

    No, synthetic oil is preferable to conventional oil for a lot of reasons, such as: keeps parts cleaner, better wear protection, better flow in low temperatures, better protection at high temperatures, protects turbo parts, and has longevity.

    As an oil formulator and having conducted multiple field tests on mineral and synthetic oils under extreme conditions, I can say that there is no real benefit for synthetic base oil over the now common hydroprocessed conventional base oil. They both pass a very severe ASTM Sequence III-G engine test that stresses the oil at 300°F for 100 hours measuring viscosity increase, oxidation stability, oil consumption, wear, piston deposits and engine cleanliness. All modern oils pass the same test, and I have seen synthetic oils show more deposits in this test than mineral oils, so I don't believe there are benefits to synthetic oils in all but the most extreme conditions. And these are very low temperature extremes, not high temperature extremes. Below -40°F, a synthetic oil may (and I mean MAY) pump quicker than a mineral oil, but that is the only realistic benefit of a synthetic base oil. The rest of the performance of an oil in and engine is due to the additive package used, and this is dictated by passing ASTM Sequence Tests which really do stress the oil.
    The rest is advertising hype.
