    I am wondering if anyone has information about engine oil's vicosity index.
    I am looking for viscosity curve of various engine oil available today
    automobile application. For example, 5W30 oil viscosity at 100 degree C
    compare to 10W30, 10W40 and 20W50.

    Thanks for your help,

    Depending on what you might find elsewhere, a potential source is the
    SAE (Society of Automotive Engineers) Journal. Obviously, they are
    *not* in the business of responding to the needs of the general
    population, but if you hit up your local library they may have (a big
    one) or have system access to (average size) the journal. Most
    libraries today do have the computer access to a host of technical
    publications and, often, actually have the articles on-line.
