    Introducing Castrol EDGE, the Ultimate in Wear Protection with 8x better wear protection than Mobil 1.*

    Castrol Edge is an advanced full-synthetic motor oil with unsurpassed wear protection, based on an industry-standard Sequence IVA test.*

    The test measures how effective an oil is at performing its most basic function -- protecting your engine against wear. After 100 hours, the results were clear. No other synthetic motor oil could beat Castrol Edge.*
    And that's a fact.

    Shouldn't you upgrade?

    *5W-30s tested in industry standard Sequence IVA wear test.
