This will aid you in identifying where each wear metal and element comes from in your machinery such as silicon and aluminium from dirt, aluminium from pistons etc.

Please use these aid memoirs to help you understanding oil analysis data. These are generic information only, as each component metallurgy can vary from OEM to OEM. Likewise, the diagnostic limits will change dependent on not only the manufacturer, but also the operating conditions too, so if in doubt always consult your lab or click the contact us button on the bottom right of the page.
