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 post a question to the site.
Bite Size Diagnosis – Engine oils.
Bite Size Diagnosis – Gear / Axle oils.
Bite Size Diagnosis – Hydraulics and compressors
Bite Size Diagnosis – Steam / Gas Turbines
Bite Size Diagnosis – Automatic transmission Fluids
Bite Size Diagnosis – Cylinder oil scapedowns.
