What does it all meanOil Analysis
Wear Metal SourcesIRON=Cylinders,gears,rings,crankshafts,liners,bearings,housings,rods,and platings
Chromium=Rings/roller/taper bearings,rods,platings
Lead=bearing overlays,additives in gear oil and gasoline
Copper=bushings,bearings,thrust washers,friction plates,oil coolers,additive in oil
Tin=bearings,bushings,pistons,platings
Aluminum=pistons,bearings,pumps,blowers,rotors,thrust washers.
Nickel=Valves
Silver=Bearings,bushings,plating
Manganese=trace elements in liners and rings,additives in gasoline
Titanium= trace elements
Vanadium=trace elements
Contents and Sources
Silicon=Element used to determine the level of airborne dirt and abrasives in the oil(Sometimes used as anti-foam agent)
Boron=Present in most anti-freeze systems and cooling systems (sometimes used as an additive)
Sodium=Present in most anti-freeze
Potassium=Present in anti-freeze and cooling systems(sometime used as an additive in gear oil)
Additives and there functions
Magnesium= Dispersant/detergent additive
Calcium=Dispersant/detergent
Barium=Dispersant/detergent additive
Molybdenum=Antiwear
Phosphorus=Anti-wear
Zinc=Anti-wear
Fuel Dilution=Unburned fuel in the oil may signal fuel system leaks or incomplete combustion
Fuel Soot= a result in incomplete combustion or blow by.High drain levels may indicate combustion problems or overextended drain intervals.
Viscosity = The kinematic viscosity determined at 40 degrees C and/or 100 degree C is a measure of the flow rate of an oil in relation to time. This data is used to assign an SAE grade to oil
Sae Grade.....Min CST-100 degrees...Max CST
10w.............4.10...........................xx
20w.............5.60.......................9.29
30w.............9.30.......................12.49
40w.............12.50....................16.29
50w.............16.30....................21.89
So to all of you who does not understand the Metals and Numbers this is for you
