SOS Fluid Analysis Results

S•O•S Fluid Analysis

Listed below are generic examples of how an oil condition report can be an indicator of what is going on inside of your fluid filled components.

Diesel Engine Oil

Iron, chrome, aluminum, lead, sodium, potassium, copper, silicon, and soot are some of the key elements used to determine the condition of your engine. Different combinations of these elements indicate what’s wearing.

Iron & chrome indicate cylinder line and piston ring wear, add aluminum and you have evidence of piston wear also.

Lead, aluminum, and iron are the result of rod and main bearings and crankshaft wear.

If sodium, potassium, and copper are found in the same sample, it indicates coolant contamination.

Silicone, greater than aluminum, with iron and lead tells us that dirt is entering the engine and causing the wear on liners, rings, pistons, and bearings.

Soot, iron, lead, and chrome can indicate wear from soot on liners, rings, and bearings.

Powershift Transmission 


Silicone and iron in combination indicate wet clutch friction material and separator plate wear

Aluminum, copper, and iron come from the torque converter

Copper, greater than lead or tin indicate bronze bearing or thrust washer wear.

Hydraulic

Iron and chrome together indicate cylinder and rod wear.

Silicone, greater than aluminum, with iron and chrome tell a story of dirt entry, pump wear, and cylinder and rod wear.

Axles and Final Drives

Silicone, greater than aluminum, with iron, chrome, and nickel, indicate dirt entry, gear, and bearing wear.

Copper, greater than lead or tin, indicates bronze bushing or thrust washer wear.
