| Element Analysis Information | |
| Element | Possible Sources |
| Iron | Indicates wear originating from rings, shafts, gears, valve train, cylinder walls, and pistons in some engines. |
| Chromium | Primary sources are chromed parts such as rings, liners, etc. and some coolant additives. |
| Nickel | Secondary indicator of wear from certain types of bearings, shafts, valves and valve guides. |
| Aluminum | Indicates wear of pistons, rod bearings and certain types of bushings. |
| Lead | In diesel engines, from overlay of most rod & main bearings. In gas engines, mostly from tetraethyl lead contamination. |
| Copper | Wear from bearings, rocker arm bushings, wrist pin bushings, thrust washers, other bronze and brass parts. |
| Tin | Indicated wear from bearings when babbit overlays are used. Also an indicator of piston wear. |
| Silver | Wear of bearings which contain silver. Also a secondary indicator of oil cooler problems. |
| Titanium | Alloy in high quality steel for gears and bearings. |
| Silicone (Dirt) | Airborne dust & dirt contamination usually suggesting air filter service needed. Excessive contaminates can greatly accelerate component wear. |
| Boron | Coolant additive, used as a oil additive. |
| Sodium | Coolant additive, used as a oil additive. |
| Potassium | Coolant additive. |
| Molybdenum | Indicates ring wear. Used as a additive in some oils. |
| Phosphorus | Antirust agent, spark plug & combustion chamber deposit reducer. |
| Zinc | Antioxidant, corrosion inhibitor, anti-wear additive, detergent, extreme pressure additive. |
| Calcium | Detergents, dispersants, acid neutralizer. |
| Barium | Corrosion inhibitor, detergents, rust inhibitor. |
| Magnesium | Dispersant, detergent additive, alloying metal. |
| Antimony | Bearing overlay alloy or oil additive. |
| Vanadium | Heavy fuel contaminant. |
| Viscosity | Measures a lubricants resistance to flow. |
| Glycol | Positive test results indicate a problem associated with cooling system internal leaks |
| Fuel Dilution % Vol. | Indicates the amount of unburned fuel in the engine lubricant. |
