Oil Analyzers Test Kit
The first thing you'll need to do is purchase an Oil Analyzers Kit, which is available three basic ways for gasoline-powered Mustangs.

KIT01 with pre-paid USPS postage $24.99
KIT02 (KIT401 in Canada) with UPS pre-paid $25.75 (Higher in Canada)
KIT06 (KIT 402 in Canada) with non postage paid $17.95 (Higher in Canada)

There's also a coolant test kit available (KIT09 US and KIT403 in Canada) for a good look at your Mustang's coolant properties.

What You Can Learn from Oil Analysis
Gasoline in the oil: Reduces the oil's lubricity. Unacceptable amounts of gasoline from a poorly tuned carburetor or faulty fuel injection system wash oil off cylinder walls and hinder lubrication.

Viscosity or oil density: Indicates a lubricant's ability to flow based on temperature and oxidation. Oil gets thicker when cold and with oxidation.

Antifreeze in the oil: Causes oil to turn into a thick, brown substance, which hurts lubricity. Will cause engine damage if not corrected. Antifreeze in the oil raises sodium content in the oil.

Oil oxidation: A measure of contaminants in the oil, such as gum and varnish from fuel and excessive heat. When the engine overheats, it will cause excessive oxidation in the oil. Blow-by from worn piston rings and excessive piston-to-cylinder wall clearances also causes oxidation.

The Total Base Number: Shows acid reducing capacity of the oil.

Total Solids: Shows ash, carbon, and lead salts from gasoline and oil oxidation.

Sodium Levels: Detects coolant levels in the oil due to an internal coolant leak.

Silicon Levels: Indicates sand or dirt in the oil, which comes from poor air filtration or inadequate crankcase ventilation. If you live in a dry, dusty desert environment, don't be surprised if silicon levels are high.

Nitrate Levels: High amount indicates excessive piston and ring blow-by from wear.

Lead Content: High levels come from the use of leaded gasoline or octane enhancers. Some unhealthy engine wear patterns will yield high levels of lead.

Iron Levels: Many sources, including crankshaft, connecting rods, cylinder walls, main bearing caps, cylinder sleeves (where equipped), camshafts, timing sprockets, and more.

Copper Levels: Abnormal wear in bearings, bushings, valveguides, and shims. If you find excessive amounts of copper, you have abnormal engine wear.

Aluminum Levels: Indicates wear patterns with aluminum engine components, like piston skirts and ring grooves, bearings, thrust bushings, timing sprockets, and oil pumps.

Chromium Levels: Mainly from chrome moly piston rings or certain types of oil additives. Chromium also comes from airborne particles ingested via air cleaner or crankcase ventilation.

Boron Levels: Oil additive found in engine oil or an oil additive.

Other Metals, such as Calcium, Magnesium, Barium, Zinc, and Phosphorous: Also found in engine oil and additives. These metallic additives are normal and no cause for alarm unless levels are extremely high.
