Benefits of Using zMAX

• Measurable fuel and oil savings
• Reduces exhaust stack emissions of black smoke and oil particulates
• Reduced ground pollution from oil puddling
• For new and used locomotives and all fuel types
• Replenish into oil during 92 day inspection
• Results gained through improved combustion efficiency

zMAX Helps Improve Fuel Efficiency in New and Used Engines

• zMAX has proven itself to reduce fuel consumption by an average of 5% in engines.
• Has been time tested over 70 years in both field and laboratory tests.
• zMAX maintains the critical oil film seal between the pistons, rings and cylinder walls resulting in proper combustion sealing (reduced blow-by).
• Proper combustion sealing increases horsepower, reduces and stabilizes fuel and oil consumption.
• Proper combustion sealing reduces oil particulate emissions, black smoke (partially burned fuel) out the exhaust stack and oil puddles from the crank case breather hose.
• zMAX improves lubricity and reduces wear.
• In used engines, zMAX will dissolve and disperse harmful deposits, helping improve and maintain performance.
• In new engines, zMAX will maintain baseline performance throughout the life of the engine.
• zMAX is safe to use in older engines with silver bearings.

Why Use zMAX?

Turbo Chargers

• Increased cooling, reduces deposits and provides better heat dissipation at shut down and helps improve turbo response.

Non-Use and Startup

• zMAX oil film stays in the metal, continuously protecting against corrosion.
• Instant oil film at start up protects surfaces until full lubrication reaches components.
• Beneficial for locomotives in short or long term storage.

Metal Cooling

• Improved heat transfer from zMAX’s micro-lubrication results in cooler surfaces and less thermal distortion.
• Less oil breakdown / better lubricated and cleaner surfaces / viscosity stability.

Less Deposit Build-Up

• Deposits reduce oil flow and the oil’s ability to transfer heat.
• zMAX-treated surfaces stay lubricated so it’s difficult for deposits to form on them.
• zMAX continuously weeps out the metal pores and stays on the metal.

Better Compression

• Results in more efficient combustion
• Improves fuel economy, increases horsepower and lowers emissions.
• zMAX’s ability to cool and lubricate cylinder walls helps keep the critical oil film seal between pistons/rings and cylinder walls.
• Smoother running engine, improved throttle response.

The Tests

Field Tests at Western Short-Line

Comparison of the two oil filters indicates cleaner oil with less deposits using zMAX application.

Field Tests at Southern Short-Line

Two SW1500 locomotives were treated on May 8, 2014 with zMAX into the oil systems.

• At the 92 day inspection period, customer reported a reduction in black smoke on both treated units.
• Oil analysis performed with paper chromatography.
• Results show less soot, which correlates with improved combustion. See photos on next slide.
• Next 92-day test period is currently underway.
