zMAX Delivers Savings on Fuel, Maintenance and Oil Consumption

zMAX treated locomotives are currently operating with dramatic results at several Short-Line Railroads. Check on the tabs below to learn more about What is zMAX?, the Benefits of Using zMAX, Why You Should Use zMAX?, and zMAX Test Results.

What is zMAX?

  • zMAX Micro-lubricant was developed in 1938 to insure positive lubrication for engines during initial start-up, running conditions and non-use.
  • The only product of its kind, zMAX is a pure petroleum product compatible with all motor oils.
  • zMAX molecules have been reformulated smaller than regular engine oil molecules. This allows the zMAX micro-molecules to soak into the metal.

How Does zMAX Work

  • zMAX Micro-lubricant keeps metal surfaces cooler and better lubricated to help fuels and oils do the job they were designed for.
  • zMAX uses the oil as a carrying agent to reach the metal.
  • Penetrates into metal 82x deeper [photo right] than other lubricants (based on Auger Electron Spectroscopy).
  • zMAX penetrates, lubricates, cleans and protects metal from the inside out. There is simply no other product like zMAX micro-lubricant.
  • Disperses varnish, carbon and other harmful performance robbing deposits.
  • zMAX is incorporated into your 92-day locomotive maintenance schedule.

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.

Testimonials

Two GP35 locomotives were treated with zMAX in 2013. Results noted in the first 92-day inspection were overall fuel consumption reduction of 15%; oil consumption reduction 83%; significant reduction in black smoke.
