Premium quality, medium ash, dispersant/detergent type gas engine oil formulated especially for four stroke landfill gas applications.  Combination of high performance hydrocracked base fluids and a robust inhibitor package provides exceptional protection and maximized oil drain intervals even in the presence of the most aggressive landfill gases.


APPLICATIONS

• Four-stroke engines fuelled by landfill gas containing elevated levels of chlorofluorocarbons (CFCs).
• Sour gas applications where corrosive wear is a special concern.
• Engines where an increased ash level is preferred for improved valve recession control.
• Sweet gas applications where a higher base number is preferred.


BENEFITS

Maximizes oil service life
Combination of high performance hydrocracked base fluids and specially balanced oxidation inhibitor package and dispersant provides outstanding oxidation and nitration resistance in conventional sweet gas applications and more arduous landfill applications.

Lowers operating costs
Excellent deposit control on valves and pistons reduces oil consumption.  The exceptional oxidation and nitration resistance and deposit control extends oil drain capability so that equipment is in service longer generating revenue.

Minimizes maintenance costs
Exceptional oxidation resistance and dispersancy minimizes sludge formation, avoids filter plugging, cylinder head sludge, abrasive polishing wear and oil thickening. Special formulation gives excellent corrosion control in engines burning high CFC and / or high sulfur containing fuels where high levels of acidic condensate form.  This exceptional corrosion control ensures maximum liner life even in intermittent operation.  Valve recession is controlled over low ash formulations in those engines where medium ash oils are preferred.

Extends engine life to overhaul
High level of anti-wear additive protects against valve train wear and scuffing of highly loaded parts operating under boundary lubrication conditions.  Level and type of ash producing additives reduce valve recession. and potential for pre-ignition.

SERVICE CONSIDERATIONS


Fuel pre-treatment is generally necessary to make landfill gas suitable for reciprocating engines. Used oil analysis (UOA) will permit oil drain intervals to be adjusted as required to accommodate variances in fuel composition.  Additionally, used oil analysis is necessary for new engines to ensure results are kept within the warranty protection limits set by the equipment manufacturer.

As with all gas fuelled, spark ignition engine applications, the choice of lubricant ash level will be a trade-off between prevention of exhaust valve recession, prevention of exhaust valve distress and preignition, and provision of adequate alkalinity reserve.


ENVIRONMENT, HEALTH AND SAFETY
