Selection
A list of approved lubricating oils and lubricating oils allocated to the fuel gas classes can
be found in TI 1000-1109.
The fuel gas quality and possibly the requirements imposed by the exhaust gas after
treatment must be considered when selecting the lubricating oil. Trace and
accompanying elements in fuel gases influence lubricating oil. These are:
• Chlorine, fluorine and Sulphur affect the acidification of the lubricating oil.
• Organic silicon compounds cause wear.
INNIO divides fuel gases into 3 classes:
Class A: Natural gas and gases such as associated petroleum gas, mine gas, biogas (Sulphur
content >100 mg/10 kWh) and special gases such as thermoselect and steelworks gases.
Class B: Biogas, sludge gas, wood gas and pyrolysis gases
Class C: Landfill gas
Purchasing oil
Only those lubricating oils approved by INNIO should be used and purchased from
authorized distributors. The approval process for using non-approved INNIO lubricating
oil can be found in TI 1000-0099A. This oil should NOT be used until approved by the
approving authority.
*Use of non-approved lubricating oil is entirely at the responsibility of the customer!
Storage
At times, the clean oil tank can become contaminated by water condensation or dust or
dirt in the air. To prevent the contamination of these reservoirs, the oil from the clean
tank should be filtered again as it is being pumped into the engines. If this is not
possible, the initial oil drawn from the clean tank should be directed into the dirty oil
tank to remove any settled contaminants before it is pumped into the engines.
The clean oil storage tank should be periodically drained and thoroughly cleaned.
