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.
