Sulphated ash level The content of sulphated ash in gas engine lubricating oils is a very important property. Too high ash content can cause preignition, knocking and spark plug fouling, while too low ash content can lead to increased valve wear. Low ash lubricating oils with sulphated ash level of max. 0,6 % m/m have to be used. Additives The oils shall contain additives that give good oxidation stability, corrosion protection, load carrying capacity, neutralisation of acid combustion and oxidation residues and should prevent deposit formation on internal engine parts. Foaming characteristics Fresh lubricating oil shall meet the following limits for foaming tendency and stability, according to the ASTM D 892-92 test method: Sequence I: Sequence II: Sequence III: 100/0 ml 100/0 ml 100/0 ml Base oils Use of virgin base stocks is only allowed, i.e. recycled or re-refined base oils are not allowed.

Otherwise the lubricating oil system has to be drained and then filled with another brand by following the procedure described here below. In order to minimize the risk of lubricating oil foaming, deposit formation, blocking of lubricating oil filters, damage of engine components, etc., the following procedure should be followed when lubricating oil brand is changed from one to another: If possible, change the lubricating oil brand in connection with an engine (piston) overhaul Drain old lubricating oil from the lubricating oil system Clean the lubricating oil system in case of an excessive amount of deposits on the surfaces of engine components, like crankcase, camshaft compartment, etc. Fill the lubricating oil system with fresh lubricating oil If the procedure described above is not followed, responsibility of possible damage and malfunctions caused by lubricating oil change should always be agreed between the oil company and customer.

In some cases also longer change intervals may be achieved by using API Gp II or IV based products.

Page 4 (4) Document No 4V92A0780 Rev k USE OF NON-VALIDATED LUBRICATING OILS: Before using a lubricating oil not listed in the tables above, the engine manufacturer must be contacted. Lubricating oils that are not validated have to be tested according to engine manufacturer s procedure. Should a non-validated lubricating oil be used during the engine warranty period, and there exist no agreement with the engine manufacturer about testing, the engine guarantee does not hold. Lubricating oil companies listed above along with other possible manufacturers and distributors undertake all responsibility for the performance of their validated lubricating oils in service to the exclusion of any liability of any Wärtsilä company belonging to Wärtsilä group. Further, they shall indemnify, compensate and hold harmless Wärtsilä and companies belonging to Wärtsilä group from and against any claims, damages and losses caused by the lubricating oils in question. LUBRICATING OILS FOR ENGINE TURNING DEVICE Based on the turning device manufacturer s instructions EP-gear oils having viscosity of 414-506 cst at 40 C = ISO VG 460 are normally considered as suitable lubricating oils for turning device.
