Q8 Mahler G4 SAE 40 Is a medium/low ash gas engine oil.
Medium/low ash gas engine oil
• Gas engine oil for application with natural gas, operating at mild to severe conditions.
• Q8 Mahler G4 was specifically developed with a low deposit tendency and a high resistance against pre-ignition or knocking.
• Q8 Mahler G4 is specifically designed for high pressure gas engines (BMEP: 22 Bar or above), but is also suitable for gas engines with a
• Q8 Mahler G4 can also be used to lubricate reciprocating compressors in which natural gas is compressed and pressures do not exceed
10.000 kPa. Using Q8 Mahler G4 in both the gas engine and the gas compressor will simplify the lubricant inventory.
