Logas 6.6

Logas 6.6 is an engine oil specially developed for the lubrication of gas engines running on BIOGAS or LANDFILL gas. Biogas and landfill gas contain higher levels of hydrogen sulfide (H2S) than natural gas, so they have a much more corrosive character.
The selection of highly refined mineral base oils and specific additives ensure Unil Logas 6.6 has a very good TBN retention. As a result, acids formed during the combustion process are neutralized.
The optimal protection by avoiding deposits on the various engine components (valves, valve seats, cylinder, ...) will ensure that your installation works at the highest efficiency rates.
Furthermore, Unil Logas 6.6 is high oxidation resistant and thermal stable which is beneficial to the lifetime of the oil, as a result this oil can be used for extended drain intervals.


  • Ideal for engine that run under constant high load and at higher temperatures.
  • Very good TBNT erexttee1n1t:ion to neutralize acidic components
