Mobil™ Pegasus™ 605 Ultra 40 is a gas engine oil primarily intended
for the lubrication of modern medium and high-speed four-cycle
engines operating on landfill gas that contains contaminants such
as hydrogen sulphide, halides or siloxane. Its formulation has been
carefully balanced to provide extended oil drain intervals, control
the formation of carbon and varnish deposits, with very good anti-
wear and anti-scuff performance.
