Diesel Engine Cylinder Oil
Mobilgard L540 by ExxonMobil is a superior quality, extra high performance
marine diesel engine cylinder oil. This unique formulation has been
specifically developed for engines running in a low sulphur heavy fuel oil
(HFO) environment. This cylinder lubricant provides maximum protection from
adhesive and corrosive wear at the higher operating temperatures and pressures
of today's modern crosshead engines, for maximum reliability. It employs
additives with greater therrmal stability and superior acid-corrosion
protection. It has an optimum viscosity of over 20 cSt. at 100ºC and low
volatility for best lubricant distribution and film retention. Through the use
of unique formulation technology, the higher viscosity is attained with little
or no use of thermally less stable, deposit-producing bright stock. Advanced
technology at the 40 TBN alkalinity level in Mobilgard L540 has demonstrated
excellent ring and liner wear protection and cleanliness under sustained
operation with fuel sulphur levels from less than 0.3% up to 1.5%.
Mobilgard L540 cylinder oil offers the following features and potential
Mobilgard L540 has been developed for marine crosshead engines with increased
power and fuel efficiency. Such engines exhibit higher temperatures and
pressures in the cylinder, which reduce the lubricant's viscosity and increase
the loads which it must withstand. Longer piston strokes have greatly
increased the amount of surface to be protected and the amount of time the
lubricant must withstand the severe cylinder temperatures and corrosive
sulphur acids. Mobilgard L540 has also demonstrated superior performance in
earlier engine designs.To ensure achieving the maximum
equipment life possible, particular attention should be paid to the
manufacturer's special recommendations regarding the running-in of new rings
and liners.Mobilgard L540 was specially formulated for use
in applications with fuel sulphur levels ranging from less than 0.3% up to
1.5%. Applications where the sulphur level is above 1.5% require special
consideration and should be discussed with your ExxonMobil representative.
Appropriate feed rates should be verified in all cases by through-the-ports
inspection of liners to ensure adequate oil film.
