Product Description 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 acidcorrosion 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, depositproducing 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%. Features & Benefits Mobilgard L540 cylinder oil offers the following features and potential benefits: Applications 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.
