Mobilgard 570

Product Description

Mobilgard 570 by ExxonMobil is a superior quality, extra high performance, marine diesel engine cylinder oil. This bold new approach in cylinder lubricant technology provides maximum protection from adhesive and corrosive wear at the higher operating temperatures and pressures of today’s modern crosshead engines. The outstanding performance of Mobilgard 570 has been demonstrated at the highest peak firing pressures and liner temperatures.

Mobilgard 570 employs additives with substantially greater thermal stability and superior acid-corrosion protection. It has an optimum viscosity of 21 cSt. at 100ºC for best lubricant distribution and film retention. Through the use of unique formulation technology, this higher viscosity is attained with little or no use of thermally less stable, deposit-producing bright stock. Unique technology at the 70 TBN alkalinity level in Mobilgard 570 has demonstrated superior ring and liner protection and cleanliness under sustained operation with fuel sulphur levels down to

۱٫۵%, but in some cases can be used in lower sulphur application with the approval of the engine manufacturer.

Applications

Mobilgard 570 has been developed for marine crosshead engines designed for 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 570 performance has also demonstrated superior protection 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. Consult your ExxonMobil Marine Lubricants Representative for assistance and recommendations for run-in.

Appropriate feed rates should be verified in all cases by through-the-ports inspection of liners for adequate oil film.

MOBILGARD 570 is manufactured from high quality petroleum base stocks, carefully blended with selected additives. As with all petroleum products, good personal hygiene and careful handling should always be practiced. Avoid prolonged contact to skin, splashing into the eyes, ingestion or vapour inhalation. Please refer to our Imperial Oil Material Safety Data Sheet for further information.
