Mobilgard 570

Diesel Engine Cylinder Oil

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 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. 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 1.5%, but in some cases can be used in lower sulphur applications with the approval of the engine manufacturer.

Features and Benefits

Mobilgard 570 cylinder oil offers the following features and potential benefits:


Advantages and Potential Benefits

Excellent thermal and oxidation stability

Reduced deposits and sludge formation

Cleaner engine reduces lay-up time required for overhauls

Exceptional antiwear properties

Reduced liner and ring wear

Excellent anti-scuffing control

Outstanding detergency capability

Superior piston and liner cleanliness increases combustion efficiency and extends periods between piston overhauls

High TBN level and retention

Wide fuel sulphur capability

Minimises the corrosive effect of high sulphur fuel combustion


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 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.

Applications where the sulphur level is below 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 for adequate oil film.
