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:

Features                                                       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

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 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.
