teristics, improved spreadability, tenacious film retention, and to minimize port and piston deposits. Because of its high alkalinity (70 Total Base Number or TBN), it pro- vides better protection against cor- rosive wear by neutralizing large amounts of strong acids. This oil is compatible with oils normally used in the crankcase of crosshead en- gines. Mobilgard 300 system oil was also developed especially for modern, high-output, crosshead type marine diesel engines. It is formulated from highly treated paraffinic base oils that are selected for their thermal stability and oxidation resistance. The inherent base oil characteristics are augmented with a balanced ad- ditive package including high-tem- perature oxidation inhibitors, alkal- ine detergent-dispersants, and de- foamants. The formulation has maximum antiwear properties, good rust protection in the presence of salt water, and excellent water sepa- ration characteristics. The Mobilgard 24 series oils were developed originally to meet the re- quirements of medium-speed, trunk piston diesels used for main propul- sion engines on coastal and river vessels. The series was reformulated recently to provide improved per- formance in the new, higher-output versions of these engines now com- ing into service. The Mobilgard 42 series of ma- rine lubricating oils has been devel- oped to supplement the Mobilgard 24 series (30 TBN) oils for the lubri- cation of modern high-output, me- dium-speed trunk diesel engines used in oceangoing vessels and fer- ries. Mobilgard 42 oils have an alkalin- ity level of 40 TBN and are there- fore particularly suitable for engines that show indication of corrosive wear to cylinder liners and piston rings. Mobilgard SHC 120 is a 12 TBN synthetic, medium-speed diesel lu- bricant. It contains a balanced blend of synthesized hydrocarbons and ester-based fluids, with an addi- tive system designed to provide op- timum performance in diesel en- gines. Although its measured viscos- ity indicates that it is an SAE 40 grade, this oil's inherent high index enables it to perform similar to an SAE 15W-40 viscosity grade diesel engine lubricant. It is formulated for operation in extremes of am- bient temperature. The Mobilgard 12 series oils are intended for marine diesels operat- ing in distillate fuels or light fuel blends. These oils have proven espe- cially effective in small-bore, high- speed trunk engines and automo- tive-type diesels used in fishing fleets, the new severe service en- SHIPBUILDERS If you're looking for a fast labor saving system to drill precision holes for fitted bolts that is extremely accurate (and portable) and met U.S. NAVY requirements on L.S.D.'s 41, 42, & 43.
