engine oil to achieve the maximum life and performance in Caterpillar marine engines. CXP diesel engine oil has been specially formulated and tested to minimize piston and ring deposits. These harmful depos- its can lead to premature wear and premature failures. To maximize marine transmission life and performance, it is now rec- ommended to use Caterpillar's CXP transmission/drive train oil. This oil has also been specially formulated to minimize internal wear. Caterpillar's goal has been and remains to significantly improve the performance and durability of Cat- erpillar marine products. Caterpil- lar wants to insure that its custom- ers get every hour out of their Cater- pillar engine that was originally de- signed into the engine. CHEVRON Circle 40 on Reader Service Card Chevron has recently introduced Chevron DELO Marine Oil 477 for the inland marine trade class. It is marketed as Chevron DELO 6170 Oil for customers on the western and eastern seaboard. Chevron's DELO Marine Oil 477 (DELO 6170 Oil) is test proven, demonstrating superior results in the field for today's new generation high-performance diesel engines. This product is designed especially for use in engines for towboat ser- vice where some current lubricants may have limited performance and is compounded to a high alkalinity level, measuring 17 TBN (Total Base Number) by ASTM Method D-2896. New engine designs require im- proved oxidation and viscosity con- trol for operating demands of fuel efficient engines with higher com- bustion pressures and tempera- tures. Increased alkalinity reserve is required for corrosive wear protec- tion and especially for operations requiring extended drain intervals. DELO Marine Oil 477 (DELO 6170 Oil) was field tested in marine and locomotive service in GE and EMD engines with full approval from these engine manufacturers. Field testing demonstrated in- creased oxidation and viscosity con- trol compared to typical Generation 4 lubricants. This increased oil con- trol can allow increased drain inter- vals for GE engines and due to increased drain intervals, the added alkalinity reserve also provides the ability to extend drain intervals. This superior oxidation stability and viscosity control was also demonstrated in EMD engines modified to run at higher operating temperatures to increase efficiency. Chevron DELO Marine Oil 477 (DELO 6170 Oil) provides an op- timized engine oil formulation for today's service requirements for in- dustrial engine design in marine towboat and ferry service. CUMMINS Circle 36 on Reader Service Card Cummins Engine Company, Inc., Columbus, Ind., offers Premium Blue engine oil for the marine market. The company reports that Premium Blue 15W-40 oil has spe- cially formulated additives selected to maximize the performance of heavy-duty diesel engines. Since engine oils are mostly base oil stocks, it is the chemical additive package blended into these base stocks that are the key to oil per- formance. Cummins spent eight years in the lab formulating Premi- um Blue to optimize performance in their engines. The additives in Premium Blue include materials that modify base stock characteristics with respect to such factors as viscosity, detergen- cy, dispersancy, wear, oxidation, corrosion, pour point and foam. SAE Viscosity Grade 15W-40 Premium Blue has a pour point of -30 degrees C, viscosity of 3200 cP at -15 degrees C and 3.6 cP at 150 degrees C. The company reports that Premi- um Blue is specially formulated to prevent carbon build-up, which is critical to low oil consumption. Pre- mium Blue contains high concentra- tions of detergents, dispersents and oxidation inhibitors to reduce the rate of formation of deposit-forming materials. Those materials that do form are suspended in the oil so that they can be removed from the en- gine when the oil is drained. Also included are anti-wear addi- Cavitation DuraTougti—the only product that resists cavitation erosion 5 times better than carbon steel.

Removing dirt from your engine's lubrication system is the key to reducing engine wear and lowering your maintenance costs. That's what the Spinner II centrifuge does, efficiently and economically. Typical full-flow lube-oil filters trap dirt particles down to only about 40 microns in size. However, parts like piston rings can squeeze the oil film as thin as one micron. Remove the microscopic particles and you can reduce engine wear by half or better. To do that requires a centrifuge. Until now, a centrifuge meant investing in an expensive, electric-motor-driven machine. Now there's the Spinner II cen- trifuge, a self-contained, high-speed unit driven only by oil pressure. It removes abrasive grit as small as one-tenth of a micron for a low cost you can justify! The complete line of Spinner II centrifuges protects all marine diesel engines.
