权利要求: T-11864 CLAIMS 1. A marine cylinder lubricating oil composition for a non-carbon based fueled marine engine comprising: (a) a major amount of an oil of lubricating viscosity; and (b) a mixture of overbased phenol-based detergent and overbased calcium sulfonate detergent; and wherein the marine cylinder lubricating oil composition has a TBN of less than 200 mg KOH/g, and further wherein the marine engine lubricating oil composition is a monograde lubricating oil composition meeting the specifications for SAE J300 revised January 2015 requirements for a SAE 20, SAE 30, SAE 40, SAE 50 or SAE 60 monograde lubricating oil. 2. The marine cylinder lubricating oil composition of claim 1, wherein the lubricating oil composition is contaminated with ammonia. 3. The marine cylinder lubricating oil composition of claim 1, wherein the oil of lubricating viscosity is a base oil having greater than or equal to 90% saturates and less than or equal to 0.03% sulfur and have a viscosity index greater than or equal to 120. 4. The marine cylinder lubricating oil composition of claim 1, further comprising an ashless dispersant. 5. The marine cylinder lubricating oil composition of claim 1, further comprising a mixture of phenolic antioxidant and aminic antioxidant. 6. The marine cylinder lubricating oil composition of claim 1, wherein the composition has a BN level of 15 to 80 mg KOH/g.T-11864 7. The marine cylinder lubricating oil composition of claim 1, wherein the phenol- based detergent in an overbased calcium sulfurized phenate. 8. The marine cylinder lubricating oil composition of claim 1, wherein the sulfonate detergent is one or more sulfonate detergents; wherein the TBN contribution from sulfonate detergents to total detergent BN contribution is 20 to 95%. 9. The marine cylinder lubricating oil composition of claim 1, wherein the sulfonate detergent is one or more sulfonate detergents; wherein the sulfonate detergents is present in an amount to provide a sulfonate soap content of 10 mmol/kg to 140 mmol/kg in the lubricating oil composition. 10. A method of lubricating a marine two-stroke engine operated using ammonia fuel, the method comprising lubricating the engine with a lubricating oil composition comprising: (a) a major amount of an oil of lubricating viscosity; and (b) a mixture of an overbased phenol-based detergent and an overbased calcium sulfonate detergent; and wherein the marine cylinder lubricating oil composition has a TBN of less than 200 mg KOH/g, and further wherein the marine engine lubricating oil composition is a monograde lubricating oil composition meeting the specifications for SAE J300 revised January 2015 requirements for a SAE 40, SAE 50 or SAE 60 monograde lubricating oil. 11. The method of claim 10, wherein the oil of lubricating viscosity is a base oil having greater than or equal to 90% saturates and less than or equal to 0.03% sulfur and have a viscosity index greater than or equal to 120.T-11864 12. The method of claim 10, wherein the oil of lubricating viscosity contains greater than or equal to 90% saturates and less than or equal to 0.03 wt. % sulfur. 13. The method of claim 10, wherein the lubricating oil composition has a BN level of 15 to 80 mg KOH/g. 14. The method of claim 10, wherein the lubricating oil composition further comprises an ashless dispersant. 15. The method of claim 10, wherein the lubricating oil composition further comprises a mixture of phenolic antioxidant and aminic antioxidant. 16. The marine cylinder lubricating oil composition of claim 10, wherein the phenol- based detergent in an overbased calcium sulfurized phenate. 17. The marine cylinder lubricating oil composition of claim 10, wherein the sulfonate detergent is one or more sulfonate detergents; wherein the TBN contribution from sulfonate detergents to total detergent BN contribution is 20 to 95%. 18. The marine cylinder lubricating oil composition of claim 10, wherein the sulfonate detergent is one or more sulfonate detergents; wherein the sulfonate detergents is present in an amount to provide a sulfonate soap content of 10 mmol/kg to 140 mmol/kg in the lubricating oil composition. 19. A method of improving or maintaining deposit control performance and/or oxidative stability of an ammonia-fueled marine engine, the method comprising: lubricating the engine with a lubricating oil composition comprising: (a) a major amount of an oil of lubricating viscosity; andT-11864 (b) a mixture of an overbased phenol-based detergent and an overbased calcium sulfonate detergent; and wherein the marine cylinder lubricating oil composition has a TBN of less than 200 mg KOH/g, and further wherein the marine engine lubricating oil composition is a monograde lubricating oil composition meeting the specifications for SAE J300 revised January 2015 requirements for a SAE 40, SAE 50 or SAE 60 monograde lubricating oil. 20.
