Lubricating oil composition
TLDR
In this paper, the authors used a mixture of more than 50 wt % of a Group IIa metal over-based detergent and up to 50 t % of an antioxidant, provided the weight ratio of the mixture to antioxidant lies between 75:1 and 50:1, all parts by weight referring to total active matter of the additive.Abstract:
Lubricating oil compositions suitable for use in marine diesel engines comprise 60 to 85 parts by weight of lubricating oil, 15 to 30 parts by weight of a mixture of more than 50 wt % of a Group IIa metal overbased detergent and up to 50 wt % of a Group Ia metal overbased detergent and 02 to 5 parts by weight of an antioxidant, provided the weight ratio of the overbased detergent mixture to antioxidant lies between 75:1 and 50:1, all parts by weight referring to total active matter of the additive When used in loop-scavenged crosshead marine diesel engines fouling of air ports with deposits is considerably reduced and there is a satisfactory anti-wear performanceread more

Lubricating oil compositions and concentrates
TL;DR: In this paper, the authors described the lubricating oil compositions of internal combustion engines, which include a major amount of oil of lubricating viscosity, and minor amounts of carboxylic derivative composition produced by reacting (B-1) at least one substituted succinic acylating agent with a substituted amine compound characterized by the presence within its structure of at least HN < group.

Method for improving cold flow of fuel oils
TL;DR: In this article, the cold flow of fuel oils is improved by adding esters of addition products of epoxides of specifically limited nitrogen-containing compounds with linear saturated fatty acids or a combination of the esters and polymers of one or more monomers selected from the group consisting of olefins, alkyl esters, and vinyl esters.
