A drainage bag system for urinary collection includes a urinary drainage bag having a first inlet and an inlet valve for regulating a flow of urine from a catheter into the urinary drainage bag via the first inlet, an outlet, and an outlet valve for regulating a flow of urine out of the urinary drainage bag. The drainage bag system further includes a receptacle bag of a foil or sheet material for emptying the urinary drainage bag and having a receptacle compartment for storing urine and a connector for providing a connection between the receptacle bag and the urinary drainage bag. The connector provides a second inlet constituting a receptacle inlet to the receptacle compartment when connected to the receptacle bag such that urine can flow into the receptacle compartment.

A lubricating oil composition includes a major amount of an oil of lubricating viscosity and about 0.1 wt. % to about 10 wt. % actives, based on the total weight of the lubricating oil composition, of at least one Mannich reaction product prepared by the condensation of a polyisobutyl-substituted hydroxyaromatic compound, wherein the polyisobutyl group is derived from polyisobutene containing at least about 70 wt. % methylvinylidene isomer and has a number average molecular weight of from about 400 to about 2500, an aldehyde, an amino acid or ester derivative thereof, and an alkali metal base. The lubricating oil composition can have a TBN of 5 to 200 mg KOH/g. The 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.

Polyisobutylenes (PIBs) containing a high proportion of vinylidene end groups are generally favored over conventional PIBs because of their higher reactivity in reactions that are needed to prepare fuel and lubricant additives. However, detergent additives that have been prepared from conventional PIBs actually perform better than detergent additives prepared from high reactive PIBs. Specifically, detergent additives that were prepared from conventional PIB that was then enriched with tri- and tetra-PIB resulted in altered thermal stability and improved detergency of the resulting compound as compared to the structures which were created using a high proportion of vinylidene end groups.
