A lubricating oil including a lubricating oil base stock as a major component; and a mixture of (i) one or more protected lubricating oil additives having a first performance function, and (ii) one or more unprotected lubricating oil additives having a second performance function, as a minor component. The first performance function and the second performance function are the same. The one or more protected lubricating oil additives are inactive with respect to their performance function. The one or more protected lubricating oil additives are converted into one or more unprotected lubricating oil additives in the lubricating oil in-service in an engine or other mechanical component. A method for controlled release of one or more lubricating oil additives into a lubricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives.

Compositions including one or more lubricating oil additives having at least one protected active group. A method for improving solubility of one or more lubricating oil additives in a lubricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives. A method for improving friction control in an engine or other mechanical component lubricated with a lubricating oil.

Methods, systems, and apparatus, including computer program products and implementing techniques for mixing liquid components. Quantities of two or more liquid components are transferred from pressurized source reservoirs to one or more destination locations by means of a fluid outlet that includes a dispense valve, and the two or more liquid components are mixed in the destination locations to create a plurality of fluid mixtures. Two or more dispensing technologies can be combined to provide for increased efficiency in the dispensing of high volume liquid components. The amounts of liquid components being dispensed can be monitored during the dispensing to provide feedback control of the dispensing.

A method and system to blend components to form a lubricant having a predetermined characteristic. The method includes determining the characteristic from a model that relates that characteristic as a function of the amount of its components and properties of the components. These predetermined characteristics include KV (kinematic viscosities), CCS (cold cranking simulator), HTHS (high temperature, high shear viscosity), Noack Volatility, MRV (mini-rotary viscometer), Brookfield Viscosity, Soot-Dispersancy, Oxidation, Deposit, Wear, Sulfur, Phosphorus, Base Number, Color, Ash Content, Aniline Point, Acid Number, Viscosity Index, Turbidity, Demulsibility, Foam Stability, Acute Toxicity, Biodegradability, Nitrogen, and Detergency.

Automated intelligent system for lubricant manufacture optimization

The present invention relates to a method of dispensing accurately small amounts of high viscosity lubricant components using tubeless positive-displacement liquid-handling equipment for forming lubricant blends. The method includes the steps of: providing a low void volume positive displacement pipette with a tapered tip for each lubricant component contained within a lubricant additive reservoir, and one or more lubricant blend containers; ingesting into a low void volume positive displacement pipette from a lubricant additive reservoir an ingestion volume of a lubricant component; moving the low void volume positive displacement pipette from the lubricant additive reservoir to the one or more lubricant blend containers; ejecting into the one or more lubricant blend containers an ejection volume of the lubricant component from the low void volume positive displacement pipette; returning the low void volume positive displacement pipette from the one or more lubricant blend containers to the additive reservoir; and repeating these steps for each additional lubricant component. The advantages of the method of the present invention include improved dispensing accuracy, quicker dispensing, lower shear rate during dispensing, lower temperature for dispensing, less residual additive on the tip of the device after dispensing, and the ability to real time monitor density and mass during dispensing. The method finds application in laboratory test environments, and in particular in high throughput testing environments.
