A lubricating oil composition comprising a heavy high saturates base oil is provided. Methods for using said lubricant composition for lubricating an engine, a gear box, and in general industrial lubricant applications, including as a bearing and circulating oil, are also provided.

The lubricating oil composition for four-stroke cycle engine of the present invention includes a base oil (A) and from 0.5 to 10% by mass of a polyolefin (B) having at least an isobutene-derived constituting unit and having a number average molecular weight of 500 to 10,000, with a sulfated ash content being from 0.3 to 1.2% by mass.

The present disclosure relates to a lubricant for marine engines including at least one base oil, at least one overbased detergent, at least one neutral detergent and at least one fatty amine.

Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510 C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.

Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510 C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks. The catalytic processing can correspond to processing in at least two stages. The amount of conversion performed in each stage can be varied to produce bright stocks with various properties.

Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.

Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.

A lubrication product used in the packings and plungers of hydraulic pumps used in fracking and other oilfield applications. The composition including: 1) diluent oil, comprising of naphthenic, paraffinic, or synthetic origin ranging from 60 SUS to 3000 SUS at 100 F.; 2) olefin co-polymers, either high propylene or high ethylene, or combinations thereof; 3) polybutene, ranging in molecular weights from 100-6000 4) high molecular weight poly-ISO-Butylene, ranging from 500,000 to 3,000,000; 5) PIBSA dispersant; 6) performance additives, containing anti-wear and extreme pressure properties. Most preferable is a sulfur/phosphorus gear oil package.

A base oil for a refrigerating machine oil, having cyclic saturates of 40% by mass or less and non-cyclic saturates of 60% by mass or more in saturates, a density at 15 C. of 0.805 g/cm.sup.3 or lower, and a normal paraffin content of 50% by mass or less.
