The disclosed technology provides lubricating composition comprising: an oil of lubricating viscosity, a p-dodecyl-phenol-free detergent and an oxyalkylated hydrocarbyl phenol, wherein the oxyalkylated hydrocarbyl phenol is substituted with at least one aliphatic hydrocarbyl group of 1 to 250 carbon atoms (or 20 to 220, or 30 to 150 carbon atoms), and wherein the oxyalkylated hydrocarbyl phenol is substantially free of aromatic hydrocarbyl groups. The disclosed technology further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The disclosed technology further relates to the use of the of the lubricating composition in a passenger car internal combustion engine to improve control of at least one of the following (i) fuel economy, (ii) corrosion, (iii) cleanliness, and (iv) bore wear.

A lubricant includes at least 45 wt % paraffin oil, less than 8 wt % of a pyrophosphate or triphosphate, more than 6 wt % of a group 6 disulfide or diselenide and up to 27.5 wt % of graphite. The lubricant is used in a method for producing a magnesium alloy tube via extrusion, and is especially useful to form implants such as stents while maintaining the biocompatibility of the magnesium alloy.

The invention is a fluid having a kinematic viscosity from 3 to 6 mm.sup.2/s, a flash point of higher than 120° C. and a pour point lower than −40° C., having a boiling point in the range of from 200° C. to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% isoparaffins and less than 3% of naphthens by weight, a biocarbon content of at least 95% by weight, containing less than 100 ppm aromatics by weight. The invention is also a drilling fluid and the use of the fluid to improve the viscosity of the drilling fluid.
