Provided herein are friction reducers comprising a thickening agent, a liquid medium, and a stabilizing agent; and methods and uses thereof for the treatment of an oil and/or gas well having a wellbore.

A system is provided for creating a high lubricity substance from a fuel while said fuel is being used to operate a mechanical device such as an engine, thereby increasing the lubricity the fuel and allowing the fuel to be used as a lubricant for various tribological surfaces inside the engine without the use of further additives or modifiers. In this regard, an embodiment of the present disclosure may include a device that has a first surface upon which is deposited a film. The first surface of the device and the associated film may be in continual contact with a fuel. The device may comprise a second surface that is brought into periodic and/or repeated contact with the first surface, such as through sliding contact, rolling contact, a combination of the two, and/or the like.

A lubricating oil composition and method of operating a boosted internal combustion engine. The lubricating oil composition includes a major amount of a base oil, one or more overbased calcium-containing detergents having a total base number of greater than 225 mg KOH/gram, to provide greater than 900 ppm by weight to less than 2400 ppm by weight of calcium to the lubricating oil composition, and a low speed pre-ignition reducing amount of one or more titanium-containing compounds to provide from 10 ppm to 3000 ppm titanium and/or one or more tungsten-containing compounds to provide from 125 ppm to 3000 ppm tungsten, all based on the total weight of the lubricating composition. The low speed pre-ignition events in the boosted internal combustion engine may be reduced relative to a number of low speed pre-ignition events in the same engine lubricated with the same lubricating oil without the titanium- and/or tungsten-containing additive.
