The present disclosure describes lubricant compositions effective to reduce lead corrosion through an admixture of lubricant additives including at least a base oil of lubricating viscosity, a dispersant, a friction modifier, and boron-containing compound.

The instant disclosure generally relates to lubricating compositions having an oil of lubricating viscosity, a mixture of boron-containing and boron-free dispersants, an overbased magnesium-based detergent, an overbased calcium-based detergent, an ashless friction modifier, and, optionally, other performance additives. The instant lubricating compositions may improve one or more of cleanliness, TBN retention, fuel economy and low-speed preignition (“LSPI”).

The invention relates to the use of at least one triazole compound as an additive for improving the anti-corrosion properties of a lubricant composition for a propulsion system of an electric or hybrid vehicle, said lubricant composition comprising one or more amino and/or sulfur anti-wear additives. The invention also relates to the use of a lubricant composition for lubricating a propulsion system of an electric or hybrid vehicle.

The present invention relates to a hydraulic fluid composition containing a base oil (A), an antioxidant (B) including an amine-based antioxidant (B1) and a phenol-based antioxidant (B2), and a succinimide-based compound (C), wherein the hydraulic fluid composition satisfies the following requirement (I); and is to be used for hydraulic equipment which is equipped with at least one of a wet type brake and a wet type clutch and which is selected from a construction machinery, a general industrial machinery, and a power generator, and in which a working pressure is 30 MPa or more. The hydraulic fluid composition is not only excellent in wear resistance and an effect for suppressing the sludge formation but also excellent in a braking performance or a clutch performance, even when used under a high-pressure condition. Requirement (I): A static friction coefficient (μ.sub.s) after 1,000 cycles, as measured in conformity with the SAE No. 2 test described in JCMAS P 047:2004, is 0.100 to 0.162.

With the present invention, sustainable systems for corrosion, inhibition in the processing of metals (in particular iron, aluminum and magnesium) are made available. These systems being in full accordance with the principles of green chemistry comprise an amino acid as neutralizing component for an acidic corrosion inhibitor, whereby the amino acid is used in deprotonated form. The resulting metalworking fluids may be water- or oil-based or semi synthetic formulations. The neutralization of acidic corrosion inhibitors with the claimed system comprising an amino acid consistently achieves convincing results and, together with acidic corrosion inhibitors from corresponding sources, completely renewable systems for corrosion inhibition are provided.
