Abstract (en)
[origin: WO2011130142A1] The lubricant for a sump-lubricated, compression-ignited engine may contain an amount of a C12-C24 carboxylic acid-based fuel additive or component obtained by migration from the fuel. Good lubricant performance is obtained by including in the lubricant a boron-containing additive in an amount to provide about 2 to about 500 ppm B to the lubricant, provided that the total sulfated ash level is less than 0.8 weight percent.
