A composition is provided for a non-aqueous foaming aerosol cleaner or lubricant. Foam builders, especially silicone glycol copolymers, are used to generate high density foam of the solvent-based formula. A cleaning product variant may be introduced via an air intake route for loosening deposits in an internal combustion engine. The high foam aerosol product dispenses easily without causing engine stalling. A process of lubricating a target substrate is also provided.

The instant disclosure provides a process for preparing a lubricant or fuel additive mixture where an oil of lubricating viscosity or fuel are blended with additives that are mixed via an acoustic mixer. The additives and oil of lubricating viscosity or fuel can mixed together or any component of the lubricant or fuel additive mixture can be mixed separately prior to mixing to form the final lubricant. The process provides for continuous mixing to form lubricant and/or fuel additive mixture final products.

The present invention relates to a nitrogen-containing diesel solidification point depressant composition, and preparation and application thereof. The nitrogen-containing diesel solidification point depressant composition includes the following components in percentage by weight: 10-40% of monoisopropanolamine; 10-40% of cyclohexane; 0-20% of polyethylene glycol; and 40-60% of N-tetradecyl methacrylamide-tetradecyl methacrylate. After the prepared diesel solidification point depressant composition is added to commercially available 0 #diesel, a solidification point and a cold filter plugging point of the diesel are respectively depressed by 21-25° C. and 9-13° C.
