A lubricant additive for introduction into an AC/R system to improve lubricant miscibility and performance in the AC/R system.

A refrigeration apparatus includes a compressor, a first heat exchanger, an expansion mechanism, and a second heat exchanger. The compressor compresses low-pressure gas refrigerant and discharges high-pressure gas refrigerant. The first heat exchanger condenses high-pressure gas refrigerant and discharges high-pressure liquid refrigerant during an air-cooling operation, or evaporates low-pressure gas-liquid mixed refrigerant and discharges low-pressure gas refrigerant during an air-heating operation. The expansion mechanism has metal components. High-pressure liquid refrigerant passes through the expansion mechanism, and becomes low-pressure gas-liquid mixed refrigerant. The second heat exchanger evaporates low-pressure gas-liquid mixed refrigerant and discharges low-pressure gas refrigerant during an air-cooling operation, or condenses high-pressure gas refrigerant and discharges high-pressure liquid refrigerant during an air-heating operation. The refrigerant contains at least 60 wt % of R32. An acid scavenger added in an amount of 1.0 wt % to 5.0 wt % is blended in refrigerator oil for lubricating the compressor.

Disclosed herein is a fuel composition having (1) greater than 50 wt % of a hydrocarbon fuel boiling in the gasoline or diesel range and (2) a minor amount of a low-speed pre-ignition (LSPI)-reducing additive having one or more of an amidine, or a beta-amino alkanol having the structure
