It meets the SAE viscosity class of 110 cSt at typical test conditions and is marketed as a universal-fit product for equipment that specifies mineral oil for R12. Use only where a compatible mineral oil is recommended by the equipment manufacturer.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this oil fit into R12 A\/C service work?\u003c\/h3\u003e\n\u003cp\u003eTSI Supercool MO-500-GM-32 replaces or replenishes the mineral oil in A\/C systems built for R12 refrigerant. It helps maintain lubrication of bearings, pistons and valves in compressors that require mineral-oil formulations rather than polyalkylene glycol (PAG) or POE oils used with newer refrigerants.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with compressors and components specified for mineral oil and R12.\u003c\/li\u003e\n  \u003cli\u003eSold in a 32 oz bottle for top-ups or partial oil changes.\u003c\/li\u003e\n  \u003cli\u003eViscosity rating of 525 VIS (SAE 110 cSt) for high-load lubrication.\u003c\/li\u003e\n  \u003cli\u003eUniversal-fit label indicates broad OEM compatibility where mineral oil is specified.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat do the viscosity numbers mean for performance?\u003c\/h3\u003e\n\u003cp\u003eThe 525 VIS and SAE 110 cSt values indicate a relatively thick oil at a reference temperature, delivering a robust lubricating film under compression and hot operating conditions. Higher cSt numbers generally mean a thicker lubricant, which can be beneficial for older or high-load compressors; check manufacturer guidance to match viscosity to your system.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e525 VIS denotes the measured viscosity used by the brand to describe flow characteristics.\u003c\/li\u003e\n  \u003cli\u003eSAE 110 cSt identifies the oil’s class for comparing with other compressor oils.\u003c\/li\u003e\n  \u003cli\u003eHigher viscosity helps maintain film strength at elevated temperatures and pressures.\u003c\/li\u003e\n  \u003cli\u003eNot interchangeable with PAG or POE oils unless the system specifies mineral oil.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I use and store this 32 oz bottle safely?\u003c\/h3\u003e\n\u003cp\u003eFor service, add oil to the system only as directed by the vehicle or equipment service manual; topping off is common, but full compressor oil change procedures may require evacuation and oil measurement.

Choose TSI Supercool MO-500-GM-32 when the equipment documentation calls for mineral oil of approximately SAE 110 cSt viscosity and you need a 32 oz quantity for topping up or partial oil service.
