Buying advice

Choose A/C oil based on your vehicle's compressor type and refrigerant (PAG for R-134a, ester for retrofits). Check your manual for viscosity (e.g., PAG 46, 100, 150). For older R-12 systems, use ester oil. UV dye oils are helpful for leak detection. Stick with reputable brands for reliable performance.
