**Compressor Oil - What Color Should It Be?**

Have you ever wondered, “What color should my compressor oil be?†The answer is simple: when new, it should be a light yellow or amber in color. While this might seem like a basic question, monitoring the color of your compressor oil is essential for maintaining the performance and longevity of your equipment.
We recently sent a customer a batch of PAG 46 compressor oil, which is a popular replacement for brands like Ultra Coolant. The oil arrived with a clear, yellowish tint—exactly what you’d expect from a fresh product. However, the customer was confused because the oil in their compressor looked completely black. This raised some red flags.
Upon further discussion, we learned that the customer had recently had a service technician change their oil. The technician used old, heavily contaminated oil and claimed it was “new.†When we saw the photo they provided, it was clear that the oil was not only dark but also extremely dirty.
This situation highlights a critical point: always check the condition of your compressor oil before and after maintenance. If the oil has turned very dark, smells burnt, or appears cloudy, it may be time for a change. Milky or cloudy oil can indicate water or coolant contamination, which can lead to serious damage if left unchecked.
To avoid such issues, it's wise to perform regular maintenance checks and consider using high-quality, reliable compressor oils. Our Made in USA compressor oil offers excellent performance at a great value, helping you save money while ensuring your system runs smoothly.
Remember, never let a service technician reuse your old oil. Always use fresh, clean lubricant to protect your compressor and extend its lifespan.
