Is There A Dye To Color Or Darken Clear Hydraulic Or Compressor Oils?

A reader asks: We have a variety of compressor and hydraulic systems in our plant. Our technicians frequently complain about difficulty with seeing clear oils in sight glasses. We’ve even had situations where production has been temporarily halted because we mistakenly believed that a reservoir was below the safe level. Do you offer a coloring that darkens the oil? It would help us with “hard to see” oil levels on sight glasses.

Our Answer: There is a product for coloring oils that is readily available. Heavy-equipment maker Caterpillar offers oil-soluble dyes that are suitable for most compressor, hydraulic, R & O and transmission fluids.

We have spoken to people that have had very good results with this product in hydraulic oil reservoirs. It immediately makes clear oils much more visible in sight glasses and on dipsticks.

These dyes are available from most CAT heavy-equipment dealers. CAT dealers are located all over the world. Please note that we do not sell CAT brand oil dye and have no affiliation with Caterpillar Inc.

Applications And Mixing Directions For CAT Oil Dye

Caterpillar Oil Dyes are available in the colors blue or red. They are soluble with most industrial hydraulic, compressor or gear oils where increased visibility is desired. It is best to consult your CAT dealer to ensure that the dye product is compatible with your intended application.

The recommended mix ratio is 16000:1. This means that 1 US ounce of dye will treat 125 US gallons of oil. The metric ratio is 6 milliliters of color to 100 liters of oil.

The Cat dye container size is 8 US ounces (240 ml). The entire container can treat 1000 US gallons (3785 liters) at the recommended mix rate.

Cat Oil Dye Part Numbers

Blue dye- New part number: 486-1536 (Old part number: 9U-5032)
Red dye- New part number: 486-1535 (Old part number: 9U-5031)

A Warning About Using Oil Dyes

Oil dyes are generally very concentrated. It is vital to wear gloves when handling oil dyes. Any contact with skin could lead to long-term staining.

In conclusion, oil dyes are an easy, safe and commonly found solution for clear industrial fluids.

An Equivalent For Mobil Rarus 427 Compressor Oil

AMSOIL PC Series Synthetic Compressor Oils

AMSOIL PC ISO 100 is an ideal replacement for Mobil Rarus 427 Compressor Oil

If you are looking for a synthetic alternative to Mobil Rarus 427 compressor oil, we’ve got an ideal substitute. The AMSOIL PC Series ISO 100/SAE 40 Synthetic Compressor Fluid is a cost-effective upgrade for the Mobil offering at a surprisingly reasonable price.

We can sell this quality Mobil Rarus 427 replacement at wholesale prices in the United States and Canada. Request a price list using the form on this page or call us at 1-800-748-5781. 

AMSOIL PC Series VS. Mobil Rarus 427

The AMSOIL Compressor Fluid is a 100% synthetic fluid, while the Rarus 427 oil is a mineral-based oil. The synthetic composition of the AMSOIL product brings a host of advantages over Rarus 427.

Long Service Life

AMSOIL PC Series boasts a long service life of up to 8000 hours, due to its robust synthetic composition and top-quality additive package. Mobil claims the Rarus 427 fluid is capable of a “long service life”, but offers no specifics as its actual lifespan.

Lower Friction

Synthetic oil offers inherently lower friction over any conventional, mineral-based fluid. AMSOIL PC Series ISO 100 can optimize compressor operation and play a role in the reduction of energy costs.

Cleaner Operation

Synthetic oils have high detergency properties over conventional oils also and tend to have considerably better resistance to high temperatures. High temperatures can lead to increased deposit production with mineral-based oils. This all adds up to AMSOIL PC series offering the cleanest, most deposit-free possible operation.

Massive Cold Temperature Advantages

Mobil Rarus 427 has a cold-pour-point of -9°C (16°F), whereas AMSOIL PC ISO 100 flows down to -44°C (-47°F). For applications that are subject to cold temperatures such as mobile compressors, the AMSOIL advantage is a game changer. This huge edge is typical of the superiority of synthetic oil over mineral-based products.

Value Price

In many markets, AMSOIL PC Series ISO 100/SAE 40 Synthetic Compressor Fluid is priced similarly to Mobil Rarus 427. Considering the operational advantages of synthetic compressor oil, AMSOIL PC ISO 100 is an outstanding value. We can offer this product at wholesale prices for your company.
