Does Phillips 66 produce an All Weather or High Viscosity Index hydraulic fluid?

Yes, Phillips 66 uses the HVI or HE acronym to denote multi-viscosity fluids. HVI stands for High Viscosity Index and HE stands for High Efficiency.

Yes, Phillips 66 offers four hydraulic fluids that have different levels of biodegradability. Inherently or Readily.

  • Ecoterra (Inherently)
  • Ecoterra HVI (Inherently)
  • Ecoterra HVI-E (Inherently)
  • Syndustrial HF series (Readily)

Please note that moisture and dirt can affect the dielectric characteristics of the product. The dielectric strength values below are guaranteed at the point of manufacture.

  • Phillips X/C 5606 Aviation Hydraulic Fluids (49 kv)
  • Syndustrial Hydraulic Fluid (40 kv)
  • Arctic Low Pour (35 kv)
  • Ultra Powerflow HE (35 kv)
  • Powerflow HE (35 kv)
  • Ecoterra HVI (35 kv)

Syndustrial R&O is a Diester synthetic (Group 5). Syncon R&O is a Polyalphaolefin (PAO) (Group 4). PAO’s are the primary choice for typical compressor or pump applications. Diester’s are typically recommended in a compressor or pump application that is in severe service. Compressors that experience high valve temperatures may use a Diester because it leaves softer valve deposits which lessens the chance of a fire. Check manufacturer recommendation for equipment in severe service. If you have any questions please call 1300 744 554 for assistance.

As a general guide you can use the National Lubricating Grease Institute’s grease compatibility chart. When changing from one thickener to another please call the hotline for additional compatibility information. Some greases with the same thickener type may not be compatible. Technical services periodically runs compatibility studies against competitor’s products.

Powerflow is Phillips 66 premium product. It contains the highest levels of anti-wear additives and has the best resistance to oxidation. Megaflow is Phillips 66 main line product. It contains elevated levels of anti-wear additives and performs well resisting oxidation.

The ASTM D943 testing (oxidation) results are indicated on our TDS’s but only should be used as a laboratory baseline. Actual results are indicated when oils are put into service. Several factors determine the life of a product, most importantly Loads, operating temperature, and frequency of use. One piece of equipment versus another can give very different oil analysis results based on application.

Any application (i.e. Bucket Pins, Pivot Pins, etc) that is exposed to the atmosphere where you have metal on metal contact provides a big advantage. The reason, Moly is a solid additive (very hard) in grease and should the thickener get washed away the Moly is left behind to provide lubrication. Basically Moly gets compressed and squeezed within the bucket pin and provides a layer of lubrication. Moly in a bearing application is reserved typically for heavy duty equipment that experiences higher loads and where shock loads are present, although review equipment owner’s manual for recommendations.

A disadvantage of using Moly in a bearing application is that because since it is a very hard solid additive it can become abrasive in bearings specifically higher RPM applications where tolerances are tighter. Again, review equipment owner’s manual for specific recommendations.

Lubricant compatibility must be considered when topping off one product with another or if changing a product out to a different type of product for instance from Group IV to a Group V. Even some like products may not be compatible with each other. Our Industrial Product Coordinators periodically run compatibility studies with our products against competitor’s products. If we have not run a compatibility test we can certainly run one for a customer. As I previously mentioned some Group V products are not compatible with Group IV PAO’s (Polyalphaolefin). For instance, some PAG’s (Polyalkylene Glycol) are not compatible with PAO’s or other mineral based products. For assistance with compatibility questions please call our Technical Hotline at 1300 744 554.

Another consideration is seal compatibility. Some oil products are not compatible with certain seal materials. The manufacturer can advise you what seal materials are being used in the piece of equipment. If you have questions about seal compatibility please call the Technical Hotline at 1300 744 554.
