    Most synthetic motor oils contain a blend of several different base oil chemistry. POA is good stuff but i wonder about the compatibility claims.

    I should never trust my memory. POA is not group 3 it is group IV.
    Which makes a big difference it is a true synthetic.

    Sorry to many what I was trying to say was there a local supplier and what are the positive and negative of this oil.

    I have not found a local supplier but they told me i can email them and order direct.
    As to the positives and negatives i am still working on that.

    They say it can be used safely with any current refrigerant. The thing that worries me about how they say that is they just say that it's safe they don't say that it's miscible.

    Here is their spiel.

    "SRO 500 Synthetic Refrigerant Oil is a fully synthetic industrial lubricant developed specifically for auto air conditioning compressors.

    It is especially formulated for severe service under conditions that are beyond the capabilities of conventional mineral oils. It is compatible with all commonly used refrigerants, and does not absorb moisture. Ideal replacement for Polyolester (POE) and Polyalkyleneglycol (PAG) lubricant, and superior to both.

    Features and benefits

    Improved wear protection

    Virtually non- hygroscopic

    Improved system efficiency

    Non toxic

    Ideal vacuum pump oil

    Prevents oil deposit formation in low temperature systems

    Reduces discharge valve deposits and improves compressor efficiency

    Very low pour point, zero wax content

    High viscosity index and high temperature stability

    Greater chemical stability in the presence of refrigerants

    Low volatility and low solubility for refrigerants such as R12 & ammonia.

    Compatible with all commonly used refrigerants

    Compatible with most refrigeration and air conditioning applications

    Miscible with all other refrigerant oils

    Does not affect commonly used O Rings, Gaskets or Seals

    Does not combine with moisture to cause internal corrosion in fluorocarbon systems

    Compatibility

    SRO 1000 and SRO 500 are the ideal lubricants for maximum efficiency in all applications.They can also be safely used in all systems, with all refrigerants including: R11, R12, R13b, HCFC-22, R123a, HFC-134a, R404A, R401a, R502, R22, R400+, R717 (ammonia), R600a (isobutane) and R290 (propane).

    Suitable for all applications

    SRO 500 Refrigerant Oil is suitable for reciprocating compressors with very
high operating temperatures, suitable for screw compressors, and for use with systems incorporating very low evaporator temperatures. It is compatible with other synthetic and mineral oils and is suitable to with all common refrigerants, including ammonia.

    SRO 500 is suitable for use in all motor vehicle air conditioning applications. Compatible with all commonly used lubricants and refrigerant types, also with all modern seal, gasket and hose materials; SRO 500 is the ideal oil for service applications. SRO 500 is non- hygroscopic giving you confidence that it will not carry moisture into systems where it can combine with fluorocarbon molecules to cause rapid corrosion. SRO 500 also prevents seal deterioration which is often a factor in R134a systems.

    Economical

    SRO 500 and SRO 1000 have a unique formula to minimise oil logging of heat exchangers, maximising heat rejection, improving system efficiency and reducing energy costs.

    Virtually Non-Hygroscopic

    Moisture reduces lubrication performance, and ice may form at low pressure points. Moisture also reacts with the refrigerant gas creating acid which attacks components, motor windings and generally shortens the life of the compressor. SRO 500 is virtually non-hygroscopic, which means parts will have longer life and need fewer oil changes.

    Non-Toxic

    Unlike other oils, SR0 500 is non-toxic. This makes the product easy to handle and either recycle or dispose of."

    I seem to remember a thread on here regarding alternatives to POE oil. And if memory serves, all were much susceptible to breaking down due to moisture. One or two of the alternatives would absorb the moisture, but not be affected by that moisture.

    And the reason those oils were not commonly used was solely due to price. So, what does this oil cost per gallon, after the shipping costs.
    I do a triple evac with nitro to remove non condensables.

    It would probably cost more than the vehicle I drive just to ship it from Australia from what I've heard about about International shipping.

    I figured that's what you meant.
