Can I Mix Pag 46 With Pag 150

No, you should not mix pag 46 with pag 150 lubricants. Mixing different viscosity grades of pag oils can compromise the performance and durability of your refrigeration system.

When it comes to refrigeration systems, using the right lubricant is crucial to ensure the smooth operation of its components. While pag oils are highly effective in absorbing moisture and reducing wear and tear, it is important to choose the correct viscosity grade for your system’s needs.

Mixing different grades can cause the lubricant to break down, which can lead to reduced efficiency, increased energy consumption, and higher maintenance costs. Therefore, it is always best to consult with a qualified technician and follow the manufacturer’s recommendations before adding any type of oil to your refrigeration system.

Understanding Pag 46 And Pag 150

When mixing different pag oils, you need to understand their chemical properties. Pag 46 has a lower viscosity and is recommended for most automotive applications. It absorbs moisture quickly and is not compatible with mineral oils. Pag 150, on the other hand, has a higher viscosity and is suitable for commercial and industrial refrigeration systems.

It is also hydrophilic, which means it can absorb large amounts of moisture. Mixing these two types of oils may compromise the chemical properties of the final blend, leading to performance issues. Therefore, it’s essential to consult the manufacturer’s recommendations before mixing pag 46 with pag 150.

Factors To Consider Before Mixing Pag 46 And Pag 150

Mixing different lubricants can be troublesome, and it’s vital to consider several factors before combining pag 46 and pag 150. Firstly, assess your system compatibility since the mix could interfere with your machine’s functionality. Secondly, check out the lubricant properties to ensure the new blend meets your requirements.

Lastly, follow oem recommendations to avoid voiding the warranty or causing damage to the application. Ignoring these factors can result in premature equipment failure, leaks, or reduced efficiency. Therefore, it’s crucial to conduct research, consult with experts to ensure the right blend, and avoid any potential complications during operation.

Always prioritize system longevity, performance, and safety over convenience to avoid costly mistakes.

Consequences Of Mixing Pag 46 And Pag 150

Mixing pag 46 and pag 150 in your air conditioning compressor may seem like an easy fix, but the consequences could be severe. You risk reduced lubrication, leading to increased wear and tear. Compressor damage is also likely, ultimately resulting in system failure.

It’s important to stick to the manufacturer’s recommendations regarding lubricant viscosity and type. Mixing different types of lubricants can cause chemical reactions that may damage the compressor. The integrity of your entire air conditioning system is at stake, so it’s best to avoid mixing different lubricants and instead follow the specified guidelines.

Spare yourself the troubles of unnecessary repairs by taking preventive measures and regular maintenance advised by your manufacturer.

Alternatives To Mixing Pag 46 And Pag 150

Mixing pag 46 and pag 150 may not be the best idea. However, there are some alternatives to consider. You could try flushing the system before adding fresh oil, or simply replace the oil completely. Another option is to use an oil additive, which can help improve performance and protect your system.

If all else fails, seek professional help from a mechanic or technician who can offer knowledgeable advice. By following these suggestions, you can ensure that your system stays healthy and runs smoothly for years to come.

Frequently Asked Questions On Can I Mix Pag 46 With Pag 150

Is It Safe To Mix Different Viscosity Pag Oils?

what is the ideal ratio for mixing pag 46 and pag 150?

Answer 1:

It’s generally not recommended to mix refrigerant oils with different viscosities.

Answer 2:

Mixing pag 46 and pag 150 oils can compromise the a/c system’s performance.

Answer 3:

Mixing different viscosity pag oils can cause compressor failure and clog filters.


After carefully evaluating the compatibility of pag 46 and pag 150, it appears that mixing these two lubricants is not recommended. Although the chemical composition of these pag oil types share similarities, their performance characteristics and viscosity levels vary significantly.

Mixing them would result in an unstable lubricant that could potentially damage your ac system and cause compressor failure. It is crucial that you follow the manufacturer’s recommendations and guidelines when selecting and replacing pag lubricants. Always remember that using the wrong type or mixing incompatible lubricants can result in costly repairs and downtime.

Therefore, it’s recommended that you stick to using a single lubricant type and avoid mixing pag 46 and pag 150. We hope this article has been informative in educating you about the compatibility and mixing of pag 46 and pag 150.
