PAO Vs MPAO for Lubricant Formulation: Selection Guide for Modern Synthetic Lubricants

PAO and mPAO are both widely used in synthetic lubricant formulations. The optimal choice depends on volatility targets, viscosity requirements, oxidation stability goals, and operating temperature conditions.

When Is PAO Typically Used?

PAO is commonly selected for:

• Industrial gear oils

• Compressor oils

• Hydraulic fluids

• Automotive lubricants

It offers a well-established balance of performance and formulation flexibility.

When Is mPAO Typically Used?

mPAO is often considered when formulations require:

• Higher viscosity index

• Lower volatility

• Improved efficiency

• Enhanced low-temperature performance

Which Applications Benefit Most from mPAO?

EV Transmission Fluids

Require efficiency and temperature stability.

High-Performance Gear Oils

Require durability and oxidation resistance.

Long-Life Industrial Lubricants

Require extended service intervals.

Can PAO and mPAO Be Combined?

Yes.

Many formulations use a blend of PAO and mPAO to achieve target performance characteristics.

FAQ

Is mPAO Always Better Than PAO?

No. Performance requirements determine the appropriate choice.

Can PAO and mPAO Be Mixed?

Yes, blending is common.

Which Base Oil Has Lower Volatility?

mPAO generally provides lower volatility.
