Synthetic basestocks for automotive engine oils

The highest performance standards for passenger car and heavy-duty engine oils can be met using synthetic basestocks such as:

  • SpectraSyn™ PAO  
  • SpectraSyn Plus™ Advanced PAO  
  • SpectraSyn Ultra™ High VI PAO  
  • Synesstic™ AN (Alkylated Naphthalene) Blendstocks
  • Esterex™ esters

These chemically derived synthetic basestocks offer numerous advantages over mineral oil basestocks, including:

  • Better oxidative and thermal stability for long service life  
  • Better volatility for reduced engine oil emissions  
  • No inherent contaminants to accelerate corrosion or acid formation  
  • Higher saturates level for greater soot-handling capabilities  
  • Lower pour points for improved operational low temperatures

Use:
SpectraSyn Lo Vis and SpectraSyn Hi Vis PAO to formulate high-quality engine oils. 

SpectraSyn Plus Advanced PAO to formulate top-tier engine oils as well as other high-performing automotive, aviation and military applications requiring improved volatility and low-temperature performance.

SpectraSyn Ultra High VI PAO to enhance engine oil performance through additional wear protection and VI improvement.

Synesstic AN in engine oil applications that require high stability under extreme operating conditions.

Esterex esters for fully synthetic passenger car engine oils and heavy-duty engine oils.
