Think all lubricants are the same? From conventional to synthetic blends, you might think it makes little difference what you put inside your vehicle. But it’s time to think again. Oil formulas are constantly evolving to better technology to meet stringent emission requirements and increase engine efficiency. Recently, the new iteration of dexos® technology developed by General Motors (GM) has pushed the gasoline engine market into new territory. 

Dexos1™  Gen 1 

Five years ago, GM began developing an oil to take better care of engines than even a top-performing standard synthetic oil. Many modern full synthetics, with recommended change intervals of 5,000 and even 7,500 miles, already surpassed conventional oils, but GM saw an opportunity to raise the bar even further. 

The result was a new standard for the industry. Although initially developed exclusively for GM vehicles, dexos® oil became embraced by the entire market. The first generation of dexos® provided the following benefits: 

  • Mandated use of high-quality ingredients, which meant they eliminated conventional ingredients entirely. Dexos® oils are formulated exclusively with synthetics or synthetic blends. 
  • Better antioxidant technology that keeps oil from oxidizing. Dexos® oils generally have a drain interval of up to 15,000 miles. 
  • Lower viscosity that holds up to engine combustion and heat better and longer than other oils on the market. 

Dexos1™ Gen 2 Taking it to the next level 

Dexos1™ Gen 2 has all the benefits listed above, plus improved oxidation and deposit control. In addition, this new generation protects engines against a severely damaging phenomenon known as low speed pre-ignition (LSPI). LSPI affects smaller turbocharged engines that are prone to deposits and pre-ignition problems.  Although most vehicles are approved to use Gen 1, the new Gen 2 edition offers more advanced engine protection capabilities not found in Gen 1 oils. 

Wondering whether dexos® is right for your vehicle? Cenex offers Maxtron®, which is approved for dexos1™ Gen 2 standards in 0W-20 and 5W-30 formulations. Always consult your owner’s manual to ensure the product you choose is effective and safe to use with your vehicle.
