“Toyota and our supplier ExxonMobil may experience challenges in fulfilling demand for Genuine Toyota Motor Oil (GTMO) 0W-8 and 0W-16 oils due to production and logistics constraints within the global petrochemical supply chain. While Toyota and ExxonMobil continue to work diligently to maintain supply, the following substitution guidelines are recommended for dealers to help manage the demand for the affected products. These measures may allow ExxonMobil to maintain a consistent service-level fill for dealers and help provide continued support for our guests.”

While Toyota and ExxonMobil continue to work diligently to maintain supply, the following substitution guidelines are recommended for dealers to help manage the demand for the affected products. These measures may allow ExxonMobil to maintain a consistent service-level fill for dealers and help provide continued support for our guests.”

To alleviate supply woes, the bulletin also instructed dealers to field substitutes in light of storage, albeit only for one service interval. According to the bulletin, 20% of incoming cars that require 0W-8 GTMO will use 0W-16 GTMO instead, and 10% of incoming cars that require 0W-16 will use 0W-20 GTMO. The bulletin further clarifies:

  • “Toyota Genuine 0W-8 motor oil can be substituted with Toyota Genuine 0W-16 for one service interval.”
  • “Toyota Genuine 0W-16 motor oil can be substituted with Toyota Genuine 0W-20 for one service interval.”
  • “Always use Toyota Genuine API SP (0W-16) / GLV-1 (0W-8) multigrade oil of the specified viscosity.

I use 5w30, so I guess it's irrelevant...
