A recent internal news bulletin is advising Toyota dealers running low on 0W-8 Oil for RAV4, Highlander and Hybrid SUVs to mix with heavier oil when doing oil changes.
Toyota Dealers Running Low on 0W-8 Oil and 0W-16
The news bulletin issued on April 30, 2026 advises dealers that Toyota and their supplier ExxonMobil may experience a challenges in meeting demand.
This bulletin reads:
April 30, 2026
TO: Toyota Parts and Service Managers
SUBJECT: Temporary 0W-8 & 0W-16 Oil Supply & Maintenance Guidelines
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.
TMNA recommends dealers follow these substitution guidelines one day per week for 0W-8 and one day every other week for 0W-16 or use the substitution percentages set forth below until further written notice. This approach is intended to temporarily reduce demand for both oil weights and support continued national supply.
Substitution Percentages:
• Reduce current 0W-8 demand by 20% by filling 20% of 0W-8 oil changes with 0W-16 GTMO.
• Reduce current 0W-16 demand by 10% by filling 10% of 0W-16 oil changes with 0W-20 GTMO.
Substitution Guidelines:
• Toyota Genuine 0W-8 motor oil can be substituted with Toyota Genuine 0W-16 for one service interval.
