As the summer driving season approaches, rising gas prices might not be the only hurdle confronting travelers. We are also facing a possible shortage of specific motor oils. Although there’s no immediate indication of a threat to retail motor oil supply, current-generation Toyota hybrid owners (numbering in the millions) should be aware that their upcoming oil change could be unusual.
Toyota reportedly issued a notice to its service centers late last month indicating an upcoming scarcity of certain oil grades. The communication notes that ExxonMobil anticipates ongoing deficiencies of 0W-8 and 0W-16 due to the current state of the petrochemical market and advises dealers to utilize heavier oils to address any supply gaps.
Toyota refers to these communications as “PANT” (Parts & Accessories News Today) bulletins, and Costa Kapothanasis (@CostaKapo on X), who owns a significant chain of oil change services, shared the first page of the April 30 edition, which succinctly outlines the situation.
From other PANT Bulletin examples we have found online, the memo appears to be authentic. We contacted a Toyota representative for confirmation of its legitimacy and the accuracy of its recommendations. As of the time of publication, Toyota had not responded to our inquiries regarding either matter.
In case the link fails or the image is too complex to decipher, here’s the pertinent section in its entirety:
Toyota and our supplier ExxonMobil may face obstacles in meeting demand for Genuine Toyota Motor Oil (GTMO) 0W-8 and 0W-16 oils due to production and logistics issues within the worldwide petrochemical supply chain. While Toyota and ExxonMobil are actively striving to maintain supply, we recommend the following substitution guidelines for dealers to assist in managing demand for the affected products. These steps may enable ExxonMobil to uphold a consistent service-level fill for dealers and continue supporting our customers.
TMNA suggests that dealers adhere to these substitution guidelines one day weekly for 0W-8 and one day biweekly for 0W-16 or apply the substitution percentages provided below until further written communication is received. This strategy aims to temporarily diminish demand for both oil grades and assist in sustaining national supply.
The memo also detailed substitution guidelines and specified that they should not be relied upon indefinitely; each is permitted for just one service interval, it stated.
But is this suitable for your vehicle? In short, yes.
Toyota already has measures in place for substitutions if a specific motor oil grade is unavailable. This memo is designed to aid service departments in managing their stock during the shortage.
Generally speaking, a heavier weight oil increases drag between components, which diminishes efficiency and transforms more of the engine’s output into excessive heat. Lighter-weight oils achieve the opposite effect but may not sufficiently lubricate an engine if its tolerances are too loose.
Neither scenario is ideal, but in certain cases, a varying oil weight can still fall within a manufacturer’s specifications for basic engine protection but fail for other reasons, such as fuel efficiency (too heavy) or oil consumption (too light). Every engine has its “just right” range, but “adequate” will suffice in an emergency.
And clearly, service centers are beginning to feel the strain. If you’re due for an oil change, it may be wise to take care of it sooner rather than later. If ground reports are accurate, this isn’t merely an issue for dealers. Certain weights are already in short supply at the retail level. Kapothanasis mentions that the situation is only expected to worsen:
