Irving discovered that a portion of its premium grade of gasoline was not meeting octane specifications at select service stations, principally within New Brunswick, as the gasoline had been mixed accidentally with lower-octane gasoline.
The malfunction appears to have let some regular gasoline mix with the Supreme grade, making the Supreme and mid-grade blends of gasoline off-specification at some fuel stations, according to the company.
Initial testing indicates specifications for the fuel were below the required level (91 octane), but generally higher than mid-grade gasoline (89 octane).
The company is presently confirming which sites received the affected product and is working to deliver on-specification Supreme fuel to all affected stations within the week.
Irving Oil has also ordered an independent audit of its process and quality control systems, in addition to voluntarily disclosing the discovery of its off-specification Supreme fuel to government regulators and customers.
