Platts invites feedback on US gasoline RVP calendar for 2026

As part of its commitment to open and transparent pricing and product specifications, Platts, part of S&P Global Energy, would like to invite feedback regarding publishing dates and/or cycles for 2026 US gasoline RVP shifts.

The 2026 calendar largely follows 2025 norms, with no notable deviations from prior years. The calendar will be updated throughout the year as more information becomes available.

The shift dates are based on relevant pipeline schedules, historical information, and feedback from market participants.

US Gulf Coast shifts are based on the Colonial Pipeline schedule. US Atlantic Coast shifts are based on Buckeye Pipeline and Colonial Pipeline calendars.

On the West Coast, Los Angeles, San Francisco and Arizona RVP changes are based on Kinder Morgan's SFPP schedule, while Portland and Seattle shifts are based on Olympic Pipeline's calendar.

In the Midwest, Group 3 shifts are based on the ONEOK Pipeline schedule, while Chicago shifts are based on Explorer Pipeline and Buckeye Complex schedules.

The US Environmental Protection Agency removed a waiver in eight Midwestern states that allowed for an additional 1 psi during the summer. Platts will adjust the RVP Calendar for Chicago CBOB in accordance with the implementation of the waiver. More information can be found here.
