Source: EIA Form 888 on-highway diesel weekly survey (the "DOE National Average").
The TOE Retail Pressure Index (RPI-C) turns weekly EIA retail fuel prices into a single 0–100 reading of how much upward (or downward) pressure a fuel is under — relative to its own recent history, not its absolute price. It blends four independent signals so that no single quirk (a seasonal pattern, a one-week spike, an isolated regional move) dominates the picture.
Data sources
- EIA Form 878 — Motor Gasoline
- Weekly retail regular gasoline survey (~900 outlets). National, regional (PADD) and California series.
- EIA Form 888 — On-Highway Diesel
- Weekly retail on-highway diesel (ULSD) survey (~590 outlets). National, PADD and California series.
- Release cadence
- Both surveys publish Mondays after 5:00 PM ET (the prior Monday's pricing). A federal-holiday Monday delays the release a day.
- PADD regions
- The five Petroleum Administration for Defense Districts (PADD 1 East Coast … PADD 5 West Coast) are the geographic backbone for the Breadth Index and the state heat map.
- What it is not
- These are survey aggregates, not station-level transaction prices. The Pressure Index measures relative pressure, not absolute cost — so a low-price region can still read high pressure.
The RPI-C index family
Four component indices feed the composite. Each is computed per fuel from the stored weekly observations; each is shown on the Pressure tab alongside the headline.
Where today's price sits within its own 5-year trailing range.
100 · (p − min) / (max − min)
e.g. If the 5-yr window runs $2.00–$6.00 and today is $4.00, RPI = 100·(4−2)/(6−2) = 50.
How unusual the price is for this specific week of the year, vs the same week in prior years.
z = (p − μ) / σ over the same calendar week, 5 yr (min 3)
e.g. A reading 2σ above the same-week mean → z = +2.0, which normalizes to ≈ 88 / 100.
How fast the price is moving, blending short-, medium- and longer-horizon momentum.
0.5·WoW% + 0.3·4wk% + 0.2·12wk%
e.g. +10% WoW, +5% 4-wk, 0% 12-wk → VI = 0.5·10 + 0.3·5 + 0.2·0 = 6.5%.
Whether velocity itself is building or fading — the change in VI week over week.
AI = VI(this week) − VI(prior week)
e.g. VI rising from 4.0% to 6.5% → AI = +2.5 (pressure is accelerating).
How widespread the move is across the five PADD regions — broad moves carry more weight than isolated ones.
share of the 5 PADDs rising week over week
e.g. 4 of 5 PADDs rising → BI = 0.80, i.e. 80 / 100 normalized.
The composite and its zones
The headline RPI-C is a weighted blend. Range position carries the most weight (it is the most stable); the z-score and velocity are normalized to 0–100 via a logistic curve before weighting, and breadth contributes a final tempering factor.
RPI-C = 0.40·RPI + 0.25·norm(ZSI) + 0.25·norm(VI) + 0.10·norm(BI)
where norm(ZSI) = 100 / (1 + e^−z), norm(VI) = 100 / (1 + e^(−v/3)), and norm(BI) = 100·BI.
Validation back-test
Before going live, RPI-C is back-tested against seven seeded historical fuel-price regimes. The standard: every event must land within one zone band of its expected reading (none two or more bands off), and the 2022 Russia/Ukraine peak must read Severe (≥ 80). This pins the methodology to known outcomes and guards against silent drift after a data refresh.

| 2008 Financial Crisis Fuel Collapse | — | Severe Pressure | — | — | — |
| 2011 Libya / Arab Spring Spike | — | Severe Pressure | — | — | — |
| 2014–2016 Oil Bust | — | Very Low Pressure | — | — | — |
| 2020 COVID Demand Collapse | 2020-05-04 | Very Low Pressure | Very Low Pressure | 15.4 | ✓ exact |
| 2021–2022 Post-COVID Surge | 2021-11-15 | Elevated Pressure | Severe Pressure | 86.1 | ✓ ±1 |
| 2022 Russia / Ukraine Spike | 2022-06-20 | Severe Pressure | Severe Pressure | 95.4 | ✓ exact |
| 2026 Spring Event | 2026-05-04 | Severe Pressure | Severe Pressure | 93.8 | ✓ exact |
Pre-2012 events evaluate against the all-types diesel series (history to 1994); the ULSD 5-year trailing window is too thin before ~2012 (retail ULSD begins 2007). Same-week ZSI absorbs sustained regimes into its own baseline, so the z-score component can read modestly at a prolonged peak even when the composite is correctly Severe. Validation currently covers U.S. national diesel.
