Avi Salzman — Trump's Latest Gasoline Move Could Cut Prices—and Increase Smog
The EPA lets stations switch to cheaper winter-grade gasoline two weeks early — worth 10–30¢ a gallon for a few weeks, against a $4.11 pump price that is $1 above a year ago because of the wars, not the blend.
One-line take: A short, policy-mechanics piece with one investable clause. The EPA is allowing stations to sell cheaper winter-grade gasoline from Sept. 1 rather than mid-September — permitting E10 blends with more volatile components like butane, which are cheaper to produce and could put "hundreds of thousands of extra barrels of gas per day" into the market, worth 10–30¢ a gallon (AAA) in early September. The trade-off is environmental: winter fuel evaporates more readily, so the early switch "can contribute to increased smog." Salzman is careful to bound the relief. The waiver is federal and states can be stricter — California and New York haven't waived many of their own rules this year despite federal approval. And even where it is adopted, "consumers may only see modest relief": the reason the average price is $4.11, about $1 above a year ago, is that "oil and fuel supplies have been strained by the wars in Iran and Ukraine." The single equity sentence closes the piece and corroborates the Aug 18 refining thesis: "Refiners like Valero and Marathon Petroleum are making very high margins on the fuel they sell amid elevated prices at the pump." Note the direction of the policy: a cheaper, higher-butane, higher-volume blend relaxes a constraint on refiners rather than taxing them — the pump price falls without the crack necessarily following. (Reportage, not a personal call; the two refiners are marked Positive on the margin statement, consistent with the Aug 18 framing.)

| VLO | Valero Energy | QT · SA · STK · FA | Positive | Named first in the article's only equity sentence: refiners "like Valero and Marathon Petroleum are making very high margins on the fuel they sell amid elevated prices at the pump" — with the average gallon at $4.11, about $1 above a year ago because "oil and fuel supplies have been strained by the wars in Iran and Ukraine." The policy itself is refiner-friendly at the margin: the EPA is permitting a cheaper-to-produce winter blend (E10, more butane) two weeks early, which lets more volume clear — a relaxed constraint, not a windfall tax. | read ↗ |
| MPC | Marathon Petroleum | QT · SA · STK · FA | Positive | The second refiner named as "making very high margins on the fuel they sell amid elevated prices at the pump." The framing matters as much as the fact: the administration's lever against $4.11 gasoline is a blend waiver worth 10–30¢ for a few weeks, not an action against refining margins — and its reach is limited because "states often have tougher requirements" (California and New York have declined to waive many of their own rules). Confirms the Aug 18 margin thesis three days later, on the gasoline side rather than diesel. | read ↗ |
2. Talking points
The move — winter-grade gasoline two weeks early
- The EPA is allowing gas stations to switch to cheaper winter-grade gasoline starting Sept. 1, "rather than waiting until mid-September as they usually do."
- Framed as "the Trump administration's latest move to tamp down gasoline prices," which "could cut 10 to 30 cents a gallon in early September, though the effect is unlikely to last long."
The mechanics — E10, butane and volatility
- The waiver lets refiners sell E10, a gasoline blend containing 10% ethanol.
- Winter-grade gasoline "can contain more volatile components, including butane, which helps fuel evaporate more easily in colder temperatures. It is also cheaper to produce."
- Butane is the cheap blendstock summer rules exclude — allowing it back in both lowers input cost and stretches each barrel further.
The volume effect — extra barrels per day
- The EPA said the relaxed rules "could allow stations to sell hundreds of thousands of extra barrels of gas per day, potentially reducing prices."
- AAA: winter fuel "can be 10 to 30 cents cheaper than summer fuel."
The starting point — $4.11 and $1 above a year ago
- "The average gasoline price is $4.11 per gallon, about $1 above a year ago, according to AAA" — the scale that makes a 10–30¢ waiver a partial offset at best.
The trade-off — more smog
- "Because winter-grade gasoline evaporates more readily than summer fuel, it can contribute to increased smog."
- "The government normally requires stations to stick to heavier and less-volatile gasoline blends in the summer for environmental reasons" — the rule being waived exists precisely because late-summer heat plus volatile fuel makes ozone.
The limit — a federal waiver into a patchwork of state rules
- "The EPA's fuel waiver applies nationally, but states often have tougher requirements."
- "California and New York, for instance, haven't waived many of their gasoline rules this year, despite federal approval to do so" — the two largest strict-blend markets opting out blunts the national average effect.
Why relief stays modest — the wars are the price
- "Even in states that adopt the new EPA standards, consumers may only see modest relief from high prices."
- "Oil and fuel supplies have been strained by the wars in Iran and Ukraine, a major factor keeping prices elevated" — a blend-specification change does not address a supply shortage.
The equity read-through — refiners keep the margin
- The closing sentence: "Refiners like Valero and Marathon Petroleum are making very high margins on the fuel they sell amid elevated prices at the pump."
- Note what the policy is not: it is not a price cap, an export restriction or a windfall levy. It permits a cheaper blend at higher volume — relief aimed at the consumer that leaves the refining margin intact, and arguably helps it.
- The three-day sequel to the Aug 18 record-crack piece: same margin story, gasoline instead of diesel, now with the policy response visible and unthreatening.
3. In plain English
A jargon-free summary of how each name is framed in the article. (Plain-language companion to the table above; renders on the ticker's consolidated page.)
VLO — Valero Energy Positive
Gasoline is not one product. In summer the government requires a heavier, less evaporative blend because fumes in the heat make smog; in winter refiners are allowed to mix in cheap, volatile ingredients like butane. The winter recipe costs less to make and stretches further, so the same crude yields more sellable gallons.
The EPA has just let stations switch to that cheaper winter blend on Sept. 1 instead of mid-September. For drivers it is worth maybe 10 to 30 cents a gallon for a few weeks, against an average price of $4.11 that is a full dollar higher than a year ago. For a refiner like Valero it is the opposite of a crackdown — it is permission to sell a cheaper-to-produce fuel in greater volume.
The article's last line is the part that matters for the stock: refiners "like Valero and Marathon Petroleum are making very high margins on the fuel they sell." That is the same story as the record diesel margins three days earlier, and the political response to it so far is a blend waiver rather than anything that touches what refiners earn. The reason pump prices are high is the wars in Iran and Ukraine straining supply, and a change in fuel recipe does not fix a shortage.
MPC — Marathon Petroleum Positive
Marathon is named alongside Valero as earning very high margins on the fuel it sells while pump prices stay elevated. Nothing in this piece changes that — the government's move is aimed at the price consumers pay, not at refiners' profits.
Two limits are worth holding onto. First, the waiver is federal, and states can be stricter: California and New York have declined to relax many of their own gasoline rules even when allowed to, so two of the biggest markets see little of the benefit. Second, the relief is temporary by construction — the switch would have happened two weeks later anyway.
The useful signal for a refinery owner is what the policy toolkit currently looks like. When politicians want cheaper gasoline and reach for a blend waiver rather than an export ban, a price cap or a windfall tax, the margin is not yet the target. That is the thing to watch: the tool changing, not the pump price.
