## Diesel Margins Soar
Phillips 66 reported $29.56 per barrel diesel margins in Q2 2026, up from $10.11 the prior quarter.

> Diesel margins just ran five times their normal range as Russian barrels vanished and Gulf throughput cratered.
## Why Margins Spiked
Russian oil exports collapsed and Gulf shipments fell, causing a supply shock that lifted diesel margins to $29.56 per barrel.

> You've had significant refining capacity offline and stocks are low.
## Refining Impact
Phillips 66 generated $52.04 billion in revenue and $9.41 adjusted EPS for Q2 2026, beating consensus.

> Refining drove the quarter: worldwide realized margins jumped to $24.08 per barrel.
## Competitor Margins
Marathon Petroleum reported $36.33 per barrel refining margins, while Valero Energy hit $43.52 per barrel Gulf Coast diesel margins.

> Valero Energy reported a blended refining margin of $23.62 per barrel and a stunning $43.52 per barrel ULS diesel margin.
## Long-Term Risk
Diesel margins could drop if Russian oil returns and Gulf shipments recover, but structural refinery closures may keep margins high.

> The geopolitical layer can normalize. If Russian barrels return and Middle East throughput recovers, the diesel dislocation compresses fast.
## Key takeaway

Diesel margins hit $29.56 per barrel due to Russian barrel shortages and Gulf shipments dropping.
