- **Driving Season Demand** — Memorial Day to Labor Day is peak driving season. Demand rises, prices often follow.
- **Inventory Levels** — EIA weekly reports on gasoline stocks move prices. Low stocks = bullish.
- **RVP Regulations** — Summer gasoline requires lower volatility, more expensive to produce. Seasonal price premium.
- **Ethanol Costs** — Ethanol (10% of finished gas) costs affect final price. Corn prices matter.

A: State taxes, transportation costs, and environmental regulations vary. California has the strictest rules and often the highest prices.

**Q: What is the crack spread?**

A: The difference between crude oil cost and refined product prices. A wide crack spread means refineries are profitable.

**Q: Why do gas prices rise before holidays?**

A: Anticipation of increased driving demand, plus refineries may reduce output for maintenance before peak season.

**Q: How do hurricanes affect gas prices?**

A: Gulf Coast refining capacity can be shut down during hurricanes, reducing supply and spiking prices nationwide.

**Q: What is summer blend gasoline?**

A: Gasoline with lower Reid Vapor Pressure (RVP) to reduce evaporative emissions. It's more expensive to produce than winter blend.

**Q: How much of gas price is taxes?**

A: Federal tax is 18.4 cents/gallon. State taxes range from 14 cents (Alaska) to 68 cents (California). Total tax is typically 15-25% of pump price.
