## When to Buy Gas in Texas: Morning vs. Night

The best time to buy gas in Texas is **early morning between 7 AM and 8 AM or late at night**. Here's why: fuel is denser when temperatures are cooler, which means you get more fuel for the same price.

### How Temperature Affects Your Gas Purchase

Gas stations store fuel in underground tanks. When it's cooler outside, the fuel is denser and takes up less space. When temperatures warm up during the day, fuel expands and takes up more space. This means:

- **Early morning or late night**: You're getting more fuel per gallon
- **Midday (10 AM to 3 PM)**: You're getting slightly less fuel for the same price
- **Annual savings**: The timing difference can add up to about $0.10 per gallon over a year

### Best Days vs. Worst Days

Beyond time of day, the day of the week matters too. Gas prices in Texas follow a pattern called "price cycling."

| Day | Price Level | Why |
|---|---|---|
| Monday | Lowest | Best time to fill up |
| Tuesday-Wednesday | Low | Still good options |
| Thursday | Highest | Most expensive day |
| Friday-Saturday | High | Weekend travel increases demand |
| Sunday | Varies | Can be cheaper but inconsistent |

### Why Days Matter

More people drive on weekends, so gas stations increase prices on Fridays, Saturdays, and Sundays to make higher profits. If you can, fill up earlier in the week (Monday through Wednesday) when demand is lower and prices are cheaper.

### Your Action Plan

1. **Plan ahead**: Fill up your tank on Monday, Tuesday, or Wednesday
2. **Pick the right time**: Aim for early morning (7-8 AM) or late evening
3. **Avoid peak times**: Skip Thursday through Sunday if possible
4. **Track patterns**: Gas prices in your area may follow similar cycling patterns

Combining both strategies (right day + right time) gives you the biggest savings on fuel costs throughout the year.
