When should I fill up gas in Austin to save money?
Fill up on Tuesday midday or Wednesday morning in Austin. These times offer the lowest weekly prices. Demand rises toward the weekend, so prices climb then.
Key Times to Save
Here's what you need to know:
- Tuesday around noon: Prices hit weekly lows before demand picks up.
- Wednesday morning: Still low before midweek shifts.
- Avoid late week: Prices creep up as Friday and Saturday approach.
| Day | Best Time | Why It Saves |
|---|---|---|
| Tuesday | Midday (11am-2pm) | Lowest prices before demand rise |
| Wednesday | Morning (before 10am) | Weekly low before increases |
| Avoid | Thursday-Sunday | Higher demand pushes prices up |
According to local Austin gas trends, you find the lowest prices of the week at midday on Tuesday and on Wednesday morning (Source: Oxford at Tech Ridge Blog, 2023). Other factors like global oil prices or holidays can shift this, but these days give your best shot week to week.
Time of Day Tips
You may get slightly more gas in cooler hours. Gasoline expands in heat, so pumps might deliver less volume on hot afternoons. Consumer Reports tested this. They found the first gallons from the nozzle run warmer from sun-heated pumps. Wait a few seconds, and fuel cools by 8°F to 17°F.
"Today's double-walled tanks keep fuel warm if delivered warm," says Rich True, CR's test track manager (Source: Consumer Reports Fuel Test, recent). Fill early morning or evening for cooler temps. But in Austin's 78701 heat, focus more on the day.
