Is Filling Up Gas in the Morning Really More Worth It?
Many people who drive regularly—whether using a personal car, monthly rentals, or Car Rental Bangkok services—have probably heard the common belief: “If you want better value, fill up your gas in the morning or when the weather is cool.” This idea is often shared among users of Rental Car services, pickup truck rentals, and even Van Rental Bangkok customers. But how true is it in real life?
The concept comes from basic physics: liquids become slightly denser at lower temperatures. Because of this, fuel in cooler weather is often assumed to be more “concentrated,” leading people to believe that filling up in the morning provides more energy than filling up during the hot daytime. That’s why many users of Car Rental, including long-term renters, prefer to refuel early in the day.
While fuel density does change with temperature, the difference is extremely small—usually around 0.2–0.5%. More importantly, fuel at gas stations is stored in underground tanks, where temperatures remain relatively stable throughout the day. As a result, whether you refuel in the morning, afternoon, or evening, the actual amount of fuel you receive is almost the same. For frequent users of Car Rental Bangkok or Van Rental Bangkok, this difference has virtually no noticeable impact on fuel costs or driving range.
What Matters More Than Refueling Time
Instead of focusing on the time of day you refuel, it’s far more effective to pay attention to:
- Driving habits
- Vehicle condition
- Choosing the right car for your usage
For anyone relying on Rental Car or long-term Car Rental services, selecting a fuel-efficient, well-maintained vehicle can make a real difference in long-term expenses.
If you’re looking for a reliable Car Rental Bangkok provider or a convenient Van Rental Bangkok option, ecocar rent-a-car offers a wide range of vehicles—from fuel-efficient compact cars to vans and commercial-use vehicles. All vehicles are regularly maintained and ready for real-world use, helping customers manage fuel and maintenance costs more effectively—whether for personal travel or business needs. In summary, filling up gas in the morning may sound more economical, but in real life, the difference is barely noticeable. Choosing the right Car Rental service and the right vehicle—like those from ecocar rent-a-car—is what truly helps you save in the long run.
