About

A calm, data-backed answer to a weekly question.

Should I Fill Up? is a lightweight tool designed to help drivers decide whether they should refuel today or hold off for better prices.

The problem

Gas prices move weekly, but most drivers only get a vague sense of when to fill up. That uncertainty adds up over time.

The solution

Should I Fill Up? combines two years of EIA data with live station pricing to recommend whether you should fill up now or wait.

How the model works

We look at trend direction, recent volatility, and how much fuel you have left. The recommendation balances savings against running low.

Data sources

Historical pricing comes from the U.S. Energy Information Administration (EIA). Optional station pricing uses GasBuddy data when available.

Transparency and limitations

Should I Fill Up? provides guidance, not guarantees. Price movements are influenced by regional events, supply constraints, and market shifts outside the model. Always use your best judgement for safety and scheduling.
