The fluctuation of oil price is influenced by many factors, including the relationship between supply and demand, geopolitical factors and market expectations. Deciding whether to wait for the oil price to drop before refueling is a personal choice, usually based on the financial situation, traffic demand and the judgment of the oil price trend.

For individuals with cars, the following points can be considered:

1. Demand and urgency: According to your actual flow demand and remaining fuel tank, evaluate whether you can wait for the oil price to be lowered. If you have enough oil, and the change of oil price is not a big burden on your economy, you may be able to wait.

2. Oil price forecast and market analysis: Pay attention to the forecast and market analysis of oil prices by the media or professional organizations in order to make more informed decisions. This can help you to know whether it is possible to lower the oil price and refuel at the right time.

3. Economic considerations: Considering your own economic situation and budget, whether the predicted oil price changes will have a significant impact on personal finance. If saving a few copper coins is not important to your economy, it may not be worth waiting for oil prices to fall.

Whether to wait for the oil price to come down before refueling is a personal decision. It is necessary to comprehensively consider various factors and weigh your actual needs and economic situation. It is recommended to make a reasonable choice according to personal circumstances.
