油價助手：下週油價預測

"Should I fill up today, or wait until next week?"

The Oil Price Assistant is more than just a price check app; it answers the real decision you need to make before filling up.

■ Next Week's Oil Price Forecast CPC Corporation announces its oil price every Sunday at noon, effective Monday at midnight. This app calculates the possible price fluctuations for next week based on the Ministry of Economic Affairs' publicly released floating oil price formula (70% Dubai crude + 30% Brent crude, pricing period from last Thursday to this Wednesday), helping you decide whether to fill up today.

■ Honest Disclosure of Accuracy We present each week's "forecast" alongside the "actual announcement," allowing you to judge its accuracy for yourself. CPC Corporation often uses the stabilization fund to "freeze prices"—the formula calculates an adjustment, but the actual adjustment doesn't occur. We also clearly indicate these situations, without using fancy numbers to embellish the accuracy rate. Next week's price is an estimate, not an official figure; the actual price is always based on the announcement each Sunday.

■ Three Brands' Fuel Prices at a Glance
Compare 92/95/98 unleaded and premium diesel from CPC, Formosa Plastics, and Costco side-by-side on one page. (Costco does not publish real-time fuel prices; its prices are estimates based on CPC's equivalent fuels minus a fixed difference, clearly indicated within the app.)

■ Nearby Gas Stations and One-Click Navigation
Shows the nearest gas stations based on your location. Filter by fuel type, brand (CPC/Formosa Plastics/Costco), self-service, and car wash availability. A single click opens map navigation.

■ Fuel Price Trends and Levels
Provides charts of the four fuel types' price trends over the past six months, showing where the current price falls within a range—relatively cheap, average, or expensive.

■ Desktop Widgets and Reminders
The desktop widget directly displays this week's fuel prices and next week's forecast. Thursday's forecast reminder and Sunday's announcement reminder can be enabled.

■ About Permissions
Location permissions are only used to calculate the nearest gas station on your device and are not transmitted or stored. You can still check prices and view forecasts without authorization.
