Frequently Asked Questions

Gas stations in Lewiston typically update prices 1-3 times per week in response to wholesale market changes. Prices generally dip early in the week and rise Thursday-Sunday. Following weekly trends helps identify optimal fill-up windows.
Costco and Sam's Club fuel stations serve many major metropolitan areas and offer the lowest prices for members — typically 15-25 cents below local market. Membership costs $65-130/year but typically pays for itself in fuel savings alone for regular drivers.
Gas price spikes in Lewiston are typically triggered by regional supply disruptions, pipeline outages, refinery maintenance, seasonal blend transitions, and global crude oil price increases. Holiday demand surges around Memorial Day, July 4th, and Labor Day also push prices up temporarily.
Premium gas in Lewiston is worth the extra cost only if your vehicle requires it. If your owner's manual says Required, always use premium. If it says Recommended, you may use regular with minimal performance loss. Never use regular in a vehicle that requires premium.
Costco offers the cheapest gas wherever it operates in the Lewiston area. Among street stations, Circle K, Speedway, and Wawa (in applicable markets) consistently offer below-average prices. Shell, Chevron, and BP typically price above the local average.
