A fuel pre-purchasing and sharing system (and associated methods) is disclosed herein. The system allows consumers to pre-purchase fuel at a pre-purchased price, and redeem pre-purchased fuel at a subsequent time regardless of the current price of fuel posted at the point of re-fueling. The pre-purchased price can be based on current fuel prices of fuel at one or more service stations that are near to a consumer at the time that the fuel is pre-purchased. Pre-purchased fuel of one or more grades of fuel can be held in a pre-purchased fuel tank. The pre-purchased fuel tank can be shared with other consumers such that the other consumers can redeem pre-purchased fuel held in the pre-purchased fuel tank.
