Startup Idea: Gas Siphon

A marketplace where you can list what gas is in your auto and what you paid. For example 91 Octane $2.81 a gallon. Someone else can offer to buy it. A trusted gas siphon person probably wearing a badge shows up to take from your tank and fill the other. Financials: - estimate the average consumer can sell 10-15 gallons a week - 5% markup - if you buy gas on a gas card you can easily net 10% per gallon sold. Thats gonna be cash in your pocket. - You can make $50-100 or more a month! - The more cars you own the more you can profit - Like airbnb millions of eligible personal autos - I have to pay the guy to siphon gas one tank to another. Cover with nominal set of fees like DoorDash (average order is 50% fees and people pay it) Honestly this works.
