Gas expected to be $4.00 a gallon come spring

Now if you're trying to find high octane fuel, just buy a bottle of octane booster, though I question how you can afford the car that needs it yet not the gas

Oh, and the thing about Octane Boosters is that they don't work. It's as simple as that, you would need about 15-20 bottles per tank to even make the volumeric efficiency change in octane for your liking. The only real way to get higher octane gasoline is to purchase it after it has already been brewed, or brew your own gasoline with the right mix of methane and other addatives.
