Brewing illegal whiskey in a bathtub out back is so eighty years ago. These days, backyard stills in California are much more likely to be turning stolen restaurant grease into barrels of bootleg biofuel. Now that gas prices have gone up, a car that runs on used fryer oil sounds increasingly appealing.
Unfortunately, this means that grease-haulers are losing thousands of dollars a year, prompting those in the business to look into locking their trash cans. But even locked barrels of grease are disappearing into the gas tanks of Californian cars. It's no wonder, considering that the price of soybean oil has tripled in the last three years. The liquid dripping off your French fries has never looked this good.
