Comparing oil collections [Photo]

Scott Schulte holds up two samples of used cooking oil to compare their quality in the garage of his Columbia home on Friday. The clear one on the right is of good quality. The brown one on the left has been used extensively before being exchanged and contains many impurities and solids. "Some restaurants clearly want to make the most out of their oil," Schulte says with a smile.

To keep track of where he gets the best oil from, Schulte keeps a collection of samples in his garage. Some restaurants use their oil more extensively than others, leaving it contaminated with many impurities and solids when Schulte picks it up.

Scott Schulte of Columbia leans against the back of his vegetable oil-fueled truck in the garage of his home on Friday. In January 2008, Schulte, a retired park superintendent of the Rock Bridge State Park and a section of the Katy Trail, started his business called Biofuels, where he sells filtered and purified vegetable oil that can be used as a diesel substitute in specially prepared cars.

Scott Schulte demonstrates his homemade straight vegetable oil filter system in the garage of his Columbia home on Feb. 13. Schulte, a retired park superintendent of the Rock Bridge Memorial State Park and a section of the Katy Trail, buys old cooking oil from restaurants in the area and filters out impurities and solids to fuel his 2006 Chevrolet Duramax pick-up truck. Since January 2008 Schulte has also been running a business called Biofuels, where he sells the purified vegetable oil.

Scott Schulte equipped the interior of his van with an interconnected array of tanks, pumps and hoses that allows him to collect the used cooking oil from the restaurants in a 100-mile radius around Columbia. "I want that protection," Schulte said about why he built the system in the van. "It's hard to keep your stuff nice and clean when it's exposed to the elements."

Manage the flow of diesel [Photo]

The fuel injection control module and the Pollak 6 port valve are located in the bottom left corner. The control module is the silver block, the valve is the black box attached to it. Both are part of the Golden Fuel system in Schulte's car that manage the flow of diesel and the filtered and heated straight vegetable oil (SVO) stored in the tank on the back of the truck into the engine. When Schulte starts the engine of his Chevrolet, it runs on regular diesel until it reaches operating temperature. The hot coolant can then be used to heat the more viscous vegetable oil in the tank. Once it is heated up properly, Schulte flips a switch on his dashboard and the car runs on SVO.
