John Oldner, an attorney in Murphy with a diesel truck, practices family law from a home office. Let's hope that office is not too close to where he used to turn used cooking oil from a McKinney café into biodiesel to fuel his truck -- chances are the french fry smell has yet to depart. In a Dallas Morning News story, Murphy, 71, explains how he made his own fuel at home before he found a "secret source" to supply his needs. He now pays $2.55 a gallon.
