Postl figures he can wring 2% to 3% annual growth out of the business simply by increasing advertising and exploiting the company's relationships with retailers and fast-lube chains.

Postl's company also owns the biggest of those chains, Jiffy Lube, which will expand to more than 2, 000 U.S. outlets after Quaker State's Q Lube chain is folded into it later this year.

All that market power should give Postl leverage with retailers like Wal-Mart, one of Pennzoil-Quaker State's biggest customers, when he wants to squeeze smaller brands off the shelves to make more room for Pennzoil and Quaker State.
