LUBRIZOL ANNOUNCES STRONG PRELIMINARY
FIRST QUARTER 2007 RESULTS

CLEVELAND, Ohio, April 13, 2007 — The Lubrizol Corporation (NYSE:LZ) announced that it expects to report strong earnings performance for the first quarter of 2007 of approximately $1.00 per diluted share, including a restructuring credit of approximately $.02 per diluted share.

In the first quarter of 2006, the company reported earnings from continuing operations of $.66 per diluted share, including a restructuring charge of $.02 per share. Excluding the restructuring charge, adjusted earnings from continuing operations for the first quarter of 2006 were $.68 per diluted share. Comparable adjusted earnings from continuing operations for the first quarter of 2007, excluding the restructuring credit, are expected to be in the range of $.98 per diluted share. First Call analyst earnings consensus is currently $.78 per share.

The strong performance compared to the first quarter a year ago was primarily the result of higher revenues, driven by the improvement in the combination of price and product mix. In addition, shipment volumes in the quarter were higher than expected, and reflected a return to normal order patterns.
