Lubrizol Announces Strong Preliminary

Second Quarter 2009 Results

CLEVELAND, July 15, 2009 – The Lubrizol Corporation (NYSE: LZ) announces that it expects to report earnings performance for the second quarter of 2009 of approximately $1.92 per diluted share, including a restructuring and impairment charge of approximately $.10 per diluted share. Excluding this charge, the company expects to report earnings as adjusted of approximately $2.02 per diluted share.

Lubrizol will release complete second quarter 2009 earnings and revised full-year earnings guidance on Thursday, July 30, 2009 at approximately 8:00 a.m. Eastern time. The company will conduct its earnings teleconference with analysts and investors at 11:00 a.m. Eastern time the same morning.

Earnings as adjusted (Non-GAAP) is a measure of income that differs from earnings measured in accordance with generally accepted accounting principles (“GAAP”). Earnings as adjusted (Non-GAAP) is net income attributable to The Lubrizol Corporation per the company’s consolidated results, adjusted for the exclusion of restructuring and impairment charges. Management believes that both net income attributable to The Lubrizol Corporation and earnings as adjusted for exclusion of these special charges assist the investor in understanding the results of operations of The Lubrizol Corporation. In addition, management and the Board evaluate results using net income attributable to The Lubrizol Corporation and earnings as adjusted.
