also is this true?;; Diesel engine requirements are much different that those of gasoline engines. The higher speeds and lower bearing surface-to-power ratios of gasoline engines require oil with higher shear ratings than most diesel oils. Diesels also have higher bearing clearances and that calls for higher viscosity oils. The additional detergents required for soot control actually reduce the effectiveness of added levels of ZDDP found in diesel oils. Also, newer diesel oils beginning in 2007 have greatly reduced their content of ZDDP In a message dated 7/12/2008 8:37:19 A.M. Central Standard Time, [EMAIL PROTECTED] writes:
Harlan, I just got through reading the thread that Bill sent. I work for Chevron Oronite Company, we are a Petrochemical part of Chevron. That is the part of Chevron that manufactures the additives that go into lubricating oils. Many other companies use our additives in their engine oils. I use the DELO, D-iesel E-ngine L-ubricating O-il, because it still contains the sufficient amount of Zinc and Phosphorous to protect our flat tappet engines. Along with the Zinc and Phosphorous there is also a small amount of Moly in this oil. Reading the thread just reaffirmed my belief in the products that we make and sell at COC.
