[W126 Coupe] Oil for 560 SEC

[Kelly Frink]

Dear Kelly,

Zinc levels are being lowered on almost all engine oils, but the heavy duty
diesel engine oils, such as the Rotella T, will continue to have higher
levels than the passenger car/gasoline engine oils.  The Rotella T 15W-40
meets API SL, SJ, SH and all previous specifications for gasoline engines.
Although the amount of zinc is decreasing, the wear protection will continue
to be as good or better than the previous formulations.  We are just using
different chemistries in the additive package.  The 15W-40 viscosity is
heavier than what is recommended for most gasoline engines, but if you feel
comfortable with it, then there should be no problem.  Rotella T 15W-40 is
recommended for and used in many mixed fleet applications.  It does have a
higher antiwear level to protect the heavy duty diesel engines and should
give you very good performance in this regard.

Thank you for your interest in our products!  If you have any further
questions, please call us at 800 231 6950.

Sincerely,
MaryCarol Boemmel
