Explain the Difference Between Mobil 1 and Mobil 1 ESP
What is the difference between Mobil 1 synthetic and Mobil 1 synthetic ESP for a Mercedes 3.0 liter diesel engine in a new 2007 Jeep Grand Cherokee Limited?
-- Bill Nejelski, St. Louis, MO
Answer:
ESP stands for Emission System Protection. This means the oil has been balanced to protect the Emission System better by reducing the amount of certain additive components that can cause premature failure of diesel particulate filters and other emission related equipment. These special low ash formulations are designed with lower levels of phosphorus and sulfur for improved emission system protection. However, Mobil 1 ESP Formula M 5W-40 is specifically designed for certain engines that have a diesel particulate filter or other equipment that demands this type of lubricant.
