Question:
Difference between 5W-40 Products
My Mercedes-Benz dealer uses Mobil 1 ESP Formula M 5W-40. Is there a difference between the ESP Formula M from the dealership and the Mobil 1 Turbo Diesel Truck 5W-40 for diesel trucks I see at the local auto parts store?

Answer:
Yes, these are totally different products designed for different requirements.
