 | | Question: | | Can Mobil 1 Turbo Diesel Truck be Used in Place of Mobil 1 ESP Formula M 5W-40? | | We have a 2007 Mercedes ML320 CDI (diesel) SUV. The owner's manual calls for Mobil 1 ESP Formula M 5W-40 oil, which is hard to find locally. I can readily find Mobil 1 Turbo Diesel Truck 5W-40, which says on the label that it is "recommended for virtually all diesel-powered equipment from U.S., European and Japanese equipment builders. . ." But, nowhere is Daimler Chrysler mentioned on the label. I compared the properties specs for both. There are some differences. Is the Turbo Diesel Truck oil of equal or better quality than the ESP Formula? If I use the Turbo Diesel and have a problem with the engine later, would Mercedes have a basis to claim that I used an inferior grade oil to that demanded in their MB 229.51 spec? Thanks. | | -- Marvin Vanhise, Lawrenceville, NJ |  | | Answer: | You should use the MB 229.51 recommended product.
