Mobile 1 No Longer Recommended by MB?
OK, so I go to my authorized MB Dealer/Service Center today to have oil & filter changed on my 2005 C55 AMG.
I asked the service manager if they would use 0W-40 Mobile 1 Synthetic. I was told that they do not use Mobile 1; I was also told that MB has instructed the dealership to use Castrol Synthetic. I mentioned my manual and the car has stickers everywhere to use Mobile 1, and they said they know. As I sat in the waiting room, reading the latest MB Magazine, there is a giant ad about MB and Mobile 1. As the car was being finished up, I chatted with the mechanic, and asked what oil they used. He said Castrol Synthetic. I asked what weight, he said 0W-30.
So, my manual and warranty book says only the following is approved:
Mobile 1 SuperSyn 0W-40
Penzoil Ultra 5W-30
Quaker State Ultra 5W-30
Castrol is NOT listed. I asked 5 times between the service manager and technician and they always said Castrol for my AMG.
So... I am confused as heck as to why a MB dealership is using an oil not listed in my manual as being approved... and why, after my 2005 car has Mobile 1 stickers on it, MB would change its mind about Mobile 1.
Maybe I shouldn't be so paranoid about oil brand/weight... but I thought with a "high quality car" there would not be this kind of issue. Not to mention the manual says stuff about the warranty not being there if you don't use proper oil.
Any advice is appreciated!
