Mobil 1 0w-40 being replaced

WOOCHOW · Dec 31, 2006

Here is a blurb from a Mercedes-Benz TSB
Recent oil TSB:

"Mobil 1 ESP Formula M 5W-40 is formulated to meet the latest Mercedes-Benz engine oil specification MB 229.51. This new formulation is designed to offer high levels of performance for Mercedes-Benz diesel and gasoline engines as detailed in the Dealer Technical Bulletin P-B-18.00/17d dated April 13, 2006."

"Mobil 1 ESP Formula M 5W-40 replaces Mobil 1 OW-40, and will be provided to dealers based on deployment through ExxonMobil distributor network."

"To prepare for the transition you must draw down Mobil 1 0W-40 bulk tanks to a minimum 20% level in preparation for the new product."

Interesting. I wonder if the product is only sold in bulk?

I like how they are going to fill up the tank that still contains 20% of a different viscosity/formulation. And we worry about whats left in the engine after a routine oil change.

Guys, read my older posting about this mixing subject .It doesn't make any difference . Where do some get their ideas?

Its simple, the 0W-40 does not meet DC 229.51. MB has decided after consulting with Mobil that a 80/20 Mix with 0W-40 will still allow the 5W-40 to meet the performance requirements of 229.51 for the vehicles that require it.

does not have many approvals yet, but I wonder if it will be replacing 0w-40 across the board... It would need to meet GM-LL-025-A for that to be the case, of course Mobil could just leave us Saab owners hanging...

Of course if it is designed for applications and viscosity retention behavior like the 0w-40 did (especialy in engines where it was not designed/did not belong), then people will badmouth this like the 0w-40, and folks will start to look down upon 5w-40 oils... oh well.

Isn't 5W-40 more widely spec 'd by the manufacturers? If so it makes sense for Mobil to change, just as they did at one time by adding 5w-20 after they first came out with 0W-20.

I know Torco dropped their 10W-40 in favor of a new 5W-40 for the same reason. You have to make a product that jives with the numbers the car makers put out. Most consumers shop that way.

If you remove GIV out of the mix would you then not be able to cover the spread to make a 0w-40 oil and still pas MB specs.

I take this as this oil is being replaced at MB dealerships...not replacing the oil on the entire market. Right?

That is my understanding.

I've seen in it quart bottles. Same store also had Mobil 1 5W-50.

JMH, what cars besides the new 9-3 require the GM-LL-025-A spec? Is it all the forced induction Ecotecs or what?

I agree that it only makes sense for Mobil to come out with a 5W40 b/c of people who don't understand oil viscosity ratings.
