Is M1's 0-20 being discontinued?

Oh really?
It that's the case I'm sure Mobil would stand behind their product.
I hit two Wal-Marts yesterday looking for Motorcraft but it's all gone.
Mobil 1 0w-20 was on the clearance cart at one but I had them check the price and it was still $4.77 so I didn't get any. Frankly if they don't put the new 5w-20 in jugs for $20, I'm just going to put M1 5w-30 in the Taurus.

I'm not buying this, is Mobil saying that Ford and Honda engines have failed due to the M1? My neighbor is the Service Mgr at a local Ford store, I'll be asking him about this. Funny thing is, he unequivocally states that M1 0W-20 is some of the best stuff available for both the wife's Taurus and my older Expedition, especially in winter.
I'm using the 0W20 in a 5.4 F-250, Mustang GT, and a Taurus. I tested a couple of other weights because I have always been in the frame of mind thicker is better. Well, not so with these vehicles! I get better milage with the F-250, the GT revs free, and the Taurus is smooth as silk. I'll be moving right on to the Mobil 1 5W20 when I use my current supply of 0W20 up. I see Autozone has the 5W20 now. I suppose Wal-Mart will start receiving their 5W20 soon also. I'm sold on Mobil 1! Been using their products in a couple of our other vehicles for over 10 years now and I have no complaints.
I kinda believe this one. It could be two scenarios. One, alot of dealers here still use bulk 10w30 even in 5w20 specd engines. imagine their surprise, when a vehicle comes in using 0w20. 2nd, if dealers do use 5w20, vehicle comes in with 0w20, I haven't seen one of these manuals but are they wording it in a way that says "use 5w20 only" or something to that effect? I'm sure alot of dealers use this as an escapegoat from doing warranty work also.
The owners manual in my Saturn Vue with the 3.5L Honda V6 says something like "Use 5W-20 motor oil only!." I remember that it is very specific about what to use.
M1 0W-20 in 2004 Honda Element 5sp works great~ top mpg and low consumption with 10K oci
Well said and very very likely to be true. The new formulation will probably have a lower VI and be less dependent on VI improvers. One thing I did not like about the old 0W-20 became evident after plotting out the oil's viscosity versus temeprature on the standard logarithm plot (to make it linear). The 0W-20 was most likely loaded with VII unless it's basestocks had a naturally higher VI. Although I misplaced my graph, the 0W-20 was way flatter than the 5W-30 and even 0W-30 plots and similar if I recall to the 0W-40 grade. In other words, it was way (very much) thinner than the other Mobil 1 products at low temperatures but almost as viscous as the 30 weights at higher temperatures. The new product may end up with more viscous basestocks.quote:

Here's a theory for why the 0w-20 is gone from the lineup. Mobil probably didn't grab enough market share from the uneducated, oil-ignorant public at large. I'd bet that many well-meaning owners of Fords and Hondas shied away, afraid that this stuff was "too thin" for their 5w-20 cars (). Then, as the new line is brought out, clearly with some tweaking to the formulae, Mobil just decided to "go with the flow," and make the revised product a 5w-20, so as to attract more of the Ford/Honda market. My final layer of speculation is that since brewing oils is inherently a game of balancing compromises, Mobil optimized some other parameter and in so doing, gave away a few degrees of ultimate low temp performance. Anyone's geuss as to whether this new formula would still "qualify" as a 0w-20 if Mobil wanted to label it as such. I've got a sneaking suspicion that it probably would. Again, this is just a possible scenario that might explain what's going on. And then again, it might be totally wrong.

1911,
If you should ever find this linear chart I would be very interested in seeing it. I would like to be able to determine between oils with great natural VI and those that use improvers.

Thanks Bryan,
Thank the Zoom Zoom man for the data (I guess he owns a Mazda or two)!!! The data I made the chart from was posted by Zoom Zoom on a previous post as shown below. Just plot them on an Excel spreadsheet and if you wish to quasi-linearize them, take put the viscosity (Y axis) on a logarithmic scale (comments below by Zoom Zoom himself):
This table will show you difference in viscosity at these given temperatures. 5W and 0W will flow quite a bit faster then M1 10W...
What surprizes me is that M1 5W will flow better then GC and M1 0W-40???

Thank you plugging it into excel right now
Thanks Bryan,
Can you post the chart as an attachment when you get done? It would be great for all to see. Also, your chart will also demonstrate to the self and BITOG post deluded that the procedure of using the numerical "spread" to determine propensity towards VII is bogus. For example, the 0W-20 has less spead than the 5W-30!!!!
