0w40 shearing is not necessarily a bad thing.

I may do the same on a supercharged 5.4L; using straight M1 5W50 right now.

ok so i'm not too crazy. i got the idea from your voa too. thanks for that post. and after some searching i found that petroalliance is here in cleveland. so i drove and picked up a case of 5w50 yesterday. i plan to do my oil change with the 50/50 mix today.

Did you get the SM or SN variety of the 5W50?
i got both viscosities in the sn variety. i put them in a couple hours ago along with napa platinum filter. i just bought the car so i'm not sure what was being run. after seeing the voa's for both of these oils i'm pretty confident that this should be a good combo.

It would be nice to have a VOA of the SN 5W50 to see if Mobile retained the previous Calcium rich formula rather than the new SN Calcium/Magnesium formula like they did for the 15W50.

Can't draw any other conclusion. This is a global benchmark oil.

I also took advantage of the local wholesaler in Cleveland (PetroAlliance) and replenished my supply of M1 5w50 for my Porsche Cayman S. It sees pretty regular track use at Mid-Ohio in the summer, so I wanted a Porsche A40 approved 50 weight oil...which M1 5w50 is.
Anyway, I got 4 cases ($38/case!!) and they were all API SN. I changed the oil last night and sent in a VOA of the SN formulation and a UOA of the SM formulate that I removed from the engine. I'll be sure to post both results when I get them.
Thanks,
Matt

thanks for sending in the voa of 5w50. i'm anxiously awaiting it to see it.

I appreciate seeing this SN 0w40 VOA!
I am about to replace my SM 0w40 in Mercedes with SN and was a bit nervous about what has changed.
I'm glad to see it looks nearly identical.

Great additive package.
ILSACs limits on ZDDP (phosphorus/zinc) and ash only apply to xW-20 and xW-30 grades.
High initial TBN and detergent (calcium) level is because this is a Euro super-extended-drain oil (25000+ miles) -- that is the A3/B4 (not the A3/B3) category.
Thanks for the VOA.

I love the generous amount of ZDDP and the generous initial TBN value, along with the proven high-quality Mobil 1 fully synthetic basestocks.
This would be a great oil for those seeking lower engine-wear rates and long oil-change intervals (well in excess of 10,000 miles). The only caveat is some loss in fuel economy and horsepower due to high HTHS viscosity.

The main difference with the SN vs SM oil is that the base oil chemistry and/or VIIs has been improved resulting in a lower KV100 and higher HTHSV of 3.8cP vs the SM's 3.7cP and a higher KV100.
The end result is a somewhat heavier and likely more shear resistant oil.

Lots of 30-weight apps. could use that without the slightest issue.
Great points addguy. I've got a couple of changes worth on my shelf just itching to get in my Speed3 DI/turbo which is chewing up PP 5W-30 in 3-4,000 miles.

I don't think so. The current PDS info is unchanged.

That ones easy to answer. It costs them less to make the sn version with visom then the previous sm version that had a very high % of pao. The sn version has slightly worse specs however I believe that in actual use the difference would be imperceptible.
But it's all about money,and saving a few pennies per quart adds up really fast when multiplied by millions of quarts.
