This scares and excites me at the same time! lol. (look in my sig!) I'm the only one (I know of) that runs M1 15w50 in my Mazdaspeed 3. Certainly no UOA's out there for it. And I've read some scary stuff about the oil pickups on my car are too small to circulate such a thick oil and properly lubricate the top end. Yet here I am... breaking boundaries and testing it out. My Universal Averages for my car is 4,500 miles, which is how long I plan on running it and pulling a UOA to compare. I guess we'll soon find out. As an aside, my car has NEVER run better on any other oil, and I definitely felt some oomph when I put it in.... something I've speculated as a boost in compression due to it's viscosity helping seal the loose rings (I've been guessing I have low compression for awhile now). I guess I'll see. Next up after this though is Royal Purple 0w40, which will also get a UOA, though I plan on taking it out to 9,000 miles (doubling up the UA's so I can divide by half). My car shreds oil though, so that's a bit scary as well.


M1 15W50 imo is one of the best oils made. It runs super smooth in any car I`ve ever tried it in. It also seems to be able to take a ton of abuse. It`s a very thin 50 wt,so I`ll run it during the winter,along with RP 15W40. It wont hurt your car at all,I`d just keep on using it.
 
Sweet. Thanks for the advice man. I suppose if my UOA of it comes back good I'll keep using it. Though I'm extremely tempted to run 10w30 High Mileage. Maybe that's an idea, run the 10w30 HM in the winter months and the 15w50 Racing oil in the summer months. What do you think of that idea? yay or nay?

Also, I live in N.E. Oklahoma and the winter can get pretty cold. Well below freezing many times usually. Will this be an issue for the M! 15w50 Race or 10w30 HM? Thanks!

Mobil 1 0w-40 base oil is mostly group III and the rest is PAO and has been for a while now, don't know when they changed (i got the info from the MSDS before you ask).

hope ths helps
 
It is good and is full PAO but has now been superceded by Mobil 1 extended life 10w-60 which is a similar mix of group 3 and 4 to the 0w-40
 
As far as i can find out from msds's both Mobil 1 ESP 5w30 and Mobil 1 5w-50 are PAO base oil

both the M1 0w-40 and M1 10w-60 are group 3/4 mix with the group 3 being the greatest, however, base oil is only a small part of the story as i'm sure you know, the additive packeage is more important.
 
M1 ESP 5w30 and M1 5w-50 are full PAO (not including the usual >3% mineral content to dilute the additives)

M1 0w-40 and M1 10w-60 are group 3/4 with there being more group 3 than 4

hope this helps

How many of were downright astonished to find out that Pennzoil Platinum was that great oil that it is?

.... and the list goes on and on and on.

Sometimes - the "recipe" in real world applications performs better than the sum of the parts (on paper).

Many of us are hung up on the idea that more PAO is better. That still may be true - but I am not as convinced as I once was.



Absolutely

PAO isn't actually an amazing lubricant, only when the right blend of additices are mixed with it does it perform well.

Additive package is just as, if not more important.

Research and learning

You can usually find out about base oils of a particular brand from msds's they always list them like ingredients in food, greatest first.

You have to really look on exxonmobil's msds's because they dont list it in the composition part but further on in the toxicology section

Wonder what they mean by this:

With the exception of Germany, this reformulation will be invisible to
consumers and B2B customers.
• Claims are identical with the exception of some now obsolete or soon to
be obsolete claims
• Performance of new formulations are equivalent to current formulations
Testing is underway to provide read-across of current marketing
claims to new formulations
Review will take place of current marketing literature to ensure
accuracy of specific claims to new formulations (e.g. if we quote
actual pour point values then this would need to be updated).
• There will be no proactive customer communication relating to this
reformulation. However, an internal briefing document and Q&A has
been prepared to allow sales to respond in the unlikely event of a
customer question.
Due to the unique definition of synthetic in Germany (Synthetic = 100%
PAO) this reformulation is visible to the consumer and B2B customers.
• A more proactive communication is being prepared for German use
 
It means they were making the switch and didn't want their customers to know it.
 
Well, it's really a no brainer if you can completely match the performance of a PAO at a much lower cost. The new Group III+ base oils are in par with PAO's. There has been an advancement and it works. PAO's may have the slightest advantage in certain areas, but the differences at this point are so small.
