I just purchased some Mobil-1 0W-40 on sale the other day at CDN Tire and noticed a few changes with the labels/info.

Namely, and the reason for this post, was it's advertised pour point of only -40?

I have a left over bottle from last year and I noticed the advertised pour point was -54, why the change?

The older stock has API SM,SL/CF and the newer bottle has ACEA A3/B3, A3/B4 API SM,SL.
I would assume the formula has changed some but I don't understand the higher point point? Is the oil just as good as it's always been or has it been cheapened somewhat?

Sorry if this has already been discussed?

M1 0W-40 is not API SN? I thought that meant a lot.

The latest PDS on Imperial Oil's site no longer lists the pour point, and it did list the -54 C pour point before, as you mentioned. I would guess that, assuming this pour point increase is correct, this reflects a reduction of PAO in the base stock. Incidentally, the pour point for M1 5w-30 is listed as -42 C on the site.

So, perhaps it's "cheapened" but it it still bears all the relevant approvals and specifications.

I was always under the impression that an SN oil was better (than other oils) so I am liking this 0W-40 as a quality oil (for those that need a 40.)

It's probably using Visom, with PAO/V base oils. I notice they use the words "Ultra High Peformance Synthetic Basetocks" for this grade. Most oils use multiple basestocks.

Hopefully not but I will have to check out some recent UOA's to see if any noticable change was noted?
I do only use this oil in my Yamaha Vector snowmobile and I certainly don't plan on sledding in -40, but it has happened!

The -54 just gave me better piece of mind knowing that it is protected to that temp and knowing I would probably never get to that temp but now with only the -40, I do have some concerns?

Might be time to check out some other oils that exceed that -40 limit just to be on the safe side?
Any other options out there?

Thanks everyone! confused

What really matters is the MRV figure at -40C. Does anyone remember what it was for M1 0w-40 in the past?

Not getting your point? What is MRV and what difference(s) does it matter with the temp at -40 or -54?

MRV tells you how thick the oil is at a given temperature (-40C in this case). The lower the value, the better the flow at that temp. So I was wondering how this value changed from old to new formulation.

Did anyone notice neither of these bottles are SN???

Now to clarify, I'm not saying the NEWEST M1 0W-40 isn't SN, just that these "sale" priced bottles are not... May be why it was on sale???

FYI, if you're really concerned about cold/startup flow at such low temps, you'd be better off using M1 AFE 0w-30 and not M1 0w-40. MRV for M1 AFE 0w-30 is much better.

Thanks, and I believe you are right as far as the AFE oil goes.

When I first bought this sled and was wondering what oil to use, (other than the crazy expensive cheap Yamalube oil), the AFE 0W-30 oil was not available so that is why I chose the 0W-40, and due to the fact it had a higher ZDDP content.
http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1868692#Post1868692
Now that I see I can readily purchase it, I think that is now the oil I am going to use from here on in?
Just wish I didn't purchase 6 bottles of the 0W-40!!! mad

If in a garage, then you're probably not starting it at -40C, even if it's -40C outside. I'm guessing the temp in the garage is higher than that. So you don't really need to be concerned about cold oil flow at that temp.

That's all very well but it doesn't do me much good when I go away riding for a week-end or longer.

Like what was written above, I think I am going to go with the 0W-30 AFE when I run out of this stock, or sooner if we have a cold winter ahead of us?

Got it. I would look for a 0w-30 oil with the lowest MRV then. M1 AFE is probably one of the best there, but there may be others.

Yes the Cdn version of M1 0W-40 has been up-dated to SN. See the Cdn PDS below:

http://www.imperialoil.ca/Canada-English/Files/Products_Lubes/Mobil_1_0w40.pdf

M1 0W-40 is not an especially great extreme cold performer, not with a MRV @-40 of 35,000cP.
A better cold performer at all temp's is the Mobil Delvac Elite 222 0W-30 (nee XD-3 0W-30). It's a true PAO based synthetic with a MRV of only 14,900cP. That's better than most 0W-20s.
It's a heavy 30wt oil at operating temp's with it's HTHSV >3.5cP.

Something to consider.

It does matter. Pour point is just what it is. I use it mainly to help determine base stocks, and even then, it's far from an exact science. M1's 0w-40's MRV is posted by CATERHAM, and, as he notes, is measured at -40.

You'll never get %'s but the 0w40 is most likely Visom, with other base oils. In fact, it was the subject oil in the Mobil PDF that was posted here awhile back that had to do with their switch to Group III+. I still think it's the best 40 grade on the market, including boutiques.

I agree in the States M1 0W-40 is hard to beat.
But in Canada Mobil has other great oils like the Delvac Elite 222 0W-30 and Delvac 1 ESP 0W-40. These are 100% PAO based with ultra low MRV's to show for it. The Delvac 1 ESP is a heavier oil than M1 0W-40 with an estimated HTHSV of 4.0cP but still has a much lower MRV of only 21,300cP.

If these two Mobil oils were available in the States they'd be a major hit on BITOG.

Yep and they've been available for years.
Used to be sold under the ESSO XD-3 banner before Mobil had them rebranded.
Here are the spec's:

No problem at an Imperial Oil distributor. CATERHAM likes the Delvac 1 ESP 0w-40. I prefer the Delvac 1 ESP 5w-40, at least for the higher TBN. I bought some a few years back for the old Audi. I don't recall what I spent on it, of course.

I was using because I seen the -54 pour point and figured it woulld be a great cold weather performer(other reasons as well)
I am curious about the -40 rating now so I wrote Mobil yesterday so we'll see what they have to say about the new rating and it's use in my 4 stroke snowmobile?
Thanks for the info guys, I appreciate it.

What grade and specifications are required for your snowmobile? There certainly are lots of choices out there, and we could help narrow it down if we knew exactly what it called for. For my snowmobile, I'm stuck in 2 stroke land. wink

I'm not sure about that M1 -40 C pour point, to be honest. We'll certainly need someone with more technical knowledge to chime in, but I find it odd that it has a pour point of -40 C yet an MRV test done at that same temperature. Then again, I think the Mobil Super conventional line has a pour point of -33 C, and MRV for the 5w-XX grades is measured at -35 C.

Good call. If it does in fact call for JASO MA due to having a shared sump, then I take back my earlier M1 0w-30 AFE recommendation. You don't want an oil with a lot of friction modifiers in such an application.

The OP should have posted this thread in a different subforum as many of us forget that this is not a regular PCMO application.

It does seem to have changed. Low temp performance seems to have taken a hit.

In Germany and AFAIK the US and Canada it was a full synthetic oil now its a blend.

The thing is, this change from all PAO to part VISOM formulation has taken place years ago, maybe 4 years or so (API SM)? It's strange that Canada is getting this changed formulation only now.

Thanks for showing me the specs he requires.

Anyhow, looking through my spec sheets, here's what I find for SG or higher and JASO MA:

Petro-Canada Duron-E Synthetic 10w-40, Duron-E XL 15w-40, Duron-E 15w-40, Duron-E 10w-30 (suitable for use for JASO MA, MA2).

Petro-Canada Duron Synthetic 0w-30 (CH-4/SM) is listed as suitable for use for JASO MA as well, and that's the correct viscosity.

Neither the Rotella 0w-30 or the Delvac Elite 222 0w-30 show any JASO approvals on the PDS. There is almost certainly a PC distributor in the Oshawa area who would be able to help him out.

@Quattro Pete: You shouldn't be surprised. We barely got SN/GF-5 Mobil 1 a year ago. wink

It happened last year in Germany. In Sept there was still old and new on the same shelf with the same price.
It seems to still be good stuff though unless you really need that extreme cold performance.

Cam wear numbers are a little better but main bearing wear is a little worse, all in all its a wash.

Friction modifiers, although it says so, ar not an issue with these sleds.
It has been proven time ant time again, they will not hurt these snowmobiles.
It was originally suggessted for Yamaha Atv's as they have a wet clutch, but these snowmobiles do not.

Anyways, this is my reply from Mobil today.
I am confused why the bottle states -40 yet in his letter it states -45?
I'm confused!


"The pour point is a static test and it can vary from formulation to
formulation, pouring of the motor oil is not important unless you just
want to be outside in -50F weather and watch the oil pour out of the
bottle onto the ground.

The cranking and pumping is whats important and the product still
delivers below -45F so your application can start.

Do you understand the difference between pour point and MRV?

Also, he's talking Fahrenheit, and the MRV spec is given in Celsius. -45F is approximately -40C.

Actually, -40C is exactly -40F.

You're right. -45F = -42.8C. Close enough. smile

Any where that has the potential to reach -50F, is no doubt a great place to be FROM...

If I had of know that I most certainly wouldn't have purchased it!
Might consider another oil like the 0W-30 AFE or actually reconsider Amsoil 4 stroke oil?

I agree with ExxonMobil that pour point is not an important or very informative spec. So why do they (and other oil companies) even bother publishing it? The MRV and CCS specs are more informative.

I don't know either.
In fact PP as the OP has learned is a very misleading spec' best ignored and that's the reason the CCS and MRV spec's were developed.

That is all very well but what are 99% of the population suppose to believe?

Like I stated earlier, I seen the -40 after the fact, and it's nobody's fault but mine I didn't look at the rating in store but I bet most don't, especially if they are purchasing an oil they have for quite some time.


So all this aside, what are your thoughts on it's pour point? Like I also stated earlier, I will be running this oil in my sled and with what the Mobil dude said, is it still a good choice?
Any recent UOA's with this new blend, and has it been proven that it is no longer as synthetic as it once was? Has it been cheapened?
Thanks

I'd go with Mobil Delvac Elite 222 0W-30.
It can be had from the closest Imperial Oil depot to you.

I do, both SM and SL.
Both give the PP at -54C.
