Hello All,

Long time lurker, first time poster. I think I may have read every single thread on TGMO since 2012 in it's SM formulation and as it has progressed through SN, and the speculation that it is using trinuclear moly etc etc. very spirited debates on this board, which I have enjoyed reading. However where some people have called debates "academic" at the point where an oil goes below -20C and below is a fact of life where I live ( and love every minute of it). I live in Edmonton, AB. We are avid skiiers and winter hikers. To be quite honest, when everyone battens down the hatches at -20 and below, we get in the RAV4 and go. The RAV has a block heater, winter tires, -44C coolant and a wired-in 4AMP battery tender, to keep the battery at 100% even during cold temps. It has started in -32 with minor hesitation on TGMO 0W20 SN (when I forgot to plug in).

There have definitely been occasions where I have been out at -20C and below and the RAV has had to sit unplugged for 5-8 hours at a time while we hike. Now, while most people would think this is crazy, this past winter I got so hot, I did the hike with my jacket wide open. Born in the north I suppose.

Now to the obvious question I have come here to answer..without the use of a block heater, How much am I gaining by going to M1 EP vs TGMO 0W20? while these trips are interesting since many a time there is no reception so getting back to my vehicle is my life line, they still are only about 50-60% of my overall mileage. The rest are generally short trips in the city. 10KM (6 Miles) and under though in this case, its kept in a heated garage, so starting temp is pretty much moot. Where I am , I can get TGMO 0W20 for about 32 for a 5L jug, whereas M1 EP is 60 for a 4.4L jug. Which would you pick and why? is there much to be gained from M1 EP? Thanks for your thoughts!
 
I am not an expert, but I strongly suspect you will be fine with any brand-name 0w20. I start my car at -20 all the time in Jan/Feb without a block heater (I do not have one), and I find 5w30 PP works very well for that.
 
Cool! Thanks, Yeah I assume your right especially since I grew up here in the days on 10w30 conventional, and we got by just fine. I suppose the question is simply one of "protection" and fringe temp cold temp starts where it does hit -30 . I just got the vehicle since my last one was written off. The last vehicle had lifetime oil, so i gave it no thought but I was allowed to choose grade and did use 0W20. I'd like to pick an oil and stick with it. TGMO being almost half the cost appears to be the clear winner for me right now. but if there is truly an advantage to M1 EP on the bottom end of the temp range, say at -30 and im not "losing" anything else. it may be worth it as well. I do agree with you though, that most any 0W-20 should work. I know with my older 2007 Honda Accord once it hit -32 i could not start with a 5W-20 but with a 0W I could, I was stuck at work multiple times because of this ( No plug ins available). This caused me to switch to 0W years ago (Prob about 7-8 years ago when 0W was "new") and I have used nothing else but that since that time and have had no issues.
 
Any and every 0W oil has to meet a cold weather performance spec. My old BMW with 0W-40 regularly starts outside in northern Wisconsin where it occasionally gets to -35 Fahrenheit or below.

Any car with 0W- oil that does not start at very low temperatures isn't due to the oil. There is a lot that has to come together to start at those temperatures. Everything has to be in good working order.
 
Yeah any 0w should do well. Block heater is key when you can plug it in and a strong battery. Cant do more than that unless you look at a battery blanket or something.
 
A solar panel would keep the battery topped off and warm(er). It would have all the effect of a tea-light candle left under the oil pan.

both are fine. Would comment that if emergency prep is your goal, then pack a sterno or other small heat source that if worst comes to worst you can place under the car to warm it up.

I'm sure if you want to do it right you can Google and find preppers who will give you a more optimal list of emergency gear you should keep in your car

So 0W are pumpable at freezing temps, I understand that. But for the OP, wouldn't the weight count too? A 0W40 would surely be thicker (whilst still pumpable) than a 0W20.

I plugged in some data on a viscosity calculator spreadsheet I downloaded from here.

A 25W70 has 900 or so cSt @ 25C
A 0W16 has around 1300 cSt @ -20C

Would this not mean that a 25W70 is more easily pumpable or flows quicker through the same engine @ +25C than it is with a 0W16 @ -20C?

In any case, should the OP not use the thinnest possible oil in -20C weather as it's still going to be [censored] thick at that temp?
 
raytseng that is a great suggestion thank you for mentioning it, I actually do have a jetboil backpacking stove that would actually work for that purpose in an emergency! Great, great point!

Unfortunately, finding hard data online for TGMO or M1 EP 0W20 is beyond me.
I do see that the PQIA looked at M1 0W20 early in 2016 and reported a -35C CCS viscosity of 3928 cP, compared to a maximum for its grade of 6200 cP.
I'd say that being 37% below the max allowed suggests very good extreme cold starting ability, but I can't find a TGMO value to compare this to.
In the 5W30 grade, M1 EP is slightly thinner than M1 in the -30C CCS test, but who knows if the same holds true for the 0W20 versions.

lifetime engine oil eh?

what make vehicle was this?
 
I think you must be referring to Mobil 1 AFE 0W20 as the only Mobil 1 extended performance 20 grade we get in Canada (or at least in Regina) is 5W20.

I use Mobil 1 AFE 0W20 in my wife's 2016 Rav4 all year round. There is absolutely no reason to pay $60 per jug unless you need it now. I buy Mobil 1 at Canadian Tire for approximately $33 per 4.4 litre jug when it goes on sale. If you watch, Canadian Tire has a different oil on sale every week, and Mobil 1 is in the rotation every four weeks or so.

If you decide against going with TGMO as I have, another cost-effective option is Pennzoil Ultra Platinum 0W20 which also goes on sale at Canadian Tire every four weeks or so for approximately $33 for a 5 litre jug. Pennzoil has a rebate program (google Pennzoil rebate Canada) worth $10 per jug of Ultra Platinum. That brings the price down to $23 or so. There is not a better deal available in Canada.

Good luck.

M1 AFE 0w20 has the lowest MRV of commonly available oils in the US.
Maybe PetroCanada has some really good low temperature oils.
 
Uregina09 - We do seem to get Mobil1 0W-20 Extended in Canada see here - http://www.canadiantire.ca/en/pdp/mobil-...89929p.html#srp Though im not entirely sure what the difference would be between EP and AFE.

Also, for those wondering when I said "lifetime Oil" - I meant lifetime oil changes included at the dealer since I purchases my last vehicle new, not a magic potion that makes my oil last forever

Anyone have any Idea on the MRV @ -40 of M1 EP 0W20 vs M1 AFE 0W20? for some reason Mobil does not list it.
 
I'm happy to be shown that we have Mobil 1 EP 0W20 in Canada. I'm thinking that the MRV value differences between it and AFE 0W20 will be splitting hairs and academic in the real world.

The M1 Extended Performance line is advertised for up to 15k mile OCIs. AFE is not advertised as an "extended drain oil" by Mobil.
