I am not sure if it is going to get cold again around here this year but if it does I will do this again at a lower temperature.

Here are Rotella T 15W40 and Rotella T6 5W40 (Syn) at -21C.

T6 on the left in the video.

Thanks

 

Just a heads up for the Canadians on here, Canadian Tire has the Rotella Synthetic on sale 25% off this week.

 

That is why I use T6 in the winter.
I buy the gallon jugs and do my own oil changes in the winter vs paying the extra that oil change places want for full synthetic.

 

What should I be observing here?
Also, did I see another video like this on here that Epic did?

 

I run synthetic in all my equipment all year round for the heat and cold. You can definitely hear the difference in my tractors when I start them when it is very cold out. It also made a big difference in my last truck a '05 6.0L. I don't plan on running non-synthetic in my 6.7 so won't be able to compare those the difference.

 

Molasses on the right........

I have T6 in the garage to put in her shortly. Good post D

 

Thanks a lot, 15 l of T6 cost me $500.00!
Always find a few things I can't live without

Good heads up, I rarely ever see it on sale

 

Funny how simple and revealing that little video is Darren. Thanks. It shows how well the synthetic flows at low temps. That's one of it's biggest advantages. What the vid doesn't show is how well it holds up at high temps. Dino oil begins to break down at 240 degrees, full synthetics at 400 degrees.

 

That was quite telling as six below is not really that cold. Further, I though the syn would have performed better.

 

Thanks for that, also keep in mind that Canadian Tire has higher regular prices most days and then drops them down to a more normal price for a sale so their sale prices seem to be a high percentage off the regular price (this is a thing they do store-wide, not just oil). In this example, the Can Tire regular price is $43 while other places such as Peavey Mart have it for $36 regular price. Haven't checked UFA yet.



Hmmmm what about 0W40? Fuel dilution concerns?

 

Yeah I saw that when I went in to get it. Its $35 or $36 at Peavy and Walmart regular price, so $32 isn't a steal at all, but 15L for under $100 all in is still pretty good.

 

As far as temperature range goes, this is basically how it was explained to me by the company we buy oil from (we purchase by the drum for our business):

0W40 for when you never see temperatures above 0*F (think Arctic conditions)
5w40 is great for typical winter use down to around -15*F or so
15w40 you don't want to use below 10*F if you can help it.

I always followed that with my diesels and never had a problem with them starting in the winter, whether it was 25*F out or -25*F out, regardless of them being plugged in or not.

 

Nice educational video.
This shows where the extra cost of synthetic is helpful (cold temps).
Down here, I'm happy with the less costly motorcraft 15w-40 for now.
Who knows, I may switch over one day for the heck of it.
It is said we're headed into a mini-ice age.

 

Can someone explain this a little better for me that is knowledgable? I 0w-40 , 5w-40 and 15w-40 are all the same "performance" when the motor is up to temperature all being 40 viscosity what is the down fall of using a 0w oil compared to a 15w oil? I wouldn't think it would be bad to use a 0w oil even if you only drove in say 20 degree weather at the coldest because it shouldn't hurt anything as opposed to using the 15w oil which would be more "suited" as people say here if you do drive in weather of 20 degrees? Little help here. Is the lower weight oil more expensive or something? Just trying to learn a little here.

 

With modern oils there's more to oil than just the weight. There are also additives for reducing wear, negating the effects of fuel dilution, reducing acidity, ect. Different formulations accomplish different things. It's always best to use the right oil for the situation, even if it's still an acceptable weight.

I know from seeing multiple oil analyses that 0w40 tends to break down faster than, say 5w40. Depending on what your vehicle is subjected to and when you change your oil, that may not be a big deal. For fleets (or individuals) trying to maximize their oil change intervals for cost savings, it can be problematic.
