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.

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.

Hmmmm what about 0W40? Fuel dilution concerns?

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.

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.

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.
