Nobody has ever been able to answer that question.What's the point of using a 0W Oil in California?
Maybe for those minus 35C days.

What do you mean a "light" 40?What is meaningful is that it's a light 40 ..

How is that "lighter" than other 40s?
That's because it's a cheap consumer product with a high price tag. If a 0W40 is needed for cold starts, Delvac is the answer for HD applications. If 0W40 is not required why use it? Go with 5W40, 10W40, 15W40, 20W40 25W40 or SAE 40 instead.The downside to 0W-40 is there is a bunch of VI in it to make the spread work - and it tends to shear - because the OP is moving through so much oil he wont really be effected (nor do most anyway) by this.
My titan will shear it a full grade down in 7500 miles.

But likewise it doesn’t hurt anything either. If the oil you want has the approval or license you’re looking for and just happens to have a 0W winter rating then there is no reason not to use it.Well, when at operating temp, it's just a 40 grade after all and the 0W part doesn't have any meaning anymore.

0w40 oils are far from "cheap consumer products". That viscosity spread requires a very high quality base oil. Add on top of that the rigorous approvals that most of them carry, and your statement couldn't be further from the truth.
Pic posted!Lets see some pics, I love that era of GM HD trucks. You could run either weight with no consequences in your 6.0. Unrelated but I've run the 15w50 in my 2001 2500 with the 8.1 since that is well established as a simple fix for the oil consumption issue that engine has. I've had good results with Mobil's High Mileage 10w40 reducing consumption in a 5.3 Yukon. I've also had good results with Valvoline's High Mileage 10w40. Since you've been running Mobil so long, I'd try their 10w40 High Mileage.

The above product is very close to passing 10w40.
Ha! Yeah, I knew I was going to called out on this. (and rightfully so) I struggle with editing my comment all the time when posting on my phone. In this instance, I just rage quit and hit post rather than try to get rid of the reply box.MacManus99, user friendly did quite the rewrite on that.
(not sure how this ended up bolded? )
