Winter oil?

[MyFirstDiesel]

Do you guys run a "winter oil" in your trucks? I run motorcraft 15w-40 in my truck right now and I really don't want to switch for the winter but if you guys think it's a good idea I will do so. If so, any suggestions? Also, why would I run a different oil in the winter? Is there a certain temp to run different oil?

What's your location? That'll make a difference.

Location?
I dont but the coldest it gets here is 25F or so. I go to colder places but I plug the truck in so I am not too worried about it.

NE ohio.

It'll get in the single digits occasionally here with wind chill.

 

[MyFirstDiesel]

Or should I just continue plugging it in and if I notice it starting different to change the oil to 5w or something?

 

[MyFirstDiesel]

Mind you guys that the truck is kept in the pole barn and I can heat the place up during the day and plug the truck in at night if I needed to go to that

Cost doesn't really matter I just want the best I can put in this truck. Seems like most guys are running Rotella syn. 5w40 in the winter if not all year round

I just switched from Rotella 15w-40 to Mobil 1 Turbo Diesel 5w-40. I am a little further south than you. It may be a mind game but it seems my truck drives a little different in a better way

If you go to 5w-40, which would be fine year around, I would use the valvoline extreme blue full synthetic.

What town do you live in?

If I can find motorcraft 5w-40 syn. I'll get that. If not I will probably use Rotella 5w-40 synthetic. Thanks for the info. And I live in Canal Fulton. Between canton and Akron.

Also is it okay to go from motorcraft 15w40 to the Rotella t6 5w40 syn?

It will be OK.

If cost isn't an issue, why not run the best oil year round? My old dinosaurs start every winter in the negative digits without being plugged in with good ole delo 15-40... can't see a 6.4 having issues like a heui motor would...

load it like a box car, drive it like a stock car..

So the best oil for these things is 5w-40? Even through 15w-40 is recommended?

Myself, and our company run full synthetic 5w40 year round.

Guess I thought that a 6.4 was supposed to have 5-40 syn in it?

Run rotella 5w-40 synthetic year round here

I use Valvoline 5W/40 extreme blue full synthetic all year, never any issues.
