hello i will be going home on post deployment leave i bought a new truck and it is at home now in wisconsin. it is a 2005 6.0 powerstroke. 4x4. i will be driving the truck in the cold weather for about 2 weeks then taking it across country to california. back to where i am stationed at. i am just wanting recomendations to should i change the oil as soon as i get home in the first couple of days? or righ before i take the road trip.? also if you do recomend me changin it what weight and brand and type should you recomend me changin into it? it has 95000 miles on it and do not knwo what oil or filter are on it now. also any other sugestions before taking my truck across country? is it safe to take out the egr valve and spray it with break cleaner and make it all clean and shinny to make sure it doesnt get messed up on the drive.
thank you:ford:

or you can use the dino oil its 15-40.
I like valoine 15-40 i would use that brand now but they dont stock it in systeic

ok so a ford oil filter for sure. and a sythetic but should there be a specific weight i should sue wile in cold then traveling to hot? and running for 2300 miles. i will change it again once i get to cali. so prefeably an oil weight that will be good in that cold temps and be good for the drive cross country.
thanks for the info

I made many runs from Toronto to Laredo, in the dead of winter. All the trucks used Rotella T 15W40. You shouldn't have a bit of a problem running that in any foreseeable temps between Wisconsin and Cali. Now if you were going the other way to the Arctic Circle, I'd be looking at a different oil.;)

hey thank you for that info. so ill use 15w40 valvoline blue extrame. seems to be a good choice or rotella. just wondering the whole numbers still cofuse me with thickness and what not. is 5w40 better for cold? thinner? maybe i need a short class on number and thickness. whould running 5w40 for when im in the single digets adn below for cold starts be ok then taking it on the trip? sorry it probably sounds like im repeating my questions i just wana make sure im helping her start best she can in the cold but still giver her what she needs on the drive down. any other info ull think i might want for the drive down? fuel aditive? custom sct tune? for the long drive?

A lot of guys on here are using 5W40, and say the truck starts easier. It likely does, since your injectors are operated by oil pressure. I'll let one of the other guys answer your questions for the most part, I just don't know how to explain it.
The fuel additive may not be a bad idea until you get into warmer weather, I use Power Service in the white bottle, there are others out there, I've read where Schaefers is a good one as well.
Hopefully someone else will chime in, but you could do a search for fuel additives. A member called White Buffalo did a very good write up on the additives, it's worth a read.
Thanks for what you do, Semper Fi!!;)

At 7* not plugged in your injector will prefer the flow properties of 5w-40 over a 15w-40. 5 bottom weight oils have a lower pour point and will flow to the injectors better and prevent start up wear better (in theory) vs. a 15w-40. However, 6.0 are brutal on oil and maybe a 10w-30 might be a nice compromise for you. 6.0 can easily shear a 40 down to a 30 weight in no time but they seem to stop there.

I am not a 6.0logist but I would be confident with either a 5W-40 or a 10W-30 (like rotella T5), at 7* your truck won't like to start with a thick 15 weight oil in it, it will but it won't really enjoy it. On the older 7.3 under 50-60* ford used to recommend a 10w-30, 5w40s were not popular or easily found at the time.

And one other thing, a lot of people think a 5W-40 is thinner or lighter than a 15w-40. That is only true at start up, at operating temperature they behave most the same, a 5w40 will shear a little faster but not too much.
