Everything I have read in the Diesel supplement on oil changes says to do the changes when the computer tells you too... which will be between 7500-10000 miles.
I have never been much for waiting until the computer tells me to do an oil change but rather just change it based on miles and figure it is cheap engine insurance on the other vehicles I have owned.

I am new to the diesel engines and wonder if they can go longer between oil changes since they have a much larger oil capacity ??

Do I need to do a "break-in" oil change at a certain mileage or just wait until the 7500 mile change ??

I know the huge can of worms that can be opend by asking this but.... what type of oil do you guys suggest ?? I usually run Mobil 1 synthetic in my other gas vehicles. Not looking to start an oil brand war but maybe just some suggestions and what NOT to use and stay away from.....

Sorry for the newbie questions but I really don't want to mess this up on my first new truck like this.

Thank you !

 

Go by what the manual tells you, for the first break-in oil change i would change it early though, if you want to change it every 5k instead of every 7500-10000 that means cheap insurance for your motor, like better lubrication and keeping sludge out.

Just make sure you use diesel oil, i run rotella t synthetic and have good experience with it.

 

For your first oil change I'd do it early, maybe 2k miles. I have always used Amsoil with great results. However it is pricey.

 

Thank you for the info.
I will change the oil early for the first time just to be on the same side.
I am not scared of paying alittle bit more for oil or filters. I already run over pirced oil filters on all my vehicles just for the convienence of having a 1" nut on the end for easy removal.

 

ok, got some more newbie type oil questions.... sorry in advance for the stupid questions.... looking for some guidance from people that know alot more than I do about this stuff.

I was going to use the Rotella T6 full synthetic oil because I can get it locally at Wal-Mart and I had resolved to using a 10W-30 oil in the new truck because it seems to be what is suggested in the manual.... BUT ..... the T6 full synthetic is a 5W-40 oil.
The Rotella synthetic blend T5 is available in the 10W-30.

Which to use ??

Thank you in advance for the advice !

 

Well I have the 6.4 so a little out of the ball park on the new motor, but I would advise that you don't go by the computer.

With the 6.4 going foward you need to be concerned about the emissions stuff and the effect on the motor.

I would advise a 5K interval myself.

Another piece of advice. Use motorcraft oil and fuel filters may specifically for the truck. On the 6.4 there are aftermarket ones out there but they have issues with not being able to seat properly.

So I know this is a completely different motor but these are the simple things that can amount to big issues.

I would never run extended intervals in these newer motors.

 

rotella 5w40 every 7500miles ,a new filtor(racor on dieselsite .com)and happy motoring.

 

for me, somebody considerably better than God would have to sign off on on using a wider viscosity over a long mileage interval. Viscosity additives wear out, and the wider the viscosity, the more of them. I'd stay with the 10-30 the manual recommends.

 

I am hoping that Motorcraft comes out with a 10W-30 in the Powerstroke blend just as they have the 15W-40 now. Thats what I am going to use if and when it comes out. If they dont come out with it then I will just stick to the 15W-40 Powerstroke oil they have out now! Motorcraft is ALL I use on any of my vehicles, even the ONE (The wife's Jetta) that's not a Ford!!

 

thanks for the info !

gonna have to check the dealership in person and see what they have to sell .... I called them..... the parts and service department are saying my truck takes two different oils... one is saying full synthetic the other is saying a blend. Both are claiming different weights.

 

Full synthetic for long life. Plus reduced chance of coking the turbo if you shut the engine down without a cool down.

 

FYI,

The technician mentioned today that it was advised that we stay away from Rotella in the new engines. Im sure why, just what I was told.

 

without looking at the manual, I know with the 08 and up 6.4 you have to run CJ4 oil for oil burners. So not sure about the 6.7, but that may be his thinking. Check your book.

 

Great example of why we should be careful about who we listen to- Read your owners manual
IMHO do the first change early at 2-3k with conventional and then 5-7.5k oil change intervals with synthetic thereafter (motorcraft, mobil1, rotella, etc).
Good luck

 

go with the oil that your book states, atleast until you get 25k miles on it. synthetic is not recommended so early in the engine break in period. amsoil is a great product, especially if you plan on running that 10k mark. maybe even look into a bypass system. i agree with the masses here and change it at 5k.
