OK, I have 1200 miles on the truck. I'm Planing on going camping next week up to Hilton head SC."about 400 mile's one way" I was thinking of pulling out the original oil and putting in 15w40 dino oil. Or shouldn't I worry about it and let it eat. Do you guys know, if the factory oil is 10w30? My Trailer is 10000 lb's

 

The truck will tell you when to change the oil.

 

Epic put up his first oil analysis and it said 10W30 was the oil. I don't know if Blackstone has that info from Ford or if they are able to determine the type of oil from their analysis.

I thought the manual said 15W40 was recommended only for BioDiesel? Maybe I'm remembering that wrong.

 

It does say that. And 5w40 for trailering. But the only 5w40 I can find is syn. And I think its to early for that.

 

I'm with you there on the synthetic.

It is also hard to find 10W30 CJ-4 non-synthetic.

 

If you're worried about putting a synthetic in the engine too early you may consider Rotella T6. It calls itself a 100% synthetic but it's really only a sorta-synthetic because it is comprised of a large portion of group III base. It doesn't take much to classify as severe duty and require a 5W-40 oil according to the owner's manual and it is a great weight considering the winter season is upon us.

 

Thanks, But someone forgot to tell mother nature it's winter here. Its 85 today.

 

One could also take the complete opposite position, you may want your first 5000 miles or more to be run on the original oil so that the internal engine parts actually DO wear a little bit.

I ran 5K on my original oil, most of it pulling our camper and also trailers for work. After that, I now just change it when the truck tells me to.

 

I wouldn't worry about changing the oil so soon. If you are concerned about the break in period, I would suggest changing just the filter and top the oil off with some Motorcraft 10w30. Lack of filter capacity is more of a problem on diesels than the ability for the oil to last longer. I only have 1750 miles on mine right now but somewhere between 2500 and 3000 I intend to change the filter itself. After that I will ride it out until the "smart" truck tells me it's time for an oil change.

 

I had the dealer change mine around 5,000.
I'm changing it around 10,000 next then from that point on, I'm letting the computer take over (maybe with a little input from me but we'll see).

 

I ran 4500 miles with my original oil and 2200 miles were towing 13000 pounds of fiver. The truck had 1200 miles when I hooked it up.

 

Will that not change the dynamics of when the computer can accurately tell you when it needs to be changed?
My biggest concern for that would be the oil dilution...if its adding fuel in the oil from regen and its close to telling you to change it and then you change the filter and set the oil level to its correct level...now the level is right but the dilution is all wrong....??? Is my thinking off??

 

The oil change indicator does not in any way analyze the oil itself. The computer calculates the approximate miles for an oil change interval based on driving style, idle time, number of regens, etc. If the computer has such a great handle on the actual oil quality, why do you have to manually reset it after an oil change?

 

Ok I gotcha..makes more sense.

 

We didn't analyze any factory-fill oil from ours, but we did and do change out the factory oil very soon (within 100 - 200 miles of delivery). Analyses on the following samples (~900 - 1000 miles on oil, ~1000 - 1200 on trucks) show that there's still elevated levels of wear metals and contaminants from break-in. We expect that, but those elevated metals levels are why we dump the factory-fill oil extremely early, and do 1 additional early change. From there, we'll drain the next time at ~10,000 miles so long as the previous analysis supports that interval.
