Hey guys haven't been on here in awhile. Picked up a crew cab '15 F350 6.7 in June and been busy driving her. Love the truck pulls great and definitely has a little more giddy up at the top end over my '11 6.7. 7k miles rolled around and time for an oil change. Threw the 5 gallon bucket under and drained the oil, when it was done it was only only 3" from the top, way more then the 3 gallon and a quart that it calls for. Measured it out and it came in right around 4 gallons of oil. Haven't been idling it at all and just normal driving back and forth to work. Going to contact my dealer in the am and see what they have to say. I saved 3 samples, one to send to blackstone, one for ford and one for me to keep. I'll keep you guys posted on what they say. Has anyone else experienced this? Never had this trouble with my '11. On another note anyone have any trouble with there tranny in tow/haul mode say 6th gear between 1200 to 1500 rpm? The truck shakes really bad, I'm thinking torque converter but I'm gonna have them look at it too

 

Who knows what issues could have come from 16 quarts of oil. I wonder if the shaking is due to the overfill?
Ford says 7% is the max allowed fuel dilution in the 6.7L. If we add that to 13 quarts that's still only 13.91 quarts of fluids in there.

How is the level in both of the cooling systems?

 

I was going to say that too. Who did the oil change? If the dealer, it is not uncommon for their guys to fill it like they did the 6.0L, which was 15Qts.

 

The shaking could have been due to that but its very specific to that gear and rpm range and only in tow/haul mode. I did the oil change, I measure out the amount I need with a gallon can and quart jar so I know I didn't over fill and I didn't add any in between oil changes (first one was at 2k miles) I know more once I get the oil report back from blackstone. As I sit here and think about it I haven't been noticing as many regen messages lately ether.

 

When I changed the oil in my 6.0 it was always within 3" from the top of a 5 gallon bucket. Thats my guess too.

 

Interesting. As many of us move into these new trucks we will need to watch this closely.

 

Well, that wasnt the answer I was hoping to hear for your sake. Good call on the blackstone analysis.

Are your coolant reservoirs all up at normal levels?

Please let us know the results of the test.

 

Send me your info in a PM, emd160; I'll escalate this up to your regional customer service manager so they can assist. In your message, please include your full name, best daytime phone number, VIN, current mileage, and servicing dealership.

Yep coolant levels are good. If there's a good side to this, its that I can usually make it do so hopefully it wont take long for them to find the problem and fix it. Thanks Crystal I'll get all that info sent over to you by days end.

 

Sounds good, emd160; I'll keep an eye on my inbox for your message.

Not a direct comparison but my 08 "made" oil every change. It got to the point that I installed a fumoto valve and drained down to 1 quart low and added a quart of fresh every 1000 miles between changes.

The very interesting thing was that many other owners reported oil "growth" but many said they did not experience it. I was never able to figure out why some did and some didn't. The dealers just scratched their watches and wound their azzes and said to use the short stick method to check it. I finally put a stop to it by deleting and tuning the truck. Hope you find a better answer than I did.

 

I too have heard of some people having problems with making oil and there solution was to delete too. From what I understand it has to do with regen. If it would have been half a quart or even a quart I wouldn't be to concerned but 3 quarts is an extreme amount and unacceptable to me on a brand new truck. It tells me something ain't right. the service manager said to change they had no way to test it and to change my oil sooner. I'm waiting to see what the black stone report says. It goes in next Thursday for the tranny. On a plus note a big thumbs up to crystal and ford customer service, I gave her my info last night and first thing this morning the regional service manager had already called me about my truck.

 

I'm browsing the 6.7 forum for the first time; I have a 6.0. Do you help out on the 6.0 forum also?

 

I'm not advocating that you delete and tune. I, more than most know the down sides of that decision. You can call up my many posts on the subject for some fun reading. But it will solve the problem. During regen the computer signals a load of diesel to be injected in to the cylinders to cause the burn off of accumlated soot in the DPF. In some trucks a lot of diesel gets by the pistons and into the oil. That results in "oil growth". I would suggest you look up that phrase and some similar phrases and read up on the potential problems that can result. It can be very serious. If there isn't anything here try the 6.4L forum, it was a pretty common problem there. If you live in one of the corn states where B20 is mandatory that will also contribute to your problem. You can read the EPA report on " The impact of bio diesel on DPF equipped vehicles". It's under my signature back around 2011 or so. The bottom line is that "diesel" will burn out of the oil when it gets good and hot there by reducing the level growth but bio diesel will not or at least will not do it as well as diesel. The interesting thing is that the 6.7L is rated for B20, the 6.4L was not.Only to B5. You can also find some emails I exchanged with the US bio diesel board back around 2012. They quit responding after I asked some hard questions.

Finally, I would suggest that what you will get from Blackstone is a report of oil high in dilution by diesel. I got those for three years. The highest was 6%. When i dileted I changed oil and filter and 5000 miles later I got a great report. The difference was so pronunced that the testor commented that this was the first perfect report for my truck.

I can also tell you that when I was doing the mini oil changes at 1000 mile increments my reports improved a good bit. I think I could have kept doing that and the engine would have been fine but it is a bit of a PITA. Since you do your own changes as I do you could probably handle it. I had it down to a 10 minute chore by the end. The hard part was reading the dip stick on the 6.4L.

Hope some of this helps you. It is frustrating to pay what these trucks cost and find out that the political driven technology is crappy. But making that sized investment I want to maintain it as well as I can. I'm sure you do too. Good luck.

 

Hi mattdoc88,

For the most part, I can only assist with newer-model concerns. For a better idea of the kinds of things I can help with, I recommend checking out our intro thread here: https://www.ford-trucks.com/forums/1...rting-fte.html
