Genrral Question and an issue... 2011 6.7

[MG278]

Hello all,

I have a 2011 F350 6.7 (11/2010 build) I was wondering if anyone has added militec 1 lubricant to the crank case? I have some surplus and was curious of anyone has added and what the results were if any.

My issue has been that my water in fuel message seems to be coming on a lot and especially when the weather is wet (rain and snow).

I fuel up at the same location every time and use Hess diesel.

I have changed the fuel filters two oil changes ago my truck has 19500 miles on it.

I run a fuel additive every fill up, either POWER SERVICE or STANADYNE.

Anyone else having this issue??


Thank you

If you are getting WNF and always use same fuel station ... ... Why wouldn't you just switch fuel stations?

I've got 12k on 2012 and have never gotten MSG. I've drained the catch twice and always pure ULSD. Never any H2O.

With over 70,000 miles on my truck, I've never gotten that message, I agree with the above. Maybe its time to change where you buy fuel and see if the messages go away.

Have no comment of the Milspec oil. I suspect that if it is marked CJ-4 then it should meet your engines specs and be OK. One of the main improvements in the CJ-4 rating was the removal of phosphorus and sulfers to meet the 2007 emission standards. If the Milspec oil was not designed to meet that standard, then you probably would be seeing more Regens and increased emission coming from your exhaust.

have you drained your water separator and gotten water out?

Yes I drain it everytime the message comes on and once a month. I will try to switch up fuel stations see if that helps.
