TO MUCH DIESEL FUEL IN THE OIL

[henry]

I have a 2012 f-250 6.7 with 5,700 Mi on the clock and I have been taking oil samples. I just received my latest results with 2,500 Mi on the sample and it shows that my oil has 10.0% fuel dilution. The lab condemns oil at 5.0% fuel dilution.

My question to you guys is are you having this same dilution issue and if so what are you doing. I can't afford to change my oil every 2,500Mi.

Holy ****, that can't be good for the internals. Any codes? Do you idle excessively?

No No And no

My wife drives the truck to work and seldom gets over 25mph and travels about 15 miles round trip.

I would have the dealer look at it. That much fuel in the oil is going to change the lubricousity of the oil and shorten the life of your gaskets and seals.

So that's only 7 miles each way under 25 mph? I think we may have found your culprit.

It's like idling to work

I made my Samsung SGH-I997 send this.

Ya! I think you might be right. Going to start looking for a beater for the wife to drive. Thanks

For grins, take the truck on "long" drives only for the next 4-5k miles (highway speeds, drives longer than 15 min, etc). Work the motor a bit, and send in another sample. I'm curious.
