Fuel in Oil

So my father bought an '11 cummins not to long ago, and its got about 2500 miles or so on it. He checked his oil and found it to be awfully high, come to find out theres fuel getting in his oil. Anybody heard of this problem before and could shed some light on it?

Well hes only put about 2500 to 3000 on and he replaced the oil last weekend and this weekend its already a quart high he said. He wants to delete his emissions anyway, and has a dpf delete pipe just isnt sure what programmer he wants. So if he pulls his dpf would it clear up the problem?

Excessive EGTs to get the DPF hot enough to clean like a self cleaning oven. Larger trucks and the 2011+ Dmax engines have an extra injector in the exhaust to trigger it but the 07-10 trucks and 6.7 Cummins engines all rely on excessive amounts of fuel and other means (like a throttle in the intake) to increase EGTs to clean the DPF.

Yeah only a politician would think that makes sense....
Yeah they all did it from 07.5-10, Chevy got the bright idea to move an injector and what is basically a sparkplug into the exhaust to burn up the DPF remotely. I am unsure if the Ford still uses an engine based regen, I know for sure the dodge does.
The dealer might reflash the ECM so it uses more throttle (make the engine run richer) instead of dumping more fuel. But the newer trucks like to make oil...not uncommon to see fuel percentages above 5%.
You want to see more nasty stuff...look at your EGR...
Supposedly this engine only had 600 miles on it..if that is true...YIKES!
