DPF delete/EGR "off" & Spartan
tuner at 600 miles
Never raced or abused
I just changed the oil in my truck after 3,500 miles, with approximately 650 miles towing my bass boat and 600 miles towing my 8,000# fifth wheel.
I've never let anyone else change my oil in the past 40 years, so unless I'm getting old and forgetful, I'm pretty sure that I put 15 quarts of Shell Rotella 15w40 at the last oil change.
Anyway, I always check to see how much oil I drain and this time I was shocked that it was only 12 1/2 Quarts!
The motor isn't leaking any oil and it is impossible to tell if I'm getting any out the tail pipe since there is a lot of soot from not having the DPF.
This is my 5th Ford 6.4 and the first time I have ever experienced any oil consumption in between my scheduled oil changes (3,000 to 4,000 miles). I did have the "extra oil / fuel in oil" problem on my first 6.4, but solved that problem with turning off the EGR.
Any Ideas where my Oil is going?!?!?!?!
