Ok, so my 2nd oil change was done at 6000 miles. (4k) Then, I read on other Ranger websites, of some owners dealing with a "increase", in oil level following their oil/filter change, possibly due to fuel getting into the crankcase. I wasn't careful when setting/adding the oil to my engine, just dumped in the 6 quarts, ran it checking for leakage, pulled the stick, verified in-between the marks, and motored on--since reading about this issue, (mileage now at 7000), I checked the level after sitting o/nite--level is 1/4" over full mark. Will continue to monitor, but I'm wondering if the "design" of the high pressure pump, allows a small amount of fuel, over time, to enter the engine/work past the pump interior, just as a characteristic?? My fuel mileage is great, and have no driveability issues, but this alone would be cause to change oil at 3k intervals. Anyone else watching this closely??
