I noticed that the oil level was above the top hole of the dipstick and it smelled like an additive or gasoline was getting into the oil. So, I did an oil change at roughly 360 miles and installed 6 quarts of Mobile One. I used the FL910S Ford Oil Filter. The oil level was below the line of the hash mark not the dip stick when I was done. The vehicle now has 2833 miles on it and with 85 degree weather and a hot engine, the oil level was 1/8" above the top hole. After the engine cooled down, the oil level was at or below the top hole, but the garage was still warm around 83 degrees. I have been getting good fuel economy on a 1500 mile trip of 25 MPG and on a highway only trip of 27.5 MPG. The oil has some oder, but it is not as strong of a fuelish type oder as before at 360 miles. I previously had a Ford Fusion Hybrid and I did not have this experience, except that it's oil level would creep up 1/4 to 3/8 inch after 500 miles of driving - still only putting in the correct amount of oil. The reason I mention this is I am suspicious if the Start-Stop function is allowing too much fuel to pass with the start and stop if the engine. The dealer is good to me and I can certainly ask them questions and will get an honest answer, I just hate bugging them with my OCD type questions. Does anyone have this kind of experience with the oil level rising and dropping significantly with temperature? Is Ford putting in an additive in the oil at first that makes the oil smell like something else is in it? Has anyone had problems with fuel getting in the crankcase on their new Ranger ?
