I changed the oil today in the 2014 focus. Had 5200 miles on the oil. I was surprised the oil smelled of oil as bad as it did. I have certainly smeled worse but when my mom went to 12000 miles in her 09 focus on pyb it didn't even smell as bad as this did. I do mainly highway miles as well. Anyone else noticed this with di engine's. I know they are more prone to dilution but didn't think in 5000 miles it would smell so strong. Any thoughts?
