I have a 2008 chrysler 300 touring and the other say i changed the oil. Everything was fine that is until I took off the oil filter and noticed some oil mixture (oil and water). It wasn't a lot. I smelled it and it didnt smell like antifreeze. My antifreeze coolant wasn't low either nor did i find anything but oil on my dipstick. I was wondering if anyone else came across this problem and should i be worried. I use full synthetic oil.
