I have a 95 Escort 1.9L that I use for work. I notice when I check the oil I always have this pasty substance on the dip stick along with under my oil cap. I run 5w20 full synthetic high milage Valvoline oil. For the last 6 months the temperature has been mostly below freezing. My coolant seems to always be full as I've never had to add any and my oil level remains the same at all times. Wondering if it's just from the cold or possibly another problem. The car runs smooth doesn't knock or make any weird noises.
