for the past week or so i thought i smelt burning oil but my buddy n my girlfriend said their was no smoke coming from my exhaust so today my dad was following behind me and when we got to the light he said he smelled buring oil coming from my car.... So i opened the hood check the dipstick and i was a quarter away from the center of the dipstick.... im due for an oil change in about 300miles... should i be worried?
