I live in Orlando, FL and now have an unplanned trip to Chicago next week. I had the oil changed a few weeks ago at the Ford dealer with the standard 15w-40 weight conventional oil (they had a $60 special for oil and filter). The low temperatures in Chicago this time of year could be around 0 F. My question is will my engine be OK for the couple weeks I will be Chicago with the current oil? :dunno: I do not want to damage the engine but I would also rather not have to change the oil again. Anyone have thoughts on this. Thank you.
