winter is here: time for 0W oil
duluth mn winters are harsh. I use syn oil in the winter since i park outside. i see mobil 1 0w-30 and 5w-30 are the same price. $22/4.75liter. my car says 10w-30 summer and 5w-30 winter. a 0w is going to have slightly better flow in cold weather so thats what i am going with. my other car uses 0w-20. so both of my cars will have 0w.
