On my Kia sedona mini van I had the oil changed about 2000 miles ago and it needs some now I believe, but I don’t recall if they used 5w or 10w, so does it matter much which type I put in? Also, checking my oil, the mark is between the two lines, if the line was 0 and the top line was 10, it’s at about a 8 right now. Should I top it back to ten, aka full or just monitor it and refill when it gets closer the the bottom marking?
Also with my antifreze, in the resevior it is using the same system probably a 3. A couple weeks back it was at that level, I put in about enough to get it to a 7 level, and now it’s back down to a 3, but not sure why. It seems to like that level as it has not gone down anymore. Should I level it alone or put more in?
