One thing that is very helpful is to make sure you check it in the same place every time , e.g. in the garage before leaving for work. it's important to check it on level surface ,not only level front to back,but side to side. It is VERY sensitive to any incline. When I first got it ,I would check it too often and I would get readings all over the map ... which immediately translates into a hundred imaginary oil burning problems. Save yourself the agony and check it in the same place under same conditions . Its right where it was the day I bought it .
