I recently changed my oil with some 20-50 and noticed that the old engine oil had so much metal flecks in it that this may have been the first oil change on it and it has 3200 miles. I bought it from the dealer with 900 and there is no record of a 600 mile oil change. SO my question is before the oil change my idle was around 1380rpms maybe a little higher. After the oil change i notice that the rpms dropped to around 1220. Is this ok???
