I took out 8 oz. of power steering fluid from my 97 Lincoln town car power steering reservoir and then added 8 oz. of Trans Tune, then drove 15 miles. The next day I drained the power steering reservoir and filled it with fresh power steering fluid and drove 10 miles. My question is can I repeat this procedure again and add the remaining 8 oz. of Trans Tune that I have leftover and drive for a few days (100 miles) and then drain the reservoir and fill it with new power steering fluid?
