Whooaaaa!! I usually ask more questions than give answers, but I can tell you from first hand experience that you do NOT want to use any of the oil flush products. I just tried that route in a little Mazda my daughter has. We lost the lower end of the engine because a piece of the sludge was washed loose and lodged in a hole that oils a bearing. After that incident, I researched and have found very few experts who will recommend this procedure.
