JOEE, when I hear yours and similar stories, I gain a sense of relief that there is still hope (other than a removal and break down). I keep saying I'll go another few hundred miles. I guess I'm good for a few more.

There are so many others in my area running similar strokers and they all use 20W50 per the advise of the builder. I seem to be the only one experiencing this prolonged problem. Most of the guys seem to see a virtual end to consumption in 1,000 or so miles. It runs so well, I just hate to mess with it.
