Rob I don't know if you were talking about my post on the other sythetic thread, but I just to clear it up, we were talking about older engines with much larger tolerances/clearances. 6.0s love synthetic and those problems we were talking about don't really apply to newer engines. Hope this helps clear things up :thumb:
