Next I'll try Seafoam or Rotella before the oil change. It has become my personnal vendetta to find the cure (short of an engine rebuild).

& thanks for the kind words. I'm probably now back to the acceptable limit for Isuzu (1 qt every 1000 miles). I was burning a quart every 300 miles.
So how are you gauging your test results? Do you commute to work & burn through a tank every week? I wonder if one tank per experiment gives an accurate comparison... ? Do you think outside temp has anything to do with it? Like summer versus winter? I never did any tests regarding oil consumption or burn or whatever is going on.
