Yeah, but isn't there a write-up in the 4th Gen Forum about how it's not good to flush your system and use synthetic until you hit about 90k miles, then it's REALLY good. Maybe I'm mistaken, but I believe that it was on Syntheic oils, but not 100% sure. If it is though, then I feel you made a mistake doing that to your I35 unless it has over 90k miles, which I doubt.

Can someone tell me how this makes any sense?

Why not Pennzoil ?!? There is nothin against it written in the stickies in Fluids section on Pennzoil, but they did say against Valvoline (don't remember if it's against synthetic valvoline though!)

Says "Stay away from any Valvoline ..." but it does add the phrase "if going over 3000 miles" But I am not sure what that sub-par analysis results mean and are!

This guy actually recommends Penzoil which make no sense because it contians Parafin, which is a wax like substance. Look inside the vavle cover of the engine (remove oil cap). On vehicles that have used a Parafin based oil ( or have run nonparafin oil for exesive periods of time), the entire area has masive oil deposit build up. NOT GOOD!
I think I will choose to NOT heed his advice and stick with my Valvoline...

Well that is all fine and good, but those articles were sponsored/ written by Pennzoil. They are by no means nonbiased. What they say could be right, and all of this parafin, wax, sludge talk is myth. Or they could be wrong, and the various comments that I have heard about Pennzoil through out the years by various inviduals are correct. I am NOT one to have enough independent knowledge or facts to decrypt this mystery, so I have made the descision to STAY AWAY from Pennzoil just to be on the safe side.

If you do have it, switch oil, buy engine flush from your parts store and use that for about the next four or five oil changes (you usually put it into the dirty oil and run the engine for 15-20 min. before oil change). Also, the more you change your oil, the more that stuff will be eroded away by the fresh oil (oil contains detergent). If it is really bad, start changing your oil every 2000 miles.
When I got my 92 Acura Vigor, the previous owner had followed the Honda recommended oil change schedule of 7500 miles w/ new filter every other change (every 15000 miles!!!) for about 80000 miles. I had that burned oil residue all over. After about ten 2000 mile oil changes with engine flush, i got rid of it.

As far as to why Pennzoil uses parafin, I have no idea.
