Traditional or Synthetic? Which one ?

[TomsKingRanch]

Royal Purple in my 2007 F350 King Ranch CC 4WD SRW 6.0L engine, differential, rear end, and EVERY vehicle I own! Two Toyota's for my wife and daughter as well as my MB 560SL Roadster. Have had great results with it , my son is already eyeing RP for a car of his own in a couple of years.

Just switch over is all that is needed. If you want extended oil changes, you must get your oil analysised from some place like Blackstone Laboratories

Don't worry, you will be fine. If not, it is best to catch the problem before more damage happens. Excessive fuel is what you want to be looking for. They will tell you in the analysis.

how will synthetic oil lower your LEAD content ?

I'm betting on that the dino isn't providing the necessary lubricity for the bearings in our 7.3's case. I'm no Mr.Peabody,just taking a swing at it
