It seems to me that this whole "true" synthetic argument misses the point. What exactly is a "true" synthetic? Is Mobil 1 somehow more pure? Isn't the final result, the most advanced technology and best protection for your engine, the thing that matters? Royal Purple seems to be dedicated to staying on the cutting edge of lubricant technology. It's the proprietary additives that make the difference in Royal Purple's case , right?

I'm glad for your post Tone, makes me feel a little better about deciding to use Royal Purple products in my VX.

Now I just have to find someone I trust to do the flush. My mechanic can't do it and I didn't like my last experience at the local Isuzu dealer.
