Well, my Blackstone Lab's oil report showed after 5,100 miles from dino oil, "...no contaminants or other issues were found" and even suggested to run for 7.000 miles on next oil.

And dino oil is not recommended in new cars anymore.. I'm surprised people even mention anything but synthetic nowadays.

Just because it hasn't been broken down after 5k miles doesn't mean its superior to synthetic (especially when the car has been ran hard).. Like I said, synthetic has been proven to be superior in virtually every category (and not that much more expensive).
im sure some people would contest this... synthetic in general is good especially in FI applications, but royal purple as a brand may not be the best..
you could argue this for days, but I would recommend synthetic for the peace of mind.
^^^^ I'm sure you are right^^^^^^ I was told the factory oil was not synthetic. I have used mobile 1 but have now switched to royal purple as I to believe its one of the best n the market.
