Its just overrated synthetic with some purple dye in it and the dye is what causes problems I think.

It's used in a lot of the trucks at work. The dye is broken down and dissolved in the first few hundred miles. If the Air Force goes out of their way to use it at the recommendation of the analysis dept (does analysis on all engine oil, including gasoline, diesel, and jet turbine engines), then I will definitely run it in my car.

I'm so glad you're still here with us!

I don't really care what people in a lab say about how good a oil is. I see what happens in a race engine when Royal purple is used.
Your motor looks clean inside so I assume it was treated decent. I'm sure your engine isn't turning 6000-7000 rpm almost every minute of it's life. I don't remember the last time I started my pull truck motor to hook to a sled and go for a Sunday cruise, down by the lake. J/k
Like I said in my first post, it should not cause much of a problem in our cars. I'm afraid it will turn to tar in my truck or my race car so I won't put it in them. I use the oil I order for my race cars in my GP I know its good stuff.
I have four seasons on my BBC and the only thing that I do to it is change valve springs every year put new plugs in and adjust rockers every weekend. I still have 70psi of oil pressure at idle hot so I don't even worry about pulling the pan and checking the bearings. I might pull the pan this winter but I doubt it. Just put new heads and cam in it and put it back on the dyno.
Back on track, as far as the Synthetic VS Regular oil goes I would look for a oil with Moly or ZDDP in it. The only why to find them is in race oils. Damn Government took all the good stuff out of your off the shelf oils.
