That may be true they are not regulated the same I dunno but I do know a company has to build it's reputation on good products. Not sure I would call them a racket lol.
My conventional oil turns black much faster than synthetic. That I have used anyway.

Oil turning black means nothing except it is filtering out contaminents. What is more important is how quickly the oil breaks down and loses viscosity and detergent agents. Most dino oils turn black after a few thousand miles.. You need to send out the oil to have it analyzed to determine what is going on.
Synthetic oils have been hyped by the oil companies for years. I've run dino oil in dozens of cars that all have gone over 100k miles with zero engine problems. It all comes down to maintenence.
