I read the Edmunds board and I know who you are referring to. He goes by ruking1, but I don't think he comes in here (not sure why, he seems to like to talk about oil a lot)
I question the fact that he doesn't do oil analysis on this car. Considering he has a new Z06 Vette, he should be aware that these engines put a lot of copper into the oil at first. So going right to a 15k interval is crazy until the engine settles in. And even then, he might find he needs to scale it back to 10k.
He is basing his choice on past experience with other vehicles, mainly Toyota Land Cruisers, where he has gotten a combined total of 600k on them using this 15k oil change schedule on M1. One of the vehicles alone went 250k. But that same rule can't be applied to all vehicles. Just because he had success in one type of vehicle with 15k intervals doesn't mean he will have the same results with others. If he tried a 15k interval in a new Toyota V6 he'd be in big trouble.
By the way, he doesn't do the extended intervals to save money. Much like me, he does it so he doesn't have to change the oil as often. I change oil in 4 cars for my family and I don't feel like doing it every 3k, I'd be doing close to 20 oil changes per year! The older I get (I turned 33 today!) the less I enjoy getting dirty and getting cuts and scrapes (which I always seem to get with every single oil change I do)
