Of course people will argue about this logic since it's not as cut and dry as you make it out to be. We had a huge thread about this not too long ago, and despite several requests to provide any verifiable evidence to prove that a) Synthetic is cheaper to run, and b) It can generally (meaning in most driving conditions and most cars) be run twice the OCI as dino, none was provided.
And there is an overwhelming evidence, in our UOA forum for example, that most people that use synthetic oil, change it at 5k intervals anyways. So, while everybody likes to talk about the superiority of synthetics and extended OCIs, few are actually taking advantage of virtues synthetic oil can provide.
I've noticed too that a lot of the synthetic UOA's are around 5k or so. You would think BITOG'ers would be going longer.
