A single tested bottle is not representative of the whole population. That is akin to taking one American and one Canadian and saying that Americans are smarter because that person got a better score on the IQ test. A single person is not representative of a country nor is one test always a good indicator of intelligence.
Listen, the answer is: IT DEPENDS.
If you want to label something as "better" you have to qualify that defines "better". What are the conditions, what are the metrics? Are we factoring in cost or are we looking for froghairs? Otherwise, it will go around in circles. Conventional oils are good and are better than their predecessors (and often part-syn anyway). Syns still do a lot better under extreme conditions and offer a bigger window of performance/protection. As to which is better, you have to define what is to be considered "better" and then we can debate it. Otherwise, it is like debating the quality of the weather... as warm and humid summers day in the south is "tolerable" for me but "intolerable" for you. We need metrics.
The "Yes/No" answer does not exist.
Oh, and a guy from Arizona might be better at understanding cold stars, as place does little/nothing for knowledge. "Warming" up a vehicle is more for the driver than the mechanical components. Any "use of fuel" while stationary is going to be the biggest polluter/waste, so basically if the vehicle starts, start driving (and amend your driving style accordingly to the conditions).
