Like many of you, I too am old school about my car's oil. It took me a long time to get use to the multi viscosity oils, and until I purchased my CT I have never had any experience with synthetic oils.
My dealer tells me that my CT comes with synthetic. I know that some of you disagree with this based on information in the owner's manual. I don't know the answer to this, but one thing is apparent to me, Honda wants us to use synthetic.
I have always been under the impression that using synthetic oils allowed the user more miles between changes, but as I said, I don't really know this as fact. This thread and my CT has caused me to have to learn more about synthetics.
I found a February 2009 article published in Car Craft that is about Synthetic Versus Conventional, talks about Viscosity, Temperature, and Horsepower. It's a good article backed by tests, and a recommended read.

This article does not address the question of how far we can drive between changes, but based on the information and supporting tests it appears that our cars can go much further between changes than we are use to with conventional oils. I will have to continue to research this issue and learn more until I feel comfortable about it. Richard
