I'm kind of confused on which one is the German Castrol synthetic?
German Castrol (GC) is a 0W30 oil. All you need to do is go into an Autozone or other automotive store, look for the Castrol Syntec bottles that are labelled 0W30, flip the bottle around, and look for the "Made in Germany" in fine print on the back of the bottle.
It looks exactly the same as the other American-made Castrol Syntec bottles, but is distinguished by the 0W30 grade as opposed to 5W30 / 10W30 / 5W50 / 5W40 / etc.
Also, I definitely agree with others here about the idling!!! Terrible for the engine and the oil.
There is no need to be concerned about the battery. I design equipment that is sold to automotive and industrial lead-acid battery manufacturers. My company also engages in a lot of battery testing. We do more in depth tests and autopsies than the manufacturers do! A typical automotive battery in good health should still be able to start the car even after 2 months of sitting unused. I personally recommend using an automatic battery maintainer if you are going to leave the car sitting for more than 2 months at a time. Also, if you get more than 3 - 4 years on your OEM battery, you're in good shape!!!
But in all honesty your car will be fine sitting around for several weeks at a time. I travel a lot for work, and my car sometimes sits for 2 weeks unused. Starts and runs fine, summer or winter. No issues at all with it and its almost 6 years old now. When I'm home, I drive like crazy (65-100 miles minimum per day). My VQ35DE has almost 120,000 miles and still runs very well. I typically run a thick 30 grade syn or a 40 grade syn in mine btw...
