To charge/tender or disconnect

Hello guys,
I'm going to India for 6 weeks, so, I'm renting a garage in my apartment complex, and planning to store it.
1. Filling up the tank to full, shall I add any additives or not required? I had left the car for 5 days and saw a decline in fuel, after I return and there is no way someone could drive the car while I was away, as the keys are with me. I complained to the SA and he said it is nothing. Will test it out this time though.
2. Should I disconnect both the batteries? or use battery tender to maintain it?
If disconnecting, which battery should go first and which terminal to be removed first?
If battery tender, which one should I connect to, the main or the aux battery?
3. Will cover the exhaust ports (worried about rodents), should I cover anything else?

Anything else I need to know before storing?
Thank You.

6 weeks..no big deal unless you been having battery problems. I once left my E63 at the airport for two month while I was in Singapore. Other than the low rider look it started right up.

Why would rodents crawl up your tailpipe, when there is nothing to eat but metal? If they build a nest in there it will give you a thrill to blow them out at start up when you return. I think for 6 weeks you will be fine. Think of all of the used cars sitting on lots for way longer than that and no one does anything special for them.Have a nice vacation!

I have regular suspension, and so far the batteries feel fine. I get eco mode within 5mins or less than 5miles after a cold start.

Put some Sta-Bil in the fuel and don't worry about the rest of it. The car will be fine.

Nothing really needed. Battery tender would be the only thing I would consider doing but mainly b/c I have airmatic.

I've had the battery in the wife's E250 drain in just a couple weeks of vacation. This was in the cold winter, though. I would recommend a smart charger.
No fuel stabilizer is needed for 6 weeks.
