water from exhaust when first starting

[Av8tr]

I had a chance to drive my C6 yesterday for the first time in a few months. I've been traveling and only got to drive it every 3 months or so. Battery was disconnected and on a trickle charger. Took it for some excersise for about an hour. When it first started up, I had a lot of water coming from the exhaust pipes. Not a huge amount but enough to leave small puddles on the ground while I waited for the car to warm up and oil to get through the system. I drove it for about an hour and it ran great. No smoke from the back that I could see. No overheating or fog on the inside of the windshield.

I use AMSOIL for lubrication so oil wise I should be ok. I even changed the oil before I left so there is probably less than 1000 miles on the oil.

Anything to be concerned about?
