We've been gone for 3 1/2 months with the Bonneville sitting in the garage the entire time. The good news was that after I reconnected the battery, it started right up and ran perfectly. The bad news was that I noticed a very thick lime green fluid on the garage floor under the engine, towards the front and to the passenger side. I still run Dexcool so that isn't it and for the life of me, I can't think what this might be. For what it'* worth, there is no smell to it at all.
