Q Should I shut off the motor when I'm idling my car, or does it just take more gas to get it started again?
A Idling gets 0 miles per gallon. If you are going to be parked for more than 30 seconds, turn off the engine. Ten seconds of idling can use more fuel than turning off the engine and restarting it. And when you start your engine, don't step down on the accelerator; simply turn the key to start.
If you're at a drive-in restaurant, for example, an alternative to idling is to park your car, walk inside, do your business and then go back to your car.

Low-VOC caulk Q We recently had an energy audit of our house, which was built in 1997 and is in great shape. The auditor suggested that we caulk around our windows. We've been trying to find a good caulk that's "low-VOC" (volatile organic compound), but with no luck. Any suggestions?
A For low-VOC caulks and sealants, look for:
• OSI Green Series brand of sealants and adhesives. (Go to Greenseries.com, scroll to bottom and click "products" tab.)
• Chem-Caulk 2000 Construction Grade Hybrid Sealant and 2020 Architectural Grade Hybrid Sealant products by Bostik Inc.
