As another sign that gas prices are going up and up, someone siphoned half a tank of gas from my tank last night. If they were willing to do it to my car, they'll do it to any other one; including yours.
The best course of action is to store your car in a locked garage every night. If you're not able to do that then I encourage you to get one of those lockable gas tank caps. It's $20 well spent and is a lot cheaper than the gasoline that it protects.
And that is your Warrendale Tip of the Week.
