The next time you're at the store, pick up an extra paper towel holder. When you get home, install it in the front section of your garage and insert a roll of towels. The towels will be accessible and handy for checking the oil in your vehicles and other quick clean-ups. The holder will also help you avoid fumbling with loose rolls or searching out rags.
Be sure to test your back up generator every year, especially prior to the cold seasons when it is imperative it work. Also check the oil level, spark plug and fuel filter as prescribed by the owner’s manual.
