Fuel Saving Tips
Lug nuts, if not lubricated occasionally, can seize or "freeze" to the studs due to corrosion. Repairing them can be expensive, too, and having to call a tow truck for a flat you can't remove is even more expensive. The next time you change or rotate your tires, pick up some anti-seize lubricant at your local auto supply store. Clean the stud threads with a wire brush and wipe them with the lubricant. It's formulated to prevent the lug nuts (spark plugs, too) from seizing and won't allow them to loosen as you drive, the way other lubricants might. If a lug nut does freeze to a stud, try spraying the nut and stud with WD-40 or Liquid Wrench. Allow it to penetrate for 10 or 20 minutes. Use a heat gun to apply heat, and then use a ratchet wrench to remove the lug.
