broken lug bolts
someone pleas help!! I just recently bought a 1989 300SE. While driving it, my wife had a flat tire and had the car towed home. I proceeded to try to change the tire only to discover that someone had either used a very powerful air gun or a torque bar when tightening the lug bolts. After a very frustrating week, I have accomplishe getting three of the lug bolts off, totally stripping the nut on the 4th, and breaking the fifth one about halfway down the bolt. I have tried to get it with an "easy out" but to no avail. I really need to get this car one the road again.... any suggestions would be greatly appreciated!!
Thanks,
JD

WD40 is very good, but I've found the best penetrating oil on Earth is called Kano AeroKroil, it is absolutely fantastic at loosening all bolts. It's made by Kano laboratories at (615) 833-4101 and my 10oz can has lasted a long time- it's not expensive. That's my recommendation for a penetrating oil.
Also suggest spraying Aero Kroil thoroughly around lugnut base and let soak for around 15 min. first before trying to loosen.
