Breaking Loose O2 sensor

I'm going to change the o2 sensor this weekend on a 88 300E and I was wondering what I should use to help break it loose. I'm presuming that it's best to do it with the car cold, but I'm wondering if something as common(sitting in my garage) as WD40 will work or will I need something more potent.
Thanks,
Dino
