Try another angle if you try to loosen on the side that your wrench is on you will have less mechanical advantage.So if your ratchet and socket is on the 6 oclock bolt and the ratchet handle is up it is easier to loosen than if you do the same thing with the 12 oclock bolt. I hope that makes sense

By far, the best penetrant for this job is a 50/50 mix of ATF and Acetone.
