Personally I've never had a single success with so-called penetrating
oils, not one time in 40+ years, not ever. The only thing I've found
that's guaranteed to work is heat; not just butane or propane heat, but
oxy-acetylene heat. Heat the ****er up till it glows bright orange and
away you go. Never known it fail.
Are you using the wrong stuff? ATF is the best. Some people think WD40 is a penetrating oil, but it's not.
40th recipe fro a Water Dispersant is it not (or is that some sort of
urban myth?).
I use a ATF/acetone mix (50:50) it has never failed as a penetrant it
also (mainly ) gets used as a 'rust eater', it helps when you are
removing surface rust.
I agree heat will shift just about anything but engine bays etc are
not the place for naked flames
