Definitely not an issue exclusive to Ford by any means.

I just had to change the hpfp pressure sensor on a friends truck cause it was running rough at times then would die. Put a new sensor and harness on it. Its been good scense. Truck had 128000 miles on it. The code was P-0194

I had the same problem about 20,000 miles ago. Not a big deal at all.

The shop told me I should be using more or a different fuel additive.
I used Standyne every few tanks for water but shop says I should be using something with oil in it for more lubrication.
2 stroke or transmission oil and this probably wouldn't have happened

Senix is right, 2 stroke oil in an emissions equipped vehicle will mess up that system fast. As for lubrication, if there's any bio-diesel in it, like as little as 2%, that should take care of any lubrication issues. Stanadyne is as good as anything out there, and works with your emission system. Perhaps you need to use it at every tankful.

the fuel pump is in between the fuel and the filter so the pump is protecting the fuel filter?

They don't. But, what does happen is when the HPFP goes bad, or an injector does, the metal shavings end up in the return line going back to the tank. The shavings in the tank reveal that something is majorily wrong with either the HPFP or an injector.
