'05 300 question..

No, that's not an Amsoil product- its all just snake-oil anyway. You're thinking of Slick 50 Intelligent Lubricant, with neuropathic PTFE networked particles. "The lubricant smarter than the people who buy it."

Are you sure about that? I thought that they were relatively new since they did require more room. Sure looked like my 91 Taurus engine was just attached to unibody. I'm sure it was strong unibody but not an isolated cradle.

Like most others on this group, Steve knows a whole hell of a lot more about cars than you do.

Those Darts and Valiants you love to bitch about had subframes holding the engine and front suspension; the subframe was bolted to the unibody.

Well, see, being wrong is just what happens when you just guess at it ignorantly, Art.

Most assuredly, your 1991 Taurus had (has) a front sub-frame.

I know that Chrysler B-bodies had bolt-in front subframes right from the beginning. My '69 Coronet has one, my friend's '67 GTX has one, and I've seen them all the way back to the '61 or '62 models. The C-bodies have a "stub frame" that is welded to the unibody, but conceptually its the same as a subframe. The F/M/J bodies of the late 70s and 80s (first models were Aspen/Volare, last were the Diplomat, Gran Fury, 5th Ave). had an elaborate bolt-in subframe, isolated by big rubber donuts (replaced by iron spacers to improve handling in copcars), that carried the entire front suspension including the transverse torsion bars. I'm pretty sure the K-cars and OmniRizon also had bolt-in subframes, but I never had much to do with those after a bad experience with a '78 Horizon.
