OK – the appropriate amount of Redline 5W20 and Amsoil 0W20 for you next change for a Ford 5W20 application is available to you free of charge but you can only pick either the Redline or Amsoil. Which one would you pick and why if you would like to comment on that?
Your pick - Redline or Amsoil for a 5W20 app.

Both are very good and I'm a fan of Amsoil but I would go with the Redline hands down.
Reason being, the moly, ZDDP, and super high HTHS. The ester base oil doesn't hurt either.
Redline kind of takes the debate out of the 20wt vs 30wt wars. It has an HTHS as high and higher than many 30wts so it flows like a 20wt, protects like a robust 30wt.

For your application you can't go wrong with either of them. Flip a coin.
How can you get cheaper than free?
Amsoil has given me nothing but excellent results... That said I have some Redline in the Garage to try... I would imagine both would be excellent in your application so go with what is cheaper...
Redline
Yep...RedLine.
If the 5W-20 is the only Red Line oil grade on offer then I'd go with the Amsoil 0W-20.
For my climate it has a lower starting viscosity and much high VI at 165 vs only 145 for RL.

Of course it's a hypothetical question and we know nothing of the application other than the OP lives in Texas.
Whether it's a 0W or 5W oil means little to me as far as cold starting performance is concerned as the SAE grades tend to overlap. Even where I live, it's the 40C vis that's the single best indicator of how light an oil is at start-up, and the lower the better. Amsoil is 49 cSt vs 55 cSt for RL. AFAIK, RL's 5W-20 has the highest 40C vis of any 20 wt oil hence it's low VI.
Having stated the above, I agree it's hard to overlook RL's superior base oil formulation and add' pac'. I'm just playing devils advocate for discussion purposes.

Agreed. A 0C viscosity would be nice.

Depends on if you have a warranty.
If you need a starburst oil, Amsoil XLM 5w-20, if not, Redline.

The engine is the Jag designed 3.9L V8 that was used in some Jags, Lincoln LS V8s, Thunderbirds, and some Land Rovers. In the Jag and Land Rover the manual calls for 5W30 but in the LS and Thunderbird the manual naturally calls for 5W20.
The car is rarely driven but when it is it could be a series of short trips or several miles at freeway or higher speeds. The car is 4 years old and has less then 9K miles on it. The oil gets changed once a year and currently there is Amsoil 0W20 in the sump.
Based on the numbers on Redline’s website the 5W20 is more robust then Redline’s 0W20 whereas Amsoil’s 0W20 is superior to Amsoil’s 5W20. Redline’s 5W20 appears to be more robust than Amsoil’s 0W20 and thus the request for opinions. Either oil is an overkill but that does not matter. I have never used Redline and was thinking – why not.

If 5W20 is the poisin then it has to be Redline no one makes a better 5W20! Just do not do a UOA on it until you have done at least 2 better yet 3 OCI's. WHy well unless you car is new and has never been ran on anything else it takes about 3 oil changes for it to chemically clean all the oxidation and other stuff left behind and it will skew the UOA results like mad! So if you cannot run it at least two time before sampleing the third OCI to see results do not waste you time or anyone elses becasue you will not get a good look at this oil or it's abilites you will only see what was left behind by the other oils!
