If I was indeed a MYTHICAL cave dweller then yes I would be. However, I'm confused on whether or not you're asking me a question or yourself. You answered it so this added to my discombobulation.

I'm probably just going to stay with 5W-20 in mine as this viscosity has been out for years now and I'm not heard of engines dropping dead from using it and I know of plenty of 200,000+ engines using this viscosity. I also don't want to give Ford any reason to deny me warranty on my engine if something happens to go wrong with it at some point.
If you read used oil analysis results on many 5W-30's, they shear down to a 5W-20 anyway. I think too many people over analyze the oil thing but hey, it's a free country and people can use what they want.

Also does a fully synthetic oil shear down?

I'm not saying all 5W-30's shear down to a 5W-20 but some do. I've never read of any 5W-20's shearing down to a 10 weight, but I'm not saying none do. I've read of some full synthetics shearing down.
My main concern at this point is keeping my warranty intact. After it expires, who knows. The rest of the car will probably fall apart before the engine does.
Go to bobistheoilguy.com and read the section on used oil analysis. People post their used oil analysis results and post what the labs say. Interesting reading on all of the sections.

I have seen some oil analysis reports but it looks like Chinese to me. I have no idea what the heck all those numbers mean or what the report says.. lmao

In any event, I'm with you 2011 Kona Blue...I'm staying with 5w-30, as Florida certainly has "mixed temperatures, and I drive my Mustang "spritedly". It can do no harm. And I could care less about the mass CAFE and carbon dioxide reasons for pushing the use of 5w-20.
Great find dude!

Please, please post the link to that full article. This is what I've been after. The second engineer mentions a "mod motor". I'd now be interested in what he defines this as.

I'm gonna stay with my 5W 30 weight. After learning that Ford recommends 5W 50 weight for the engine on Gt trac pack it clearly shows me that weight can lubricate and flow to all the tight spec parts of the engine so 5W 30 will flow even better.

The mod motor he speaks of is the modular 4.6L motors. Bottom line here is that the move to 5-20 is now confirmed as to why and where as it probably won't hurt the motor long term, it's also not what ford thinks is the best. Also the second guy straight out says how 5-30 is better all around, which is something I've said on here several times (how's that for internet research?!)
Who's the buffoon now!?! Lol. And to think some people called this thread worthless. I move to make it a sticky!!!

I actually found that post on some mustang site but there was no link. Sorry. I'm gonna stay with my 5W 30 weight.

5W-30 would likely work just fine too, but I'll say this about 5W-20 - it's been the recommended oil weight for millions of engines from Ford, Honda, Chrysler, Mazda and probably more manufacturers for over a decade and I've never read a thing about motors having a higher failure rate due to it. Car companies are not in the business of making motors that fail early. They all know that 150-200K is the expected norm out of a motor, at minimum, and that while consumers will deal with expensive repairs to their cars, needing to repair major powertrain components is a different ballgame and they all are smart enough to avoid it. At least that's my theory.
Theory in point, I need to replace the power seat track in my car for friggin' $750 but I'll deal with it and not want to dump the car. But if I had a motor-related problem that was going to cost that much or more to fix, I'd be trading this car in fast.

Not the case. Honda for one has always used 5 or even 10-30. Always. And still does. Does that correlate to their forever lasting motors?? Idk. I'm sure others that have moved to 5-20 have done so for similar reasons. It's not like cafe is new.
I'm also not sure why after the skeptics have been calling for a ford engineer to speak to this, when we get TWO, it's shrugged off as one out of a thousand....
The bottom line is, (per ford engineers) we really shouldn’t be running 5w20. The switch from 5w30 in 1999 to 5w20 in 2001 (on identical engines) had nothing to do with wear or reliability issues and everything to do with Ford saving a few bucks by meeting CAFE standards. At the time Ford was fined $5.50 for every 1/10th of a MPG under the target average of 27.5 MPG for every vehicle manufactured. To help meet the target Ford changed from 5w30 to 5w20 and was able to improve mileage by 1/16th of a MPG and meet their goals. While most people understand the main function of oil is to protect the engine, Ford's primary concern in that respect is that the engine survives the warranty period. Do they last longer? Sure ford makes a great motor. But to the guy that got all butt hurt over me suggesting that ford doesn't care what happens out of warranty especially when they make money from it, I hope you realize that ford is in business to make money. Not fulfill your fantasies.

I'm still trying to use logic on how 5W 50 is recommended by Ford for a 5.0.Gt with upgraded suspension parts (trac pack) yet 5.0 with out trac pack gets 5W 20. Same engine, same specs , if Ford claims 5W 20 lubricates better because its thinner oil then how in gods green earth can 5W 50 weight lubricate just as good on the same freaking engines. It makes no sense. How can 5W 30 weight not lubricate awesome if 5W 50 does? Logic here ?
I don't care if people race or not. If the 5W 50 weight can lubricate the tight specs then 5W 20 weight is not any better. Were talking about the same identical engines yet two different oil recommendations.
My 3.7 will only get 5W 30 synthetic oil. I run my pony a bit on the hard side and with some upgraded suspension parts it will keep my engine protected from excessive wear.
