Boom. The Boss also has blocked off oil squirters doesn't need to stick to a thinner oil to make it though those when up to temp.

Knowledge.

To protect your engine and engine’s warranty, use Motorcraft SAE

WSS-M2C930-A. SAE 5W-20 oil provides optimum fuel economy and
durability performance meeting all requirements for your
vehicle’s engine. Refer to Maintenance product specifications and
capacities later in this chapter for more information.

Since you conveniently overlooked my original comment that stated 5w20 is fine for the average user, I'll say it again. 5w20 was selected for fuel economy reasons, but still provides enough protection for the average user.

It's not because of the design of the engine. If the tolerances were such in the bearings or the tiVCT didn't work properly with heavier weight oils, it would specifically state that. not to mention you wouldn't see 5w50 recommended for the Boss which uses the same tiVCT mechanisms.

So why no comment about Chrysler and other manufacturers? If the trick worked for Ford to eek out better fleet mileage, other manufacturers would have piled on.

The VCT in the 4.6 and the TiVCT in the 5.0 are not the same. The VCT is completely hydraulic action. TiVCT is partial hydraulic and partial 'cam torque actuated'. But now you're mixing apples and oranges.

The Coyote's TiVCT benefits from cam torque actuation. Instead of high-pressure oil energizing the cam phasers, CTA uses the valvespring energy torquing through the camshafts. At certain periods of cam rotation, valvespring pressure tries to advance the cams, and retard them at other points. This snappy back and forth energy is traditionally dissipated uselessly into the timing chains, but with CTA it's used to power the cam phasers. Engine oil is still used to fill the cam phaser chambers and thus hold the new cam position, but not physically advance or retard the cam-that work is done strictly by cam torque from the valvesprings. As such, there is no hardware in CTA. It is only a strategy.

In fact, in exchange for some crafty thinking and hard-won computer software, there are less hardware and cylinder-head-design headaches with CTA. The control mechanism for shuttling oil in and out of the phasers is a simple solenoid because the three-way shuttle valve is not required. High-pressure oil is also not needed, so the engine's oil pump can be downsized and horsepower saved. Nor are dedicated oil passages to the phasers required. Instead, the Coyote's TiVCT with CTA system siphons off bleed oil from the nearest cam journal.

Motorcraft 5W20 full synthetic and live with a clear conscience.

I'll counter with the fact that there are guys running 10w30 in their 5.0's without a problem.

My car that I'm driving has 5w-20 synthetic. My car is running fine too. Too much talk and worry here about this. What did you decide to put in your car?

Interesting conversation everyone, thanks for the input . . . though I got a little more than I bargained for!

I ended up using 5 quarts of 5W-20 plus 1 quart of 0W-20 Mobil 1, since I had a 5-quart jug plus some quarts of 0W-20 laying around that I use for my wife's Camry. I don't think the 1 quart of 0W-20 is going to make any significant difference, but figured it can't hurt in the winter. It is cold here now so I had a Ford dealer do the oil change (car was in for some minor warranty work before it runs out) and they didn't raise any objections to the 1 quart of 0W-20.

Interestingly enough, and at the risk of resurrecting this dead horse, Toyota recommends 0W-20 for the Camry (and other cars I suspect) for "maximum fuel efficiency" and they don't seem to have any longevity issues . . .

For what it's worth, I changed my oil last week and put in 5W30 for a tad bit extra protection. The reason I did this because I routinely drive 80 - 120 MPH for long distances, with spurts up to 130-140. I don't know how Ford tested their engines, but I imagine a slightly heavier oil wouldn't hurt. The Boss has pretty much the same engine and it uses 5W50 so I figure going to 30 won't hurt. Now, if 5W30 causes me some engine damage then IMHO this engine wasn't worth a nickel to begin with and was going to fail regardless.

Don't know exactly what your question is, but where I live in a region where many roads and highways have no speed limits. Where there are speed limits they are seldom enforced. If you want to know the truth 130-140 around here is not very fast. People pass me going so fast I think the are going the other way.

I just didn't know where you could "routinely" and safely drive at those speeds. Please be careful.

Like I was saying, if 5W30 causes me some oil related engine damage then IMHO this engine wasn't worth a nickel to begin with and is going to fail regardless of what oil you put in it.
