Some posters on this website do not like Amsoil for their marketing but hey its the oil business. All the oil companies have their own way to market a product. I for one have always supported the Amsoil product. My only issue is the price...I thought the oil change was costing too much. Despite the price Amsoil makes a product superior to whatever is found on the Walmart store shelf.
In particular its 0W-40 is thicker than any other 0W-40 on sale at Walmart and contains a superior base stock.

So I think if you are looking for a better solution than the Mobil 1 0W-40 and have the cash to spend take a look at Amsoil. If you worried about that Escalade or F150 with the 3.5 I personally believe running Amsoil 0W-40 will be the best solution.

I'm pretty skeptical that the issues with either of those engine families are something that can be mitigated with boutique oil. Design issues and poor parts quality can't be bandaided with oil.

Use quality off the shelf oil and change it regularly.

Skyactiv beat me to the punch by a hair.

Well the thing is some of us simply cant sell our cars and get another one so we need to do something.
 
I think you'd be better off saving your money for a new timing set for your pre 18 Ford or new lifters for your 5.3. 0w-40 might help with a 6.2 but as far as the evidence goes, it's a crap shoot at this point.

Noted, @Pablo, I'll watch my terminology and try to check my attitude.

Amsoil is great oil.

Haha I didn’t detect an attitude
 
Im not saying this is the "cure all" for the engine. Im just saying if you going thicker and looking at something like Mobil 1...and have the money to spend...Amsoil is a better oil than the Walmart oils. The cst@100 for that Mobil 1 0W-40 is 13.8 according to Mobil website. Amsoil 0W-40 is at 14.8.

Viscosity is a major factor in many of these modern engine failures. While a boutique oil might not 'fix' anything, in some engines, not all, adequate viscosity will. The Ford 3.5 Ecoboost and the 5.4 3valve are among them. Add in 10,000 mile OCI's, variable oil pressure systems and we have a perfect storm.

5w-30 and 5k changes got our 5.4 3V Expedition to 270k without issues. That's just annacdotal evidence at best, but it worked for us. It doesn't see a ton of miles anymore but I'm hoping for a lot more use out of it. Maybe someday if it starts ticking I'll throw some new valve followers in it but so far so good.

The 5.4 is a motor known for longevity regardless of motor oil used. My son had this motor in a full size van and took it to "quick lube places" and it was high miles when he sold it. Zero issues.

Not all. A lot of 3 valve 5.4s have early timing chain and guide wear. They also tend to suffer from insufficient top end lube and low oil pressure, often due to blown out timing chain tensioner seals. Due to the top end oil starvation, the cam bearing surfaces get worn and the cam followers wear out causing dropped valves. Then there's the variable cam timing phasers...

Note that the SS 0W-40 is NOT a Euro oil, so it's not a replacement for M1 FS 0W-40 (or ESP X4 0W-40).

Without testing it's tough to make that claim based off data sheets. How much does AZF shear in use? HTHS starts at 3.8, same as M1 0w40 ESPx4. Which you can get under $6/qt with AZ deal, and we know it has very little shear. Virgin KV100 is borderline pointless stat.
 
Would be impossible to really know how it would compare to other 0w40s off the shelf being they're tested against different specifications, although for the most part ILSAC and ACEA additive packages had converged with oils being more similar than different.

The M1 FS 0w40 no longer contains ester per virgin oxidation value. Does that mean it's worse? No idea. They could be using what ESP 5w30 is using.

It is interesting though that the Mobil 1 Racing 0w30 and 0w50 are PAO based. Also, interesting that the ESP 0w40 and 0w30 contain ester and the ESP 5w30 doesn't.

Lingenfelter is a good endorsement of how good the SS line is IMO.

I'd have a hard time passing on 0w40 x4 though. May not last as long in service as SS, but everything else should be top notch.

What’s Delvac 0w40@40C, also sold at Walmart?
More important, than viscosity at 40C, HTHS is 4.1 and the flashpoint is 240C.
