10w30??? not 5w20???
Last weekend (Sunday), I did another car with Amsoil MTG. We added the Steeda Tri-Ax shifter at the same time. These two mods allowed the owner of a 2012 5.0 car to slam through the gears while grinding and missing gears is a thing of the past. A bit more interior noise from the high durometer bushing in the shifter, but no added noise from the new fluid. The owners first remark about the change was, "This is how the car should have driven from the factory. Huge improvement."
The coyote engine in other countries is actually spec'd for 5w30...
And those countries would be...?
The Boss 315 and Boss 335 take 5w-20. Try another country or produce some evidence.

Someone on another forum found this link:

Makes it hard to argue otherwise.
That said, I was one of those people who fully expected that Ford would use a heavier oil in the supercharged Miami engine, given the evidence of the Ecoboost and GT500 engines with xw-30 and xw-50. However, even before a word was written about the oil selection, pre-launch press photos from Ford of the supercharged Boss 315/335 engines clearly showed "5w-20" on the oil cap. Hence, the recommendation has always been 5w-20.
On Australian forums after the car launched, new owners were posting "I can't believe that this watery stuff will protect my engine" and so on. Same issue, different country. I guess enough people were going off the reservation that Ford and Castrol put their foot down with the letter in the link.
See, now when I made my comment I was talking more about the 5.0 F150s, as I do believe other countries are recommending 5w30.
What countries other than Canada and the USA actually sell the F150's? Mexico maybe? I couldn't find any references to it in Europe, and I've never seen one there. The F-series trucks are not listed on Ford websites anywhere outside of North America that I could find, but maybe I'm not looking in the right places.
In Australia, the only cars to use the Coyote engine in any form are the FPV vehicles we've already discussed. All the trucks and utes top out with around three to four liter turbo-diesels. Only one version of the Ranger even has a gasoline engine, and it's a four liter inline six. Taxes make big displacement V8's too expensive to buy and operate for most people, so they're pretty rare.
Just swapped the fluid to mtg. Definate improvement over the stock fluid.
Just finished swapping the DCT fluid for MTG. The MTG shifts so much smoother from the get go in 35 degree weather than the DCT does after traveling a hundred plus miles in 45 degree weather. Ford should be ashamed of theirselves for recommending that garbage in their TSB.
