1) The right quantity is going to be in the owners manual or the supplement
2) How much F do you want to drop? what are you currently running and is that on the street or track?
3) See #2.

Basically what you want to ensure is that the fluids you use are up to Fords specs because if your under warranty and you're using a fluid that doesn't meet or exceed the specs you might be at a loss there. If you're looking at losing a bit of F then you need to look into external coolers as well.

Man I just realized I need to change my avatar. HAHA
 
Is weekend car and track days.
The bigger drop the better.
Yes I'm considering additional cooler system but before that I'd like to see what happen with different fluids.

5w50 is what i hear a lot (i think the 350 run it) for engine oil.

Don't know the way the trasmission is cooler. ( still new with this car)

First thing. I'm putting motul 600 for the brakes.

What you need, when you need it, no excuses.
1. Your oil capacity (including filter) is 10 quarts. Going to a 50-weight oil for track duty will work, but that's fairly heavy for daily street use in an engine designed around 20-30 weight oil use. A good 30- or 40-weight oil is a better idea. We use Driven oil in all of our track-day and race cars. The street/track oils have HTHS numbers significantly higher than Motul, Mobil1, etc. as they are designed around racing oil base stock. The ability of an oil to resist high temperature shear, and to provide a non-film lubricant barrier when the going gets really hot, is more important than the weight. Oil is one of those things that the internet will argue over ad infinitum. Not trying to sell you on oil (we do sell Driven as a convenience/service to our customers), just telling you what we've learned.

2. Ford Transmission Fluid is your best bet. No fluid is going to lower temps significantly, if at all. For that you need a cooler.

3. We've had the best luck in rear diffs and transaxles with Amsoil 75W-90 Severe Gear. We see less wear and longer oil change intervals on everything from track day to race cars. (We don't sell Amsoil.)

Thanks for your reply.
Really appreciate your advice.
I'll take a look on the differential and the engine oil.

You ever try Driven Racing rear oil in customer cars? Results?

I'd recommend Castrol SRF over Motul. I boiled the Motul at Sonoma. The SRF has been amazing so far. The price difference isn't as big as it appears when you consider that the SRF bottle is twice the size.

I know the desire to look for better things. I REALLY do :)

Sure seems hard to complete with the SRF for us mere mortals
 
How about Endless brake fluid?
 
How about Endless brake fluid?

I've used both Endless and Castrol SRF in my 2015 GT PP and noticed no difference. The car was running Pirelli DH slicks, and either Gloc R16 or Ferrodo DS1.11 pads.

I've switched to Castrol SRF due to cost, and the higher wet boiling point considering my experiences above. I haven't switched over the GT350 yet, but will use SRF.

Castrol SRF, BG SynchroShift II in MT-82 transmissions, Millers Oils CRX 75w140 rear axle lube and Motul 5w40 300V Competition Engine oil. Zero failures on any of these systems with over 22000 combined track miles on my 2011 Mustang GT, 2016 Mustang GT PP1 and my 2018 Mustang GT PP2 cars. And the original engine from my 2011 is still running strong and winning races in Captain Distraction's ST2 Mustang race car.
