Mach 1's also have an external factory oil cooler.10Qts? I didn't realize the Mach 1s had a different oil capacity? do the 18+ plastic pans hold that much more?
This.The best source for what oil to use is the manufacturer. They “Own” the engine until the warranty runs out. Adding the wrong oil can cause the warranty to run out instantly.
that motorcraft (Castrol) oil is solid for race trackThis.
For the first time ever I am taking the new car to the dealer for oil changes and following the manual for oil change intervals for track use. And aside from track wheels/tires and camber plates, the car is going to be left stock.
I personally use the standard 5W20 and change 3 times a season so around 2000-3000 km's between changes and a few track days though I do think 5W50 will probably be better.So my 2023 Mach 1 owners manual specs 5W50 for track usage and it says oil change after 1 track weekend or every 4 hours of track use.
What RPMs are you turning? If you're not redlining every shift then you might be OK, but even at that I would not use 5W20 on track, in my 2016 I used 5W30. I figured a little more viscosity would provide more protection especially on hot days. Start up wear would be worse with 5W30, but only marginally. That car was never winter driven or used as a daily driver so I felt the trade off was worth it.I personally use the standard 5W20 and change 3 times a season so around 2000-3000 km's between changes and a few track days though I do think 5W50 will probably be better.
My car is stock Gen 2 so the red line is 6850 I think I usually do 6600-6700 RPM shifts and my CHT reaches as high as 240F at hot summer days. This will be my 6th season with the car and so far I turned over 47 000 km's with the car and have 16 track hours and 1408 km's on track (874 miles). All the time I was running oil changes with Motorcraft 5W20. And last season my motor was putting healthy 376 WHP on the dyno (EU spec cars are detuned to 420 hp from factory).What RPMs are you turning?

I am going to follow the Ford guidelines with the Mach 1 and am even going to get the service done at the Ford dealer. That way there can be no issue of not following the manual if the engine takes a dump.

Right.
I had Ford's Power Pack 2 kit on that car which consisted of a new air intake with open top airbox, a bigger GT350 throttle body and a new tune. The tune they supplied raised the red line to 7250. I did use that red line for a while, but it just didn't do a hell of a lot for lap times vs shifting at 6500-6750 so I mostly used 6750 at most. Fuel consumption was noticeably better using the lower red line, and lap times were within a fraction of a second. I've never dyno'd that car, I just figured it made whatever it made and left it at that. The worst part was that the dealer wouldn't touch it with that kit on it, claimed that their equipment couldn't read the codes with that tune in it. Kinda funny that a Ford dealer wouldn't be able to read a Ford Performance supplied tune, but what do I know?
One other thing to watch for, when I got onto slicks the car was generating enough G force that I got oil pressure drops in the last corner of a right - left - right series of linked corners. It would go down to 15-20 on the last corner, which is definitely not good. So I got a 10 quart Moroso road race pan that was fully baffled installed and that fixed the problem.
