While I doubt that a single quart over would cause any real issues, I would probably drain an estimated quart from it, then check again. If it is under, add a little at a time and keep checking to get it to the right level. If it is still over, it will be so little that it won't matter.

If you want high ZDDP, you could run any quality CK-4 rated HDEO in 5-40, 10-30, or even 15-40. Those usually have more than 1000 ppm ZDDP, especially if they are not also SN rated. Rotella T4 would come to mind for me.
I watch many Project Farm videos, if for no other reason than the fact that he is entertaining and seems like a great guy. Does that mean that I would base what engine oil I use on his tests? Not likely.
I do find his comparisons of tools and the like to be useful, though. To me, those tests...
Unless it really needs a full syn, T4 will be fine because it's actually a syn blend. It just might be missing some additives because it doesn't have the Triple Protection PLUS that the T5 and T6 variants have because it's missing the PLUS part of that.
Thicker oil is not likely to cause any issues. If anything at all, it might reduce your fuel efficiency by like a few tenths of a mile per gallon. Not enough to even really notice. My Caravan specs 5w-30, but I run 15w-40 HDEO during the warmer months here in WI. Rotella T4. No issues so far. I...
Ive also heard that a synthetic blend oil has to be at least 10% synthetic to be labeled as such, and a full synthetic has to be at least 25% to be labeled as such. I have no idea if this is true, but that is what I understand from online sources. We all know how accurate those are....
The first number only really relates to cold starts. 0w-20 will handle cold temps better than 5w-20, but you will not see this come into play in most areas as even 5w-20 is good down to -25F at least.
Either way, you are perfectly fine running either in your engine. They will both be the same...
