This isn't about what the best oil that meets factory spec is or the cheapest.
Let's theorize about the best oil for a given engine is including it's emissions equipment.
Since I own a Gen 2 3.5 Ecoboost (T-GDI) I'm going to use it. It specs a 5W-30, Mechanically shears oil and is a reputed fuel diluter (Gen I was worse).
But honestly it's just the first problem child that comes to mind.
Would the ideal oil look something like a VW 504.00 / 507.00 Oil? A CK-4 oil?
Would it be a 3.5 HTHS for best combination of protection and flow?
Would it be a 2.3 HTHS for increased flow?
Would it be a 4.4 HTHS for increased protection?
I know I have my opinions but I kind of want to see how others would go about it. I'm always willing to look at alternative ways of viewing a problem and it's solution.
