I mean it doesn’t matter until it thins out too much and you scuff or seize a bearing. Lake comes from a racing background where that kinda failure is going to hit you fast and hard if the oil gets too thin, and some of us do track our cars.Why does viscosity retention matter? Unless viscosity and HTHS drop significantly, does any of this matter? Yes sure, I prefer a 1% loss compared to a 7% loss.
It’s a fair point that the margin for error for the vast majority of people daily driving is going to be a lot more generous, and some of these differences are splitting hairs. That goes for a lot of oil specs. PAOs outclass Group 3 in a pile of ways but I’ve found off the shelf Group 3 oils hold up shockingly well daily driven in my mustang over long drain intervals. Why spend a lot more money on what’s going to be a marginal improvement at best?
They did a legit and interesting test in the video, especially with the eight custom blended base oils with different VII. Sure there’s follow ups I’d love to see done, but what the tested and the methodology all seemed pretty above board. What part do you think was dishonest?On a related side note, it seems that we have sold our souls to YouTube views/subs (and money). We’re busy supporting an algorithm that doesn’t reflect honesty and integrity
