Oh boy, where is my popcorn???
I thought the exact same thing. No mention of why this guy is not comparing IDENTICAL oils across different weights. Different add packs for starters. Mobil 1 ESP as an example, has one of the best add packs out there and is actually rated for diesel engines.
Then no mention of the fact DI engines are harder on oil over time due to fuel dilution. That 0W20 is sheared down to closer to an 0W10 by the time you reach the OCI of 5000 miles, so what about all those that go past that?
Factory fill for the engines like the LT2 Vette is 0W40, and granted it's making 100 more hp stock, but clearances are the same.
Not that long ago it was 5W30, so there's that.
We can thank CARB and the EPA for all this BS in the efforts to eek out another mpg or two, and decrease reliability in the process.
On another note, the JD Power awards mentioned in this video are a joke that write themselves.
I remember when Wards had the 6.0 Powerstroke diesel as one of the top 10 engines for 2003, THE same year they were introduced(well technically 2003.5) in the Super Duty, and what a hoot that ended up being. I know Ford mastertechs that ended up quitting their jobs due to that whole debacle.
Having worked on my share of those and bullet proofed more than I care to remember, the cheapest mod was going to a good 5W40 synthetic diesel rated oil.
They remind me in some ways of these L83's thru the current models, once they have all the crap they don't need removed they are a great engine.
