Seems like he`s gambling with liability then
Evidently it's not much of a gamble. That video's been up for 4 years.
And, again, it's far from unique. People recommend sketchy non-factory stuff on YouTube all the time. Like every single aftermarket parts vendor that posts on YouTube (not factory parts by definition). And most "here's how to fix this" videos (non-factory parts AND procedures).
Which is why this...
...while it would be nice, is unfortunately not true.
You mean like here on BITOG? Folks recommend things that go against the OEM's recommendations all the time.
Wow. I can use the word "science" two times in 15 minutes.
I’ve tried the rotella in 3 separate road going motorcycles and shifts were terrible, everytime. Motorcycle specific oils are there for a reason, and not expensive!
A wise man once told me “Rotella is a jack of all trades, master of none”
I suppose, if you can't discern what "against" means. For one thing, as you note they are recommendations so a person is free to recommend something else based on what should be sound reasoning.
For example, if a manufacturer recommends a -20 grade low-SAPS oil for a vehicle, I would not consider it "against" to recommend a -30 grade low-SAPS oil. On the other hand if a person recommends a high-SAPS oil that would be "against". Similarly if the manufacturer recommends a -40 grade and the person is advocating the use of a -20 grade then that would definitely be "against".
I guess I distinguish between what is a significantly different suggestion that would have the potential to adversely affect engine operation or one that is in some ways an improvement. Here in this section of the forum a recommendation of a spark engine oil without a proper diesel license or approval would also constitute "against".

I feel you. Really any departure from what is specifically called for is
But I agree with this aswell. Sometimes an oil goes in a 30 and is dumoed sheared, and thinned to a 20, or so is my understanding. If the goal is to maintain a 20, then maybe a 30 is the way to go from the start. As witness to the countless who use 5w30 instead of 0w20, in Toyota engines for example.
FM is a powerful factor in the Rotella!
Hushup commie!
I would have used a stronger word but I think they are out to get me.
I seen the lights though the trees last night out in the forest.
They aren't licensed to SP, they are just "meets engine test requirements."
That distinction matters to some. Not so much to me, but I'd be curious why a huge company like M1 wouldn't just go ahead and get the formal SP license.
I don't think comparing a CH-4 or CI-4(+) oil in place of an SM oil to a CK4 in place of SP is quite apples to apples.
LSPI is obvious a non issue for a diesel engine and no diesel spec would ever test against it.
If the gas engine is old enough, I'd consider a dual-rated (not a Cx-only API rating) oil to be just fine.
But an CK4/CJ4-only rated oil in a newer car that calls for SN or SP I would strongly recommend against. Especially if TGDI.
CK4 oils are highly additized, but it's the wrong additives. The add packs have shifted more and more towards soot management (thank you EGR) and towards aftertreatment health (low SAPS). Neither of these areas of emphasis are appropriate to a modern gasoline engine without aftertreatment.
And given the zero sum nature of add packs, it seems to me that a modern CK4 rated oil MUST be less capable in gasoline engines because it's majoring on the minors and minoring on the majors.
Modern oils are more specialized than ever because they have to be to meet the more stringent demands.
Well said, IMO.
Not the intended market for the product, or it would compromise the approvals it does have.
Delvac 10w30 and 15w40 are both SP licensed.
If HDEOs cause elevated wear in gasoline engines, they would also elevate wear in Diesel engines, but we are not seeing that.
How much information can one extract from a UOA following a few dyno pulls on a 70 year old engine design?
Last I checked the ESP 5w30 was SP. The ESP 0w30 isn’t because phosphorus is over the 800 ppm limit. I’m sure someone will correct me if it’s changed.
As far as I can tell, this is correct.
I think that’s right, I only checked the 0w.
The video addresses this, as does my summary of it.
