Those oils have always fascinated me. I also would love some informed perspective on them.I wish he would have spent a little time in the video talking about oils like Mobil's ESP 0/5w-30's that are rated for SP and MB 229.52

Been running delvac esp 5w40 in my 3.7 F150 for the past 3k miles, any concerns for excess wear?
The justification seems to be their use in motorcycles and the alleged comparatively higher levels of ZDDP compared to API SM and later PCMOs. The good old "thousands of motorcycles use this oil and have no problems so it's fine in my XYZ".So is the lure of these oils for those that use them in gas applications the words "heavy duty" and the bigger viscosity numbers 15, 40, etc.?

Last I checked, Rotella has a JASO rating for use in motorcycles.
Agree. Some oils that pass, slip in some MC's. Some oils that aren't tested/don't list work fine in some wet clutches. Just never that simple unfortunately.Insignificant. That standard is really weak. It allows 15% NOACK, has a stupid wide range for wet clutch friction, and a 40 grade can shear 25%, down to a 30 grade and still pass. It makes API SP standards look impressive, and that's saying something.
That could be, but I have never had a JASO MA rated oil slip on a clutch that wasn't already on its way out.Agree. Some oils that pass, slip in some MC's. Some oils that aren't tested/don't list work fine in some wet clutches. Just never that simple unfortunately.
Use a Cat TO-4 oil then. Still a third of the cost of an engine oil with a picture of a motorcycle on the label.
Maybe that, and leftover habits of 15+ years ago when Ritella T6 was the go-to oil for VW EA113 and Subaru engines that diluted a lot. T6 was thick, and at that time, PCMO 5W40 was not as available everywhere as today, especially on the internet.So is the lure of these oils for those that use them in gas applications the words "heavy duty" and the bigger viscosity numbers 15, 40, etc.?
I wish that were true. There are tons of videos in which people push aftermarket parts that are outside of factory spec.Let`s be honest, no YT channel will ever recommend something that`s against manufacturers specification due to possible liability.

Even from FCP Euro, supposed champion of OE quality. I have a serious chip on my shoulder about this one.
At 0:40, dude describes how a certain BMW suspension arm was engineered to bend in a collision so that it won't puncture the fuel tank. Then, in the next breath, he pushes an aftermarket "upgrade" arm specifically because it won't bend in that way.
And that's not even mentioning basically every repair video ever, which uses the manufacturer's instructions as suggestions at best.
Imagine the foam at 15k rpm’sLast I checked, Rotella has a JASO rating for use in motorcycles.
I'm cruising at 1500-1850 rpm with my fingers in my ears screaming "lalalalalala." Foam isn't really a concern in my CK-4 application.Imagine the foam at 15k rpm’s![]()
