Here is the VOA for 5w40 CJ-4/SM in on the left, while the CK-4 is on the right...i kinda expected the 15w40 to be much more potent.

Thank you for the VOA. I expect this oil to be more shear stable than the 5W-40 version, which is a particularly good benefit in shared sump motorcycles.

Thanks for posting this. Weak add pack, surprisingly.

Thanks for the VOAs. Great job, really appreciate the work you put into this. Without question, to me anyway. The T6 15/40 looks great!
Considering it for my boat.

Thanks for doing this.

RT6 15W-40 is basically the exact same thing as RT6 5W-40, it will just be a bit thicker in the cold, and more shear-resistant.

For a summertime hot-rod or bike, it would be just about perfect.

I love how B-S didn't even know what it was! LOL!

Thank you for the VOA. I’m inclined to agree on the add pack, weak-sauce. Is it just me or does the T5 15w40 look stronger?

T5

You can not tell which is a better oil by looking at the limited results of a VOA.
Either way 15/40 rules over a 5/40 if you dont need extreme cold weather performance.
I am partial to conventional and semi synthetics but nothing against full synthetic either, they all serve a purpose and I am for sure interested in the T6 for my boat.
I use Chevron conventional in my car/truck.

Degreaser thanks for the side by side makes life easier. Why is moly the weak point for the T5?

Alarmguy I agree w/ you & wasn't necessarily stating one being more superior than the other, It just seems the add pack in the T6 seems not as strong as in the T5, kinda of shocked me how “meh” it was IMO, I use T5 in all my diesels & generators. For my motorcycles i use Mystik 15w50, That being said I just did my last oil change in my Cummins 5.0L (Nissan Titan XD) w/ the T6 15w-40. As you can see I agree with you on 15w40’s being superior.
