Different oils have different additive packages and what's great for a car may be bad for a motorcycle and vice-versa.
I couldn't find the info at Mobile1, it is there somewhere, but I did find this"
The problem is that what’s great for your camshaft may not be so great for the combustion chamber of your engine. When some of that zinc turns to ash and travels down your exhaust pipe, it ends up in your catalytic converter, and zinc ash is not good for catalytic converters. In fact, enough zinc ash in your catalytic converter can reduce its life.
ZDDP/ZDTP. These same enhancers unfortunately have their downside: The phosphorus in this compound creates carbon buildup in engine bores and valvetrains, and both compounds can also lead to the early demise of catalytic converters.

same Found some more info at Mobile:
Mobil 1 Racing™ 4T 10W‐40 is designed for sport bikes. Most of these bikes have multi-cylinder/multivalve engines and use a common sump, which means the engine oil lubricates the engine, transmission and wet clutch. So unlike Mobil 1 for cars, Mobil 1 Racing 4T 10W‐40 motor oil has no friction modifiers, which could lead to clutch slippage. The motorcycle oil also has more phosphorus/zinc for enhanced wear protection at high engine speeds and high loads. In addition, Mobil 1 Racing 4T 10W‐40 has a high performance dispersant/detergent technology for better high‐temperature performance and engine cleanliness. Mobil 1 Racing 4T 10W‐40 is also offered in a different viscosity grade than Mobil 1 for passenger cars.

Well just added the 15w-50 & fresh k&n oil filter. Quick ride & she seemed to like it. 3.5 qts & at full hot. What I was concerned with was dumping the old oil into a 5 qt container it was only about half full...🤨🤔...used to check the oil diligently & then when I topped it off it would spit all over the right side of the bike so I stopped topping it off.

Mobile technical support is GREAT support based in the USA by people that know the product...call/email them and you will be impressed with the answers.
I emailed them this question:
Product Name: Mobil 1™ 15W-50
Question: I see this isn't JASO certified, is there any potential negative issue in using this oil in motorcycle clutches?
Their answer:
Mobil 1 15W-50 is not recommended in wet clutch applications. This oil would place you at risk of clutch slippage under high load situations such as steep hill climbs, or rapid acceleration.
Thank you for choosing Mobil,

Well, there it is, the people that make the product don't recommend using it for motorcycle clutches; what else is there to say?

Well .. Duh.. M1 is going to recommend their JASO specific m/c oils for any motorcycle use. Why wouldn't they? M1 20w50 V-Twin formula is $10/qt and the 15w50 formula is $25/gallon. That said, would you use M1 20w50 V-Twin oil in your primary? Their bottle says it is intended for that, YET, the 20w50 V-Twin formula is NOT JASO rated. Check out the bottle/specs. Kinda blows that theory.

2. JASO relates to friction properties which are critical in a clutch. Too little friction (energy conserving oil) and your clutch slips like a beach. JASO exists because of wet clutches and car engine oils are not concerned with the performance of motorcycle clutches.
3. API SN is the current high standard for engine oils which is on the 15W50 bottle.
4. Mobil 1 V-Twin 20W-50 is API SJ, which is an engine oil rating for 2001 and older vehicles.
I called Mobile and spoke to a very knowledgeable rep and asked "Why does Mobil 1 V-Twin 20W-50 have a 19 year old API rating? Why not SN?"
The answer was, because it's Mobile's "universal" motorcycle oil; use it in any street bike and you're good to go...the friction properties are set at a point where it's universally acceptable, but can't meet the higher SN or JASO standard.
According to Mobile
15W50 is not recommended for wet clutches because it's friction properties are below optimal for the clutch, but it is fine for the engine and transmission in 3 hole bikes.
20W50 Mobil 1™ V-Twin is a universal motorcycle oil that "does it all" with clutch friction properties that meet the needs of a wide range of bikes.
10W40 and 20W50 Mobil 1 Racing™ 4T is their premium, JASO and SN rated, motorcycle oil with friction properties and additive packages designed to maximize performance.
Mobile makes multiple products to meet the needs of it's customers vehicles, we can all use whatever we want, I'm just sharing what the people that make the oil say so we can make informed decisions on what to put in our bikes.
