Oil Additive

there’s a reason STP oil additive isn’t advertised anymore.

Are you referring to the honey coloured molasses like additive that I used in my '67 CB160 and seized a main bearing? Gave me an engine to learn about how to tear one down and rebuild it!

That was my first thought when I read the post, but @draser said he has used it in 'all my bikes' without problems. I concluded that either he is lucky or there is not enough moly in the additive to be a problem. And I have said several times that I think additives are unnecessary. To each his own.

Now strapping a magnet to the fuel line to boost your mpg is a horse of a different color.

Hey, I tried the magnet long ago on my ‘84 F150 with the 300 straight six. It boosted my mileage from 10 mpg all the way up to 10 mpg! I was blown away by the increase! That was the best money I ever spent on that truck!
 
Engine oil formulations have gotten more sophisticated over the years/decades since our bikes were designed. A lot of them include the additives, detergents, etc, that those mystery oils additives used to provide when engine oils back then didn't. And some ingredients have been removed due to regulations, better engine designs, or otherwise no longer needed.

As was already pointed out, most of those offerings are not for use in a wet clutch. And it even calls into question in my mind if the most popular ones like MMO, or Seafoam are appropriate. All I have ever used was StaBil in the gas, nothing in the oil as it's not worth the risk of clutch failure. Shop carefully.

Hey guys< some additives won't hurt your engines

Aye, but some might hurt your clutch. Since many oils work well in motorcycles straight out of the can, and since there are few if any proven benefits to any given aftermarket additive, why bother? Maybe for imagined benefits?
 
Types of additive packages are viscosity improvers, additional additive package. The thing is that when you add it to the engine the oil changes can get really expensive just with the product cost. The thing with ball bearing engines is that there must be enough drag to rotate the bearings themselves or the elements will not turn and they become flat
The neat thing about Teflon is it becomes toxic when overheated. Typically (not always) oil additives get put in when engine is worn down and added to try to extend it just a leetle bit longer. Which is when the rings and valves are shot.
I think that combustion temp is too hot for Teflon, fire that smokin' engine up in the old garage.
