Does anyone use the Marvel Mystery Oil? If you do, do you get a real tangible result? I've read you can use this to clean the fuel system and clean the engine's components by adding it in the oil. Are these claims real and if so, will the bikes benefit from it?

Unnecessary...IMO.

The product does work as advertised, but it was developed before you were born to combat deficient engine lubricants.

It's simply not necessary with todays synthetic lubes and superior detergents.

+1  It's not necessary even with today's non-synthetic oils.  It's the superior detergents and other stuff they put in that does it.  You don't need to use any additives in your gas, either.

I know plenty of people that have used various additives. None has ever given them an appreciable benefit. I used slick 50 in a car once and the engine died 10,000 miles later. At 80,000. It was a Honda that had it's oil changed every 3000 miles. The car had no issues prior to the slick 50. Never leaked oil. Never was low on oil.

Stay away from additives. They're not necessary and odds are for every one that "works" there are a dozen that cause actual damage.

As the others have said... You don't need it.

But, if you have a rusted bolt/nut... Marvel Mystery oil is a great penetrating oil and you'll have that nut off in no time.

As a side note, back in the day when I was racing RC cars... I would soak all my bearings in the stuff, then one drop on each bearing before the race...
Track records were mine at more then a few tracks. Great penetrating 5wt oil.

I typically only use it to squirt down plug holes of motors that haven't been started in a forever.




In other news, Slick 50 is the *only* additive recognized by the Automotive Society of Engineers as doing something positive for your motor.


(This was some time ago, mind you)

seafoam!

Good stuff for other applications, but not needed for the oil, or gas IMO

Good gas and changing fuel filters should keep the fuel system clean.

Most modern oils are well suited with their additive packages

Man I used that stuff in the 80's! it worked back then, probably unnecessary now.
I saw some one post "seafoam" I used that on my LS1 and it worked like a charm.

My mom has always used that stuff in her gas until recently. She bought a newer car that was fuel injected and after a short time it ended up poisoning the o2 sensor. Killing her mileage. If I remember right, and I may be wrong but, it does contain trace amounts of lead or something like that to cause this problem. I don't think its at all necessary to use unless like mentioned before, a penetrating oil or for an older engine that has sat for a while, or stubborn nuts/bolts. Also like I said probably not good to use in a fuel injected bike. At least not in large quantities.
