Marvel Mystery Oil

Postby Iron Maiden » Fri Jun 05, 2015 4:46 pm

Sorry I don't have the before pic.
I did not have a bore scope, but could see into the spark plug hole OK with a powerful flashlight.
Now I have the bore scope.
After 4 tanks of gas,
and 15 ounces of Marvel I can see the markings on top of my piston.
Before It was completely covered with crud due to the head gasket was installed backwards,
not by me.
The plugging of the oil return hole caused the left jug to burn lot of oil and
leave a very thick deposit.
After opening the return hole so the oil could return properly, piston top markings are visible.
I am believer.

Thanks Van.

El maravilloso aceite milagroso.
Ain't it a surprising little secret?
I love that stuff since I found it before the last oil change. one tank and a squirt into the oil just 500km before the oil change and no fear to misadjust the valves due to carbon on valves as before. The brown adherences inside the valve covers are gone too.

My only concern is, does it affect the oxigen sensor in new EFI Ural and Kawa W800?
The indication on the bottle says something about high sulfur content, that might bother emission gases.

The holes for to drain the heads seem to be a bit of a head ache in QS, You are the third I heard of this issue. Better a late fix then never.
Well done.
I'll check mine in the next oil change the left side is always full with carbon. Thanks for the tip.

Thanks,
Don't know about EFI issue, mine is a 13 with carbs.
I am using a bit in fuel for all my engines now.
If you find your oil return hole is blocked by the gasket a 5mm sharp bit twisted by
hand very slowly and with drawn several times during the process to clean
the gasket bits works well . I used a t-handle tap holder for the bit.
The gasket is very thin and I don't think a single plunge through would be a problem,
I was just cautious and wanted a clean hole with no gasket bits in the case.

I use this also. Have since the first tank of gas and I am using it in my older bikes 77 and a 79. All of my internal engine parts (that I have had the opportunity to see) seem to be cleaner.

Difficult to get here...as most folks use garages it would seem, and "maintenance" is really much too dirty a word, for morons whose idea of reality is to plug into a computer game and kill zombies....Love Marvel , brilliant stuff, now I have a lead making thing, in the tank and every fill I use about 100 cc of two stroke oil...32k, engine loverly...Trans still clonky....

I'm a user too, but don't forget about good ol Techron. If your in a Chevron station or AutoZone I think, you can get the straight stuff. Works very nice as a cleaner upper!

+1 on the Techron. Very good stuff and sometimes you can find buy one get one free discounts online from the parts stores. The stuff gets high marks at that Bobs the oil guy site and they are wacky about testing these "snake oils".
I run Marvel but it makes my other bikes smoke just a hair, not bad but you can tell when there is some in the tank.

I used MARVEL MYSTERY OIL for years in my Brits, & older engines built for leaded fuels, as a "top oil" to replace the missing lead lubrication. Since ETHANOL has been forced on us, I have changed to using Marine Formula STABIL to counter the affects of the ETHANOL-which it does. I also use regular STABIL to keep my gas from spoiling when I'm not riding a lot. STABIL has just come out with a "360" product I will try next (when my other is all gone)
Since I started using synthetic oils years ago, I have had no concerns about proper lubrication (even without leaded fuels) Synthetic is proven to lubricate best, I have also had NO SLUDGE OR CARBON BUILDUP.
But NOBODY ever made a prettier can than MARVEL MYSTERY OIL.

Istarted using MMO in every tank of gas on every bike I've owned since 1996. If used from the very beginning, somewhere 3 - 5 K later, your valvetrain "breaks in" and becomes sweet as honey - as though your engine is thanking you. My mechanic swears by the stuff - truly the mechanic's friend. I carry it in those syrup bottles you get at Cracker Barrel. Don't be shy about swiping empty ones. I got about 100 of them - they work great.

I have used MMO since 1976 in the gas of all my bikes, just don't over do it, with a 78 BMW R80 on a trip once I must have added too much and oil fouled the spark plugs, glad I had a spare pair already gapped with me. Great stuff.

(off topic - but about cleaning piston top and valves)

Long ago we used to do a thing called "The Italian Valve Job" to de-carbonize the valves and pistons on VW's. Get the engine up to operating temperature, then remove the air intake tubes. Start the engine and rev it up to 1,800rpms-2,000 rpms. Using a spray bottle filled with water, spray a light mist of water into the intake of the carbs. The engine will try to stall when you spray, but keep it running by revving the engine. You'd see black smoke coming out of the mufflers. You only needed to do it a couple of times before no black came out any more.

In a Ural, the carbon may get caught by the cats (if they are still in there) so you won't see as much black smoke. The idea is that the mist turns to steam instantly when it enters the cylinder and cleans the carbon off.
