MP: First off< am a skeptic of any of the "as seen on tv crap" that will fix
everything and anything!! Well, MMO worked (so far).
The Short story, I just got a 96 e150 van 4.9. 300 with 47k miles
that sat more than it ran. It had a distinct knocking/pinging/whirling
sound. I have heard these engines are pretty much bullet proof, so I was
pretty sure there wasn't any damage, just probably clogged up from
sitting. I tried a seafoam treatment, rislone, and changed the weight of
the oil twice. Nothing made the noise go away. I saw this stuff at walmart
for $3.00 ish and said WTF. I put 80% in the oil and 15% in the gas(saved
the rest for my lawnmower) and ran 20 miles. Needless to say, I thought I
wasted my money. I called up a backyard mechanic friend of mine who works
for beer(you know the type). He is really good at what he does and can fix
just about anything. Well by the time I got to his shop(total of 37
miles since MMO earlier that morning), the sound was gone. He did enjoy
his 12 pack(going rate) that I still gave him to listen to a perfectly
Don't know how or why, but this stuff worked. Now I know it won't fix a
broken or damaged engine, but for mine with only 47k miles and gently drove
by a grandpa(not me). Heck, for $3 I would give it a shot.
Chris Freeman: You care so much about your engine, but you use a garbage stp filter and
havoline oil. What a tool.
manny6584: wow 10w30 is thin to begin with. does the marvel thin it more?
Kris Erndt: 30 years a fan. This stuff acts like Draino in a clogged sink. it literally
scrubs an old engine clean.
Omar Chisolm: put this stuff down in the spark plug hoes and let sit for 4 hrs. kleans
cylinders out wit live smoke show =D
keg bongHits: I pay 3 .72 $
Shopster Emeritus: let thin out the 5w30 by adding this scammer crap
Royal-T Butler: You put all of in? Not one but two of them?
manny6584: i put that stuff in my gas but nothing goes in my oil but oil. and maybe
some motor koat :)
BRUCE LEE: MMO saved my 2.2 engine when it was 9 years old and the dip stick would
show DRY after an oil change.
I'm also trained for investigative work. . " Marvel is ONLY *_*$3.75___ at
the local General store here in town "........" let's get every........
little drop....OIL IS EXPENSIVE " !!
Steve Congdon: My GMC Sierra with a 5.3 has over 400k. I attribute this to using Marvel
Mystery Oil when I do Oil changes. It still does not burn extra oil between
Chuck B: There`s 86 year old lady I know that used Marvel Mystey oil in her 2
Montgomery Wards riding mowers one at her home in town ,and other at her
lake cottage .She bought them in 1967. still running with alumimum cylnders
on a 5 HP briggs & stratton engines. She used it every time in the fuel.
That`s 46 years !!!
Amazing for a alumimum cylnder engine due to Marvel Mystery oil.
JimmyBean465: Tried this for the first time today, hopefully i get good results....my
engine runs extremely well(go ford). In fact i'm sure at the end of the
world there will be roaches and ford motors lol. But I'm getting into the
mid 200ks for mileage and do a lot of city driving...and i didn't change my
oil for about a year :/
Adam Harr: mmo may work, i do not know, however you wood have served your car better
using a quality oil and filter rather than what you did. there is a reason
that the oil is the cheapest
Jason Reed: I thought the same thing. I figured this might be something to add to your
old oil to flush the engine for a few minutes and then drain it out. The
directions say to add it to your new oil and run 'er for 3000 miles. I
don't think I've found a bad review on the product.
ciscoeric: I just used MMO for the first time. The reason I bought it was I had a
sticky lifter on my GMC for a few days. I had purchased with plans to add
it to my oil change later in the evening. I saw I could also add it to my
gas so while still in the parking lot I added a few ounces of MMO to my
gas. I did not even make it out of the parking lot and the sticky lifter
was gone. It worked for me better then I had expected.
george kuersten: I have seen this gum up an engine that sat for a couple of months. The
stickiest,nastiest varnish ever !
MNmischievious: What a tool
Brendan085: I was trying to find a good example of what I was talking about but I'm not
100% sure where exactly that build up should be. During break in, the
piston or rings seat themselves in a way and I think engines cleaners can
disturb that if used improperly. I think thats why sometimes your not
supposed to use synthetic oils until 5,000 miles or after engine break in
is complete. I have seen Marvel get rid of a noisy ticking noise in an old
Dodge Ram over night with just a small amount in the oil.
Michael Samuels: That marvel is 16oz ,so u need 2 to =1 quart
insanekamkze86: Mmo is 20 percent of engine oil so 5 quarts you would add 4 quarts of oil n
1 mmo if the bottles are pints 16 ounce then u would be right 2 bottles of
mmo to 4 quarts of oil
SocialJustice66: his carfax report should read " used junk oil, junk oil filter, and snake
oil additive, DO NOT BUY THIS VEHICLE"
B Ann: Some of those old ranger motors have been known to go 450.000+ miles with
simple oil changes alone .
ColtDeltaElite10mm: MMO really does work. My '83 Ford ranger has over 366,000 original owner
miles on it and all 6 cylinders still hold compression. My 1978 Cessna 182
loves the MMO. I know a city fire department in San Diego county that has
been using MMO in all of their fire strucks as routine extended engine life
for over 30 years. It just works to Keep engines running cleaner and smooth.
ColtDeltaElite10mm: Brendan085... You are misinformed. The "don't use synthetics prior to 5000
miles" is a myth. Also, MMO has been used BEFORE, DURING and AFTER in air
aspirated airplane engine crank cases to combat both sludge and varnish
build up. Also, it's been used in the fuel to combat lead build up on
valves and carbon build up on spark plugs.
outdoorsman310: hes right
TheCosmicGambler: To anyone who doubts Marvel Mystery Oil add it for the last 500 miles
before your next oil change in a high mileage car that's never had it
before then dissect your oil filter. You'll see why you should only run it
for 500 miles the first time after you get the filter open.
dantheman167: so,,, is your engine cleaner now?
Brendan085: Yes I agree. Its a very thin super lubricant with some good cleaning
properties. Good stuff.
Kyle Whybrew: isnt marvel a detergent ? so wouldn't it suspend all the contaminants into
the oil making it dirtier than normal ? so why are you adding it to your
fresh new clean oil ?
1corxi19mn: thanks for the instruction info for mix ratio.
coolbreez666: no it is an excellent lubricant as well after go 100 miles prior to oil
Chang until the oil stops turning black then start putting it in with the
oil change synthetic oil has cleaners in them anyway.
B Ann: So mixing oil in your gas which 'oil' fouls plugs will help your car run
better ? Do you want to buy a bridge ?
Brendan085: I've been told by experienced mechanics and auto parts countermen where I
have worked that Marvel Oil is more of a cleaner than lubricant. If you
have a noisy motor or a ticking then I would add it maybe about 100 miles
prior to an oil change but I wouldn't leave it in there for an entire
3000+miles. I use Lucas oil for a treatment. I also use Marvel in gas every
now and then.
B Ann: At 6 bucks a quart for marvel its a mystery as to what it really does I'll
stick to basic oil which I've seen engines go 500 thousands with out a drop
of mystery crap .
Alfonso Sun: i'm cavemen...and i do mines lol
safistafaded: I'm going to give his methods the benefit of the doubt, and guess that he
just added an extra 1/2 quart to compensate for the oil filter....right?
coolbreez666: after learning more on the subject i agree with you.
Michael Samuels: yep
Deez Nuttz: If you have a CEL on, just do a MMO treatment through your brake booster
line, about 12 oz will clear up any carbon build up clogging up your
sensors and cat. I had the P0420 code on a Chrysler T&C that has a burning
oil issue and this cleared up the code, passed inspection and light has not
come back on in over 4 weeks. It's better than seafoam.
ColtDeltaElite10mm: Again, my '83 Ford ranger has over 300,000 miles on it, with 1qt MMO + 4qts
of Castrol 10w-30 GTX regular oil. I change the oil about every 6,000 miles
and the truck has had NO ENGINE OVERHAUL. So yeah, MMO works and just use
20% mix with your oil at every oil change. You don't need to do it the
"last 500 Miles" either, that's crap. I use it also on my Honda generators,
chain saw and lawn mowers for years.
LS1Heli: oh god I got one of those 3.4L turds!
Elast3l: he bought his from dollar general im sure...i work there we sell it for $3
where i live and don't carry the 1 quart container only the 1 pint...
movingzachb: Try 5 bucks for that size jug of MM where I live.
Walter Null: Do u really think this stuff works? I have never tried it but when I was in
auto mech class back in my school days my shop teacher called stuff like
this snake oils and said they did nothing! I might have to try it?
TRAILBLAZER02: Just use a good quality motor oil like Pennzoil in the yellow bottle, or
Mobi1. No need for MMO, as those oils have a great additive package as well
as abundant detergents.
Brendan085: Hello. I'm sure it has lubircating properies but if you know anything about
engines, there actually needs to be some "build up " of sorts in the
cylinder to prevent blow by and using a cleaner like Marvel too much can
actually be bad for the engine. Its still a good product you just have to
be careful how you use it.
UnsulliedSpy: The oil filter will catch those contaminants down to about 20 microns, the
rest should be held in suspension by the oil until it is changed next. MMO
is very mild and does not knock stuff loose as quickly as B12 or Sea Foam,
it is best to add it at each oil change so it can do it's thing over the
course of the whole oil change. It is not Snake Oil, anyone who says so has
never used it.
