Most of our customers add Marvel Mystery Oil when they change their oil and leave it in until the next oil change. They do this at every oil change. Since you have a 4 quart system, yes, you can use 16 ounces of Marvel Mystery Oil and 3.5 quarts of your regular motor oil.
Not trying to rain on anyone’s parade; however, automobile manufacturers and/or the oil companies state that oil additives are not recommended or required in modern automobiles or oils. They state maintaining correct oil levels and change intervals are the only necessities to engine wear and longevity, as far as oil related wear is concerned?? I do know that gas is not anything like the gas of old and additives there seem appropriate; however, oil formulations seem to have been ever improving and adding “stuff” to it seems contradictory; at least until this latest removal of zinc? After all, the oil refining process seems geared to “refining” stuff out, not putting it back in?
My skeptical nature makes me wonder if all the “additive” addiction is simply more a function of the bottom line to the additive manufacturer than any realized benefit to the consumer? Fuel system cleaners exempted necessarily. As an example, CD-2, or other lead substitute is required in engines not designed for unleaded gas. I do not know of any true benefit of an oil additive, until the elimination of zinc, in modern oil?
I would like someone to make the case for oil additives without the “it just feels smoother, quieter, more responsive,” applesauce that seems to merely justify their having poured an additional $5-$15 worth of ‘stuff’ into their already expensive oil change! Make me a believer. . .
I somewhat agree with this poster regarding using it in the oil. Unless you’re using it to clean something out that has not been properly maintained, there is no need for MMO in the crankcase, and certainly not keeping it in for an entire oil change interval. You can’t beat a good synthetic with MMO, especially for running at least a 10k OCI, which is what any decent synthetic should be able to do.
As far as in the tank, I use it every oil change, but my oil changes run from 10-20k. I also use it as a stabilizer.
I am sorry to rain on your parade, but even if you use a quality synthetic oil MMO will help. Motor oil’s do 2 things, cool parts and lubricate parts. Motor oil’s do not clean as well as MMO, and I will give you some examples.
My Mom has a 1998 Chevrolet Monte Carlo that has 108,000 miles on it, she insists that I change the oil every 3000 miles. The valvetrain looks spotless when I pop the oil cap off to take a look inside. This past summer I added about 8 ounces of MMO 1000 miles before her OCI, when I changed the oil 1000 miles later it came out very dark. I then added 4 quarts of oil and 16 ounces of MMO and took the car for a drive, it was so much more responsive. 1000 miles into her OCI the oil level was down about 8 ounces, my thinking is MMO cleaned up some stuff in the ring packs, I added some oil and I checked the level 1000 miles later and it was perfect. This car has seen Mobil 1 5W-30 after the 1st 3000 miles on this car.
I noticed the same thing with MMO when I added it to my Marauder at 30,000 miles, this car has been using Amsoil 0W-20.
I also put some MMO in my snowblower that has only seen Amsoil 100% Synthetic 5W-30 and the oil came out very dark and the engine seems to like MMO in the oil.
My Dad has a Cub Cadet Tractor and at 25 hours I changed the oil, I added about 3 ounces of MMO to the oil and when I went to change it at 50 hours the oil came out darker, this machine has only seen Pennzoil Platinum 10W-30.
From my observations even the best synthetic oil will not prevent deposits from building up, the use of MMO will keep an engine cleaner than synthetic oil by itself, and it will attack any deposits that synthetic oil fails to get too. I used to believe that all you really needed was a good synthetic oil, but my mind has been changed because every engine I have added MMO to has cleaned it out and made it run better, I am a believer in MMO, if you don’t believe me give it a try.
I’ve used MMO in my oil a long time ago, can’t say it made a difference. Since I’ve had new vehicles, I use top quality synthetics, and don’t feel the need to clean things out, they never get dirty. Can’t say I’ve noticed a difference when I put it in the gas, but I do every once in a while, just for kicks. I use it as a Stabilizer mostly.
I’m glad it works so well for you guys, and I’m not going to say anything else to extinguish your enthusiasm for this product and all you think it does for you. Enjoy.
Boy, there’s a lot a parades being rained on in this thread. And, a lot of snake oil type sales for MMO lately. I don’t believe that an oil’s color after 1000 miles is always a good indicator of it’s detergent value. Also, I know for a fact that Amsoil and Royal Purple do a excellent job of cleaning an engine. I’m an avid user of MMO, but not to “instantly” increase my compression or run for longer periods of time than Marvel itself has tested. I’ll keep running my top tier synthetic oils without additives for 8 or 9 months and then add some MMO and run until the 12 months is up. I always run it in the fuel and always in my 2 stroke engines. The best synthetic oils don’t need additives when new, even though I consider MMO as one of the best additives. After they have run 6000+ miles, then the added boost can help. In my opinion.
Ok, Im 63 yrs young, and have had many cars. I have used mmo off and on. It did correct rough idle at times when I used it. In an old truck it also fix rough idling and eased start ups when cold. I have used Lucas as well and have gotten the same results..At the moment I have a 2002 Dodge Ram Van, 318 v8 with 208,000 miles on it. I do add MMO to the gas only and it has corrected rough idle, but so will Lucas fuel additive. I run Mobil One 10w30, but I do not add any additives because I called Mobil and they said not to. I know, I know, some of u think differently on that. I have seen engines on other sites that were taken apart and they were clean using Mobil ONE only.....I will keep using MMO in my gas and Lucas fuel additive. Both are working for me. AS a kid someone gave me some MMO to get a lawnmower running and it did the trick. Dirty carb on that one. So its working for me and we sometimes get lucky and the right cleaner does a good job. But sometimes I think we see what we want to see and our brain thinks there is an improvement when in reality there is not. Like those blind studies where one group gets the real medicine and the other a placebo( fake meds). The folks with the fake meds felt good to. Well its a thought, but I think we are keeping a lot of companies in business when we dont have to.. But I can get addicted to stuff like everyone else. Me, I read all i can find on Oils and an open to the next Snake Oil, its fun to read about stuff, guess its a man thing.
PS:: I’m a Good Will Junkie, love rummaging thru that stuff,,,,,,,,,,,I need mys meds. lol
In an engine that is in good mechanical condition MMO is probably unneccessary in most, BUT NOT ALL cases. In engines that are prone to valve sticking such as for example some Continental light aircraft engines and certain Range Rover V8s MMO has been shown to free up valve stem deposits that cause valves to improperly seat or “stick”. Do a web search or google groups search on Marvel Mystery oil for aircraft engines. I have a Royal Enfield motorcycle which is in good mechanical condition , yet is known for rapid carbon buildup and occasional sticking valve problems. MMO has solved the problem. MMO keeps engines clean and free of deposits and is recommended in those engines that are prone to that condition. In older engines it positively is a benefit in most cases. It cleaned out my barn resurrected 1948 Buick 8 that had sludge and carbon buildup from years of neglect in the past. It freed up sticking rings on two cylinders and restored compression. I now run it with the crankcase with the 15-40 at a ratio of 15 percent at all times. If you saw the bottom of the bypass oil filter housing of the Buick, with all the sludge and carbon granules it removed from the engine you would be a believer.
I run MMO in my crankcase (16oz) in my power steering fluid (1 oz) in my transmission (4 oz) in my front end (4 oz) rear end (4 oz) in my gas every other fill-up (16 oz). I have never tried it in my radiator.
Recently, I have used it in my oatmeal (1 oz) in my wife’s douchebag (3 oz) and as a laundry detergent. I know a few people who use MMO as personal lubricant, although I have never tried this.
Does anyone know, can you use MMO in place of Visine eye drops??? thanks

Try it and report back............
I have tried it as a elixor topping on white castle hamburgers. Independent laboratory tests prove it substantially increases the laxative effect of the slider by increasing the lubricity on the inside walls of the intestines. Helps promote natiural intestinal health with increased vigor, vitality. and long life.
Interesting post. I’ve been using MMO on and off for years along with other products (Red Line Si-1, Auto-Rx, Lube Control LC20/FP60). I find MMO giving the quickest response when used in the fuel system- an almost immediate smoothing of the engine.
I also add it to my crankcase about 500 miles before the oil change. The first time I tried this, the oil was A LOT more black when I did the regular oil change. Same thing with my Dad’s (RIP) Odyssey (he also did his own changes). He too noticed how much darker his oil came out.
I’d guess that the MMO has a capacity to suspend the dirt particles in the oil which allows them to flush out rather than stick to where ever they were prior to adding the MMO.
Im using 16 oz of MMO with 4 1/2 qts of Rotella 5w40 in my 318 , Dodge van with 228k miles on it. It does not use any oil between changes and I use an OCI of 8k to 10k miles. I can only get 16 mpg to the gallon and thats good for a one ton ram van. I carry freight in it most of the time. The rotella is a full synthetic oil and I will continue to use it and the MMO too.
That is how I am using it now too. I add a pint about 500 or 600 miles before I change my oil. MMO cleans out the engine very well and the oil is really dark when it drains out. Engine runs great too. I still add 2 to 2.5 ounces at every fuel fill and MMO really helps my truck run a lot better and get a little better MPG.
First post on this forum for me. All I can say is, I’m a new MMO user and have been dumping it into gas and crankcase on everything I own that runs on petroleum distillates, from the lawnmower to my Infiniti, for about a year now. Without tearing apart an engine (which I will definitely not be doing) there is no way to scientifically tell if it is helping anything in ANY way.
HOWEVER, even if all it does is provide a placebo effect for the owner, for $12/gallon that is cheap!! If pouring it into my POS 96 Windstar or junktastic 1980-something Briggs& Stratton lawnmower makes me feel better about how they run- and keep me from feeling like I need to replace them with the latest and greatest, then it is the cheapest additive $ can buy. And not for nothing- but both of those relics run like new… is it the MMO? Who knows, but I feel like I’m doing everything I can to not have to shell out $25k for a new van and $600 for a new mower.
I always use 20%-25% of MMO in every oil change with every car we have. We use 0w-40 and 15w-40 Mobil 1 full synthetic and MMO with Mobil filter. We go 10,000 miles between oil changes. Also, we use MMO with every other gasoline fill-up.
2002 Infiniti-140,000 miles (Family Car)
1996 Nissan-190,000 miles (Our work horse and daily driver)
1993 Chevy truck 1500-180,000 miles ( On light duty and reserve)
+1.
ALWAYS use a good synthetic engine oil (Mobil 1). I tend to err on the more conservative side and add just about 10-15% of MMO toward the end of the oil life (at ~8,000 miles for me).
