Why MMO

I have owned about six or seven antique and exotic aircraft since 1988. My first aircraft mechanic told me to use Marvel Oil in the gas and the airplane would just plain run better and have better lubrication. I used it on all my airplane engines, until one day in 1998 I bought an antique plane in Michigan. The owner said "No, don't use any of that stuff in this engine!" I didn't want to change anything during a 2000 mile ferry flight back home, so it was the first time I ever didn't use Marvel Oil. Sure enough, a couple of days later flying towards home in extreme high temperatures through Texas, that engine stuck an exhaust valve because of carbon buildup and poor valve stem lubrication.

I lost a whole day waiting around for a mechanic to free up the valve. I asked this mechanic how they keep their planes running in the 115 degree Texas heat, and he said to me that they put a little Marvel Oil in the gas! I could have strangled that damn guy in Michigan... and it's the last time I ever failed to run Marvel Oil in an airplane engine. Some things just work.

My wife and I have three cars, a '01 Jeep Wrangler, '05 Chevy Colorado & a '06 Jeep Liberty. The Wrangler has had a valve tick since new, the dealership said there was nothing they could do about it. I started putting Marvel in the crankcase & gas and the tick went away! I recently fogged the throttle body in all three vehicles with Marvel as well as putting it in the gas & oil, what a difference in performance & fuel economy. I also used it in the automatic transmissions of all three vehicles, they shift so smooth you can hardly feel them shift!

We also collect antique tractors & hit and miss engines and use MMO on those too. My Dad is also a big fan of MMO and has been using it since the early 60's, with his father using it before him. We've used Marvel in everything we've owned from firearms to ATV's to automobiles. We love your product and would love MMO stickers for our vehicles, so we could spread the word about MMO!!

Wow, where do I start? I have used MMO for around 40 years now. Since I got my first car at 16. I honestly don't remember who told me about it, but I remember adding it to the gasoline and engine oil in my Triumph TR-3 and every car since in the last 40 years. Oh, and my model airplane and car engines. I use MMO as an "after run oil" and it prevents bearings from rusting due to the hygroscopic effect of nitro methane and methanol. As well as generally preserving my model motors. I have some motors that have been stored in a plastic bag for 25+ years with MMO as a coating and they still are rust free and turn over like the day I put them away.

But to this day, after every flying session or engine tuning session I add a few drops of MMO and bump the motor over and I know it is protected. I am a retired mechanic and I used to work for the MTA in Los Angeles. When we had a diesel engine bus get sticking injectors, I would hook up a quart of MMO straight to the injector pump and those sticking injectors would clean free and the bus was back on the street in a jiffy! Marvel Mystery Oil is a super product. I believe in it totally and am thankful it has been available to all of us gear heads for so long. Best regards!

So I am a new-comer to the MMO product. I have raced for about 7 years doing Superbike racing. My first day after purchasing a 2006 Yamaha R1 I started immediately using MMO in the fuel. And after my first oil change switching over to MMO 1 quart with some Full synthetic oil. Got to break the clutch in! My bike has ran exceptionally well for the time owned. I took the bike to the Race tech, they were curious about the outcome of MMO and asked to break the engine all the way down.

And friends, let it be proof, after 2 years of running MMO in the fuel and Oil, the mechanics were flabbergasted. They couldn't complement about the engine so much, they were "marveled" at the fact that the engine was almost, well brand new looking. I will be due up for a valve adjustment/change. Those are done at 26,500 Miles. The mechanic decided to just go ahead and check all the valve clearances, and well, they are all still factory spec and I mean off by maybe 1mm. WooHoo! So I couldn't say it enough, but I also couldn't advertise MMO enough as well to friends, famlies, and strangers. This is definitely some out of this world stuff, and works wonders let alone in high performance motorcycles. Thanks a lot Team Marvel! Your the best!

5 years ago I purchased a 1999 Harley-Davidson FXDX with Harleys new twin cam engine. This bike was in storage a lot and was not ridden much - a average of only 900 miles a season! Needless to say it ran kinda rough, didn't start all that well sometimes, power seemed lacking. In other words the bike was full of cobwebs!! The only thing I did to the motor was clean the K&N;air Filter, and put in a new set of Harley gold spark plugs. I started using MMO at first in every other tank, after the first few hundred miles I could really tell that the carb got cleaned out, because I had to make an adjustment to the idle speed. And the motor started much better. Now after riding well over 15,000 miles this bike runs better than new, I have checked the plugs and put them right back in because they still look new - just checked the gap.

The bike starts always on the first crank - even out of 4 1/2 month winter storage!! This spring I cleaned my air filter again and checked over the carb and it is clean and shiny with no traces of rust or gum/varnish build up. I use MMO in every 3rd tank now and always will, it seems to make a difference. It certainly is a mystery what's in it and what it does!!! KEEPS MOTORS CLEAN AND RUNNING LIKE NEW. And yes, I use it in my two other cars occasionally also. And in my many small motors, which are 40 year old chain saws, lawn mowers, weed wackers, generators, snow blowers, air compressors, tiller, leave blowers/mulchers.

I first learned about MMO from a boating friend almost 20 years ago and began using it in my twin-diesel trawler. Immediately, I noticed that during run up after prolonged idling, smoke was reduced by at least half. But more important, fuel efficiency in terms of miles per gallon increased by a consistent 11 percent. Since then, I have used it in four SUV's I've owned and more recently have begun to use it in all my outdoor power equipment including lawnmowers, trimmer, blower and chain saw. In the meantime I learned commercial fishermen use it in their boats down on the Gulf Coast. Also, I have heard several legendary stories about how MMO helped keep military equipment operating in the South Pacific during WW II and pilot stories about their great experiences of using MMO in their planes.

In short, this is a great product and I recommend it to everyone without any reservations whatsoever. Finally, I am very pleased the new owners of the company elected to retain the same distinctive design on the MMO containers. In fact, I have two of the older metal MMO cans on display in my office. I hope to continue using MMO for as long as I have a steering wheel in my hand. And for the sake of everyone else, I hope it's always available to them, too.

I have no idea what the you genius's make this "mystery oil" with but you are GODS to me. I have a 98 Pontiac Trans Am. I just bought the car about 1 month ago. During this time I have changed the Spark plugs in it and that's it. The car only had 55000 miles when I bought it and had been garage kept. The only time it was driven was in the summer. Well, I changed the plugs and upgraded the fuel type to Plus. This is when my problem started. I did a diagnostic test on it and it said that there was a #7 misfire. Well, I knew the plugs were good, so I checked the plug wires and the coil pack. Both of those checked out. My last option was a fuel injector.

I knew that's what it had to be but no one else wanted to believe me. I reset the computer hoping that maybe it was a computer problem and that it would just go away. Wrong. The service engine light stayed off for one day and then it was right back on. The motor started to jump and shake again exactly like it had done before. This time I went with my gut instinct and went out to look for a fuel injector cleaner. My uncle told me about this product and said that he trusted it with his life. This had me excited because this man isn't commited to anything unless he is certain that it works. Sure enough I went up to Autozone, bought a 1 quart bottle, and then dumped half of it in my fuel tank.

My dad was a mechanic for 40 years. That means he started in the 30's working on Chevy's at the local dealership in Corsicana, Texas. I can remember distinctly the smell and the color of Marvel Mystery Oil that he used for upper cylinder lubrication and to help burn out the carbon on the valves and anything in the combustion chamber. He would pour the oil directly in the carburetor until he killed the car or whatever engine he was working on.

I thought it was cool. Well, guess what? Like father, like son. Although I don't flood the engine with the oil like he did, and I don't make my living turning wrenches anymore, I do use the oil in the gas tank and the crankcase. It is amazing how much difference the internal engine parts show on a teardown. There is very little sludge or carbon build up like you normally see, for instance in the head area. Like dad's cars, we never had a problem with a valve burning, ring sticking or engine seize.

If published, this is my second testimonial here. But this it totally unrelated to my previous experience. I am in the Coast Guard Auxiliary. One of our officers obtained a boat from a family member which had sat for many years. After normal tune-up, etc. the boat was approved for use by Coast Guard. On its maiden voyage, (which was a safety patrol) the boat would not idle, ran rich, smoked, dyed numerous times, etc. I and crew thought we would need a tow to shore. To be a Coast Guard member, and have your Coast Guard patrol boat towed in is almost unthinkable.

On a hunch, (based on my previous experience in first testimonial), I obtained a quart of MMO and poured the entire quart into 20 gallon fuel tank of this boat. After a run up the lake at 3/4 throttle, I could smell the MMO being burned in exhaust fumes. The boat began running better and better. After an hour, it ran like a new boat. It idled perfectly at 900RPM's. It had no hesitation, and stopped missing and dying. We assume the MMO cleaned the boat's carburetor of varnish and gunk collected from boat sitting for a long time. Thank You MMO for saving the Coast Guard from being towed in!
