Marvel Mystery Oil MM14R 1 Gallon

I've used this stuff to get seized engines turning again. Ive had trouble finding it but I'm glad to have found it here. I remember buying 25$ gallon jugs of this stuff at my local Walmart. Ah how prices have changed. Overall good product, decent price.

Started adding this to my gas and oil changes because a mechanic friend of mine recommended it. I noticed better acceleration and lower rpm’s resulting in a smoother ride.

I have a lot of 2 stocks toys, 4 wheelers and hot rods; I play in the Mahajan Desert. Keeping my engines clean is a necessity if I want to keep them going. My Dad turned me onto Marvel when I was a kid, 40 years ago. I only put two things in my gas and oil and Marvel is one. I have used other stuff and check out their properties and they don’t cut it, not even close. Marvel does what it says it does, it’s a detergent that works fantastic in gas and oil and lovers oil viscosity. I use it just before an oil change to get all the dirt out and put it in the gas to keep the junk that builds up in garbage gas we use in CA. If I am going into cold weather States like MN in winter I use it to lower the viscosity of 30 weight oil to keep my lifters from knocking and make sure the oil is pumping without having to high oil pressure. I have blown oil filters off, using 30 weight in cold weather, it’s not good! It turns 30 weight into 10 weight when you do it right. Good stuff and I don’t indorse anything.

I use this oil in all my small machinery around the acreage.Especially as an engine fuel additive.Marvel Mystery Oil and SeaFoam work well for an over winter stabilizer too.I use a lot so the gallon jug comes in handy.

Great stuff! Been around for forever seems like. I have used it as a fuel additive in cars/trucks as old as the 60's all the way up to 2014. I haven't found that used that way that it messes up O2 sensors or catalytic converters at least in my experience. It does help clean the fuel injectors and the combustion chambers and intake valves. In the older vehicles.. 30 years old or older.. It can be used not only as a gas additive but in a pinch it can be used as tranny fluid [in dextron fluid trannys] and power steering fluid. I also use it as a air tool oil.With all the uses it is very economical

Product is great but it came damaged and it took weeks to get a credit resolved

ALSO I love the fact you put the gallons in a zip lock bag. Thank you!!Diesel engine problems in my Ford Econoline E-350 van cured by Marvel Mystery OilI was spending an extra $20 per tank on other additives. If I failed my engine light would come on unless I stayed on top of it at all times. Last time I had my fuel injectors & system cleaned it cost me $1,700+.Then I watched 2 educational videos about Marvelous Mystery Oil.YOUTUBE - Lucas Fuel Treatment vs. Marvel Mystery Oil BY DixonYOUTUBE - Seafoam vs Marvel Mystery Oil! The Ultimate Showdown! BY Project FarmOut of desperation I added 32 ounces and my engine light went off & all problems. Fuel mileage greatly increased too. Now i'm cutting back to 4oz per 10 gallons fuel.UPDATE ..... after a 2 months & catching my mechanic lying about my turbo needing replacement it is hard to ascertain what made my engine go bad. But in any case my Ford 6.0 Diesel engine has piston and fuel injection codes signaling the engine is bad. So, as it turns out me adding more of the Marvel Mystery Oil may have damaged my rings & seals. Too bad it costs too much to figure that out.

I have an older Mitsubishi SUV. MMO serves a dual use; fuel and oil. Some older vehicles require upper cylinder lubrication. This can be obtained by adding MMO to your fuel. MMO helps reduce carbon in the upper cylinder and which reduces friction, i.e. pistons.Also, MMO can be used in the oil. Once in the crankcase, it can reduce friction in cleaning and can reduce the amount of carbon. MMO acts as an antioxidant. Think of your oil as the blood that runs, via our veins. It is the life line of your vehicle. Oil lubricates and cools the engine, reducing friction.Engines are fined tuned machines, which produce power. These kinetic machines requires every part to move in synergy with other mechanical parts.A reduction in friction will increase the efficiency of your engine. This could increase miles per gallon. Combustion engines produce a lot of friction. Any reduction in friction equals a reduction in $$$$$$. Consult your mechanic specialist prior to use.
