Marvel Mystery Oil(R) lubricates the entire fuel system-fuel pumps, fuel injectors or carburetors and the top portion of the cylinders. These are areas, that by design, motor oil does not reach. Using Marvel Mystery Oil in your fuel extends the life of these vital components by providing them with lubrication that fuel alone does not provide. Marvel reduces and prevents varnish and gum build-up, two key contributors to robbing engine performance. When you shut off your engine, a miniscule drop of fuel is left at the tip of the fuel injectors or carburetor jets. This miniscule drop off of fuel then solidifies into a varnish type residue. Over time, the accumulated varnish blocks the openings of the injectors or jets, contributing to lower performance and fuel economy and shorter life of these components.

Valve Cleaning

Helps maintain cleanliness and smooth operation.

Provides lubrication for valve stems and upper cylinders.

Improves engine performance and gas mileage in aged cars.

[This review was collected as part of a promotion.] This oil is a nice light oil and we use it for all things that need oiling around the house not just air guns. Examples are the furnace oil points, sewing machine, hair clipper, hinges, locks and more!

More than a just for air guns.

Keeps my engine from knocking %26 running smoothly. I also like the better gas mileage. I keep two quart bottles that I refill from the gallon jug. The quarts fit in my rear car door near the gas tank lid. On long trips, I need to use 2 quarts for 8 gas tank fills.

Smooth running engine %26 better gas mileage

I have not used the product yet.  I am hopeful it will help me get my project truck running.  I plan to pour this into each of the cylinders and let stand for a while before trying to rotate the engine.

hoping it works

I have been using marvel mystery oil since I was a little kid. I'm 65 now and trust this product 100%. I use a ounce or so in my fuel and it keeps the carbon off the piston and valves. It works super, and does a better job than anything else I've seen in comparison!! You can use it in your oil as well and keeps your engine clean.

Marvel Mystery oil fuel treatment

I've used MMO in my airplanes for years. Many aircraft engines that are lower compression can use auto fuel if it's ethanol free. Adding MMO at the recommended rate replaces the lubrication lost from being lead free. I've never had any valve issues and I've been doing this for thousands of hours over close to 50 years.

Been using MMO for many years

This item has been dis-continued at our local store.    Some auto parts stores have this size in stock but their price is much higher than Wal Mart.  I found that I can get this from Wal Mart online with free shipping which is worth the time and effort!

Marvel Mystery Oil one gallon

I love this stuff. I had a flight instructor who used to use it in his piston aircraft engines, and I started using it in my GMC Jimmy. At 250,000 miles, I had replaced just about everything...except the engine. I can't argue with success. My Nissan Xterra enjoys the same menu mixed in with every fill-up.

An oil that works in mysterious ways.

My old 20 year old car was using a qt of oil every 1k miles, thought oil rings clogged up,added 12 ounces to oil 500 miles before oil change, now its at almost 1500 miles before I have to add a quart. I plan on doing the same thing 500 miles before every other oil change.  I also started adding 6 ounces to gas every other fill up and car runs so much smoothly, and gets almost 2 more mpg on the highway driving. I also add 6 ounces to 5 gallon gas can for use in lawn mower and snow blower as a cleaner and stabilizer.

Can't go wrong

I used this product for many years. I put InThe oil and the gas because it has proven to me that it makes my equipment last for many years. We have a lot of property and a lot of equipment to take care of an a lot of hours of use. MMO has kept them working all these years

Great produce

Marvel Mystery Oil is as useful now as when it was originally introduced. This fuel/oil treatment is as good as it gets. It improves my gas mileage while drastically reducing the wear on my engine components. With a better seal during combustion not only do I have more power and greater mileage, my oil changes are less frequent as I have less particulates in the oil. I have never had any gas treatment work as well as this one.

Awesome product

I like the product, but it was delivered damaged.  Not enough packing material in boxes to prevent damage.  Lost about 1 gallon total from the shipment

Marvel Oil fuel system lubricant bottle, centered front-facing view with 'Marvel Mystery Oil' label; used to lubricate fuel pumps, fuel injectors or carburetors and the top portion of cylinders and to reduce varnish and gum build-up in the fuel system; often used as a light lubricant for small metal parts during maintenance.
