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.

Helps maintain cleanliness and smooth operation.

Provides lubrication for valve stems and upper cylinders.

Improves engine performance and gas mileage in aged cars.

This is such a wonderful product for an engine. My dad told me when he had several trucks at his business that he got one serviced and the mechanic told him the trucks engine was the most lubricated and well maintained he'd ever seen. Since then I give my car 3 “gulps” every other fill up.

Great for lubricating parts

[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.

This solution works well with the sticky gasoline gage reader in the tank for your dash readout operation. Otherwise, it will cost you an arm and leg to repair the unit inside the gas tank of it's NON-Reading on your gage panel. Just add what the bottle says to get the results.

Gas Gage Works Again

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

Been using marvel mystery oil since I was teenager . Imo it's best addictive  on market to protect your engine … cylinder heads …. Lubricant… oil and gas addictive .  I only use it with my gas … it improves performance and gas mileage and extends life of your engine . After you try bottle you will be hooked !! A product that improves performance… gas mileage and protects your engine !!!

My engines just keep running. I have used this for more than four decades I think. The last two cars I bought new and kept for over 17 years each, one I'm still driving. It is still running perfectly with no problems whatsoever with the engine (or anything else really). Can I tell you this is the reason - NO. Do I think it has helped - YES. I just had the recommended measure to my fuel tank with each fill up.

it just seems to work. the engines keep running.

THIS is the absolute best Gas %26 OR Oil additive you can buy for your engine's long life. THIS particular deal with Wal-Mart was a STEAL !! Come get IT !!

Marvel Mystery Oil because ITS THAT GOOD !!

This is the best stuff on the market the best product for the money I will continue to use it. My father used it, and I've seen it as a child and I will continue to pass it down to my children to use this product.

Great product I use it with every oil change and put a little in the gas tank
Great product I use it with every oil change and put a little in the gas tank

I use this in the race motors after the race. It keeps the cylinders well lubed and fights off the affects of the methanol.  
I also use it in the fuel lines as well as the fuel pump.

I have a 2012 FORD E-350 Super Duty Econoline. I added 4 ounces per 10 gallons of gasoline. I didn't add it to my oil when I changed it, but my vehicle no longer starts. It says this product DISSOLVES OIL AND HAS NO REAL BENEFIT FOR MY ENGINE THEREFORE DAMAGING IT! My engine was good before the use of this oil. I recommend just changing your oil or getting a mechanic to look at it before using this snake oil.

Doesn't work DO NOT BUY!!
