Marvel Mystery Oil Original Oil Enhancer & Fuel Treatment is a legendary, multi-purpose additive designed to improve engine performance and longevity by cleaning and lubricating internal components. You will find that this unique petroleum-based formula effectively dissolves harmful sludge, gum, and varnish deposits that can lead to valve sticking and reduced fuel economy. This product feels incredibly versatile because it can be added directly to your engine oil to prevent breakdown under extreme temperatures or mixed with gasoline and diesel fuels to lubricate upper cylinders and fuel injectors. Because it has been a trusted staple in garages for over 100 years, this 32 oz bottle is a reliable solution for maintaining everything from classic cars and modern daily drivers to marine engines and agricultural equipment.

To get the best results for fuel system cleaning, you should add 4 ounces of Marvel Mystery Oil for every 10 gallons of gasoline or diesel at every fill-up. When using it as an oil treatment, you should replace 20 percent of your total oil capacity with this additive (for example, use 1 quart of Marvel for every 4 quarts of motor oil) during your regular oil change. You will notice the product has a distinct minty scent and a signature red color, which makes it easy to see the level in your fuel or oil system. It is a good practice to use this treatment consistently in older vehicles to help keep the internal seals pliable and the upper cylinder walls properly lubricated, especially if the vehicle sits for long periods.
